After the ICC Office of the Prosecutor’s 2016 Policy Paper on Case Selection and Prioritisation: Towards an International Crime of Ecocide?

The 2016 Office of the Prosecutor of the International Criminal Court (ICC) policy paper on case selection and prioritization is a significant development in that it highlights the possible role of the ICC in prosecuting environmental damage, illegal natural resource exploitation and land grabbing. For obvious reasons, however, the ICC Office of the Prosecutor policy paper could not expand the court’s current jurisdiction over ecocide which is dependent on a formal amendment to the ICC Statute and the policy paper is only an internal policy document. But more fundamentally it has been predicted that the 2016 ICC Office of the Prosecutor may signify the revitalization of the debate on how an international crime of ecocide could be conceptualised under international law and ultimately whether the ICC should have a broader jurisdiction over ecocide. This article aims to critically evaluate how a crime of ecocide could be conceptualised under international law, as well as to assess the limitations of conceptualising ecocide based on the narrow definition of the existing crimes under the ICC Statute. Moreover, this article aims to critically evaluate developments in past three and half years following the adoption 2016 OTP Policy Paper, and notes that the practice of the OTP in dealing with recent national communications and the ICC case law itself to date have not signified a considerable shift in interpreting the law in cases involving environmental damage, illegal natural resources exploitation and land grabbing. Therefore, they have done little so far to clarify the scope of the court’s existing jurisdiction over ‘‘ecocide’’.


I INTRODUCTION
On 15 September 2016 the Office of the Prosecutor (OTP) of the International Criminal Court (ICC) issued a policy paper on case selection and prioritization, which highlights a possible role of the ICC in prosecuting environmental damage, illegal natural resource exploitation and land grabbing committed in context of the existing crimes under the Rome Statute. 1 This is not the first initiative to galvanize the debate over the creation of a crime of ecocide in international law. In 2010, Polly Higgins, a leading advocate for the recognition of an international crime of ecocide, proposed that the UN Law Commission defined ecocide as the ''extensive damage to, of or loss of ecosystem(s) of a given territory, whether by human agency or by other causes, to such an extent that peaceful enjoyment by the inhabitants of that territory has been or will be severely diminished.'' 2 A more concrete step towards the establishment of a crime of ''ecocide'' (although limited to the European context) happened following a European Citizens'' Initiative which was launched in June 2012 aimed at achieving a joint EU position on the crime ecocide with the view of ''end[ing] ecocide in Europe'' and for adoption of a ''draft ecocide Directive.'' 3 Yet since the initiative failed to reach one million signatures in at least seven Member States required to instigate the Commission to adopt a legislative proposal, 4 the initiative was withdrawn in January 2013. 5 The Citizen's initiative was debated subsequently by the European Parliament's Environmental, Legal, Agricultural and Fisheries Committee in February 2015, but this has not led to concrete steps towards adoption of a ''draft Ecocide 1  Directive'' 6 given that the European Commission holds the exclusive power of legislative initiative and the limited role of the European Parliament to instigate the Commission to start legislative action. Despite the challenges faced by those initiatives, they provide evidence of an increased interest from citizens, politicians and the ICC itself -as evidenced by the 2016 OTP policy paper -in redefining the limits of the court's jurisdiction which could ultimately lead to the creation of an international crime of ecocide. 7 The four crimes that currently fall under the jurisdiction of the ICC are genocide, crimes against humanity, war crimes and the crime of aggression. 8 Thus at present the scope for the prosecution of environmental crime before the International Criminal Court (ICC) is very limited, given that the Rome Statute (1998) 9 primarily only recognises the court's jurisdiction for certain instances of environmental damage in the context of an armed conflict falling under the definition of war crimes, such as the oil spill caused by the Iraqi forces in the Persian Gulf during the Gulf War in 1991. 10 Ultimately it will be for future ICC review conferences to decide whether ecocide (or other international and transnational crimes, such as terrorism and drug trafficking) should be included in the ICC Statute. 11 Although the 2016 ICC OTP policy paper on case selection and prioritization is a significant development in that it highlights the crimes committed ''by means of, or that result in: the destruction of the environment, the illegal exploitation of natural resources or the illegal dispossession of land.'' 19 As will be further discussed below, the Global Diligence LLP Communication brought on behalf of the victims (''Filing Victims'') against Cambodia, although at the time of writing not having triggered preliminary examinations by the OTP, is largely regarded to have inspired the adoption of the 2016 OTC Policy Paper. The 2016 OTP has been welcomed by some commentators who noted that although not binding, the Policy Paper's focus on environmental harm as relevant to the OTP's decision to prosecute has improved the possibility of entrenching a ''green'' approach to interpreting the ICC Statute. 20 Moreover, the OTP's Policy Paper has been praised because of its potential to enhance the ICC's ability to deliver justice to victims of environmental harm and to produce incidental benefits in terms of environmental protection and which could also be used as tool to combat climate change. 21 This article aims to critically evaluate how a crime of ecocide could be conceptualised under international law and in particular to assess the limitations of conceptualizing the crime of ecocide based on the narrow definition of the existing crimes under the ICC Statute, as envisaged in the OTC's 2016 policy paper. Further, this article will evaluate the OTP practice and ICC jurisprudence in the three and half years since the adoption 2016 OTP Policy Paper in order to assess whether they have marked a considerable shift from their previous positions in handling cases involving environmental damage, illegal natural resources exploitation and land grabbing.
The second section of this paper begins with a discussion of how a crime of ecocide could be conceptualised under international law, taking account of historical developments including the existing international initiatives such as those proposed or adopted by the International Law Commission, the ICC and other international institutions, as well as the legal nature (international or transna-tional) and legal elements of an eventual crime of ecocide under the ICC Statute. This is followed by the third section which scrutinizes the impact of the ICC OTP 2016 policy paper on prosecutorial discretion and highlights the limitations in relying on the ICC's existing jurisdiction for the prosecution of ecocide. Section 4 presents the concluding remarks.

II CONCEPTUALISING A CRIME OF ''ECOCIDE'' UNDER INTERNATIONAL LAW
This section discusses how a crime of ecocide could be conceptualized under international law. It starts by looking into the historical developments aimed at creating an international crime of ecocide and whether ecocide could be regarded as an international or transnational crime. Finally, this section analyses the legal elements of an international crime of ecocide (in particular the mens rea and the actus reus elements) and ends with a discussion of whether certain human rights violations may fulfill the required elements of a crime of ecocide.

The Origins and Historical Developments Towards the Establishment of an International Crime of Ecocide
The origins of the term ''ecocide'' can be found in reactions to the use of the ''Agent Orange'' in the Vietnam war. 22 Arthur Galston, following the 1970 conference on ''War Crimes and the American conscience'', condemned Operation Ranch Hand and asked the international community, through the United Nations, to condemn and punish ecocide. 23  Any Hostile Uses of Environmental Modification (ENMOD) 24 , a global ''ecocide'' convention with a broader scope beyond armed conflicts was never formally adopted. It should be noted that EN-MOD itself is only of indirect relevance to international criminal law as it does not impose individual criminal responsibility for breaches of its provisions. Indeed, ENMOD is primarily useful as an interpretive aid for other provisions and principles under the ICC Statute that do entail individual criminal responsibility. 25 The first initiative by the International Law Commission calling for the criminalisation of offences against the environment was the Draft Code of Crimes Against the Peace and Security of Mankind (1954), adopted in second reading in 1996. 26 The original draft code recognised ''widespread environmental damage'' as a ''crime against the peace and security of mankind'' which could be defined as a war crime. 27 Significantly, the draft code envisaged penal protection under article 26 against ''wilful and severe damage to the environment.'' 28 It thus identified widespread environmental damage as a crime against the peace and security of mankind as a prerequisite for establishment of an international crime. It should be noted that in contrast to Article 22 (on ''war crimes'') of the same draft code, article 26 was not limited to the context of an armed conflict. 29 However, during the second reading of the draft code the special rapporteur recommended significant changes to Article 22, and the deletion of Article 26. 30  support in government comments on the draft adopted on first reading, and Article 26 faced strong opposition from member governments who have expressed doubt over whether environmental issues can affect the peace and security of humankind. 31 So the final version of the Draft Code adopted in 1996 has a limited scope to the criminalization of environmental offences in that it only applies to war crimes. The position of some national governments that have led to the deletion of Article 26 of the draft code is at odds with the expanding interpretation of ''peace and security of mankind'' given by the UN Security Council, 32 and with the development of the notion of ecological security. 33 international crime.'' 36 The seriousness of environmental offences is a crucial element in the ILC original definition of international crimes involving environmental damage. Indeed, according to Article 19 (3) (d) of the Draft Articles ''a serious breach of an international obligation of essential importance for the safeguarding and preservation of the human environment'' could constitute an international crime, such as ''massive pollution of the atmosphere and the high seas.'' 37 Hence according to the original ILC Draft Articles an international crime could include the serious breach by a State of an obligation essential for the protection of fundamental world interests. This would include peace and security of mankind, human rights, and safeguarding and preservation of the human environment. 38 The Articles on State Responsibility finally adopted in November 2001 by the ILC in its fifty-third session omit the reference to international crimes as triggering the criminal responsibility of States for environmental offences. 39  The ICRC Customary International Humanitarian Law Study also addresses the principles of customary international law that impose prohibitions on damaging the environment. Rule 43 clarifies that the international humanitarian law principles of distinction, military necessity, and proportionality apply to attacks against the natural environment resulting from military operations. 55 Moreover, the destruction of the environment during hostilities in the absence of any military objective is criminal, just as the destruction of civilian objects is criminal. 56 Yet even though serious environmental damage often accompanies armed conflicts and there is a well-established international legal framework governing environmental damage in armed conflicts, so far there have been very few prosecutions for environmental damage since the Second World War. 57 The discrepancy between the seriousness and scale of damage to the environment in armed conflicts and the absence of individual accountability is of considerable concern. 58 Indeed, despite the serious environmental damage that are inflicted in the course of armed conflicts, it is disappointing that Article 35 (3) of Additional Protocol I has not been the subject of prosecutions in international tribunals. 59 2.2 The ''Inter-'' and ''Trans-'' Nationality of Ecocide Another obstacle to the conceptualisation of ''ecocide'' is the extent to which it should reflect the distinction between ''crimes under international law'' and ''transnational crimes.'' Indeed, a doctrinal distinction is made between ''supranational crimes'' (or ''transnational crimes'' such as transnational environmental crimes), and ''crimes under international law'' which are those international crimes subject to the jurisdiction of an international criminal court or 54  tribunal. 60 Although those crimes which have an impact on one or more States (including transboundary environmental crimes) could be broadly considered international crimes, arguably environmental crimes cannot be defined as international crimes in the strict sense as understood under international criminal law which currently only recognises war crime, crimes against humanity, genocide, torture, crimes of aggression 61 (and according to some definitions, also international terrorism and maritime piracy), as international crimes. This allows one to distinguish crimes of cross-boundary effects, such as drug or human trafficking or illegal movement of hazardous waste, and other crimes which are susceptible to adjudication by an international criminal tribunal, such as the International Criminal Court, the International Criminal Tribunal for the Former Yugoslavia (ICTY), the International Criminal Tribunal for Rwanda (ICTR) or the Special Court for Sierra Leone. 62 According to Antonio Cassese and his co-authors, the existence of an international crime requires the following criteria to be met cumulatively: a) violation of international customary rules as well as treaty provisions; b) the rules are intended to protect values important to the whole international community and consequently bind all states and individuals; c) a universal interest in repressing those crimes; and d) if the perpetrator has acted in an official capacity (i.e. de jure or de facto state official), the state on whose behalf he has performed the prohibited act may be barred from claiming immunity to those state officials from civil or criminal jurisdiction of foreign states accruing under customary international law to state officials acting in the exercise of their functions. 63 It would not be particularly challenging for a definition of ecocide to fulfill the first three criteria. 64 Indeed, there is an increasing recognition that some serious types of transnational environmental offences impact on the peace and security of mankind and violate ''customary rules'' and ''uni-  63 Ibid, at 20. 64 Ibid.
versal values.'' Significantly, the UN Security Council recognized in 2007 that climate change poses a threat to peace and security of mankind. 65 This view was shared by the Extinction Rebellion protest group who have advocated recently for the ICC to play a role in prosecuting climate change-related damage. 66 Moreover, the Security Council has recognised that attacks on the environment have consequences in terms of international peace and security. 67 And according to Natalie Klein, illegal, unregulated and unreported (IUU) fishing is not only an environmental concern, and should be regarded as a maritime security concern of coastal states. 68 On the other hand, the fourth criterion concerning the immunity of state officials is of limited applicability to the rules of international criminal law in the context of international crimes involving environmental damage, as government officials will only in limited circumstances be directly responsible for environmental damage (possibly, for example, in the context of environmental crimes committed by state-owned companies or when environmental licenses are fraudulently issued). 69 This of course does not mean that the ICC jurisdiction is limited to international crimes committed by state officials in a governmental capacity (although war crimes, genocide and crimes against humanity are often committed by states officials). 65 69 See also, Pereira, above note 38.
As argued by Robert Cryer et al, with exception of the crime of aggression, the status of the perpetrator is almost always irrelevant to define international criminal responsibility. 70 Yet ''international environmental crime'' broadly defined (or ''latu sensu'') may include illegal trade in wildlife; 71 illegal trade in ozonedepleting substances; 72 and dumping and illegal transport of various kinds of hazardous wastes, 73 since there are international conventions requiring signatory parties to introduce, among others, penal measures against violations of those agreements. It is thus possible to broadly define certain types of environmental damage as international environmental crimes 74 ''(whenever) there is movement of goods across boundaries (i.e. smuggling etc) or a transboundary impact to offences.'' 75 Those offences could be classified as ''supranational crimes'' or ''transnational crimes,'' to be distinguished from ''crimes under international law'' which are subject to the jurisdiction of an international criminal tribunal. 76 It should be noted that illegal logging is not covered by any international convention establishing punitive measures and could not be considered ''international environmental crimes'' even in this broader sense. As regards illegal fishing, although no binding international agreements require states to criminalise it, the FAO has implemented a number of initiatives in 70  order to eliminate illegal, unregulated and unreported (IUU) fishing, calling on states to adopt sanctions which are ''of sufficient severity.'' 77 One commentator argued that this high number of international treaties and other instruments providing for prohibitions and punishment for environmental damage support the case for creation of an international crime against the environment in times of peace. 78 Of course, it is not that only crimes classified as ''international'' may be the subject of an international tribunal -any conduct potentially might -this being more a policy question of which crimes the relevant body setting up a court or tribunal want to establish. 79 Similarly, Frederic Megret takes an expansive interpretation and argues that internationally mandated domestic criminal law under international agreements could legitimately be considered part of international criminal law and that there is no clear criterion to fundamentally distinguish them from the supranational criminal law that is deemed partly worthy of prosecution by international criminal tribunals. 80 He goes on to argue that crimes in the first category may one day move to the second, and crimes in the second are always partly reliant on the mechanisms of the first. Following this more expansive interpretation suggested by Megret, it is possible to regard some forms of transnational criminal activities -including illegal wildlife trade, transboundary illegal waste movements, and illegal fishing -as forming part of the body of international criminal law. This rationale adds support for the case for a broader crime of ecocide under international law which would have the potential to encompass a wide range of prohibited transnational criminal activities. 77 85 Moreover, as will be further discussed below, ''specific intent'' is required for the commission of some of the Rome Statute crimes such as genocide. 86 Based on the codification attempts of the ILC discussed above, a combination of existing human rights documents, emerging Conventions in draft form, and various sources of soft-law, some publicists have suggested that there is a strong case for the recognition of an international crime of ecocide in cases involving serious environ- 81 Ibid. mental damage. 87 It is argued that the sheer harm caused by ecocide justifies its application during peacetime activities that destroy or damage ecosystems in a massive scale. In this vein, they have built the case that these environmental crimes could rise to the status of jus cogens -that is, a peremptory norm -similar to the prohibition on slavery or the general prohibition on the use of force, making it unlawful for states to derogate from that norm in future agreements. 88 It is then argued that causing severe environmental harm could lead to the breach of an erga omnes duty of care arising from international environmental law and human rights obligations and so to the commission of an international delict. 89 This argument mirrors an earlier view by Theoron Meron that ''there is a clear trend toward the criminalisation of international law.'' 90 He further argues that this ''trend is supported by simultaneous expansion of jurisdiction to prosecute crimes arising from both international and non-international conflicts, in both international and domestic tribunals, which in turn has been spurred by recent developments in customary law.'' 91 Although this statement concerned international criminal law in general and was not specific to the environment, it provides an early endorsement -or at least a recognition -of a trend towards criminalization in international law and institutions which has been confirmed following the creation of international courts and tribunals and subsequent state practices and which could eventually be extended to protect a wider range of environmental values. Therefore it appears crucial that it if the ICC jurisdiction were to be extended to include ecocide, it would have to take into account the scale and severity of the impact on the environment, for example the number of victims or the degree of harm caused to the environment. In this vein, under the 2016 OTP Policy paper the gravity of the offence is a significant element driving the start of preliminary investigations which ultimately limits prosecutorial discretion. 92  is in line with the enforcement of criminal sanctions for environmental protection at the national level which is regarded in many legal systems as the ultimum remedium. 93 Yet depending on how it is framed, the emphasis on the seriousness of the offence could pose a significant limitation to the definition of ecocide. It could mean that perhaps only the most serious incidents of environmental damage, for example the state failure to prevent a nuclear accident, 94 significant oil spills 95 or a major industrial accident (such as Bhopal disaster in India), 96 for example, could be recognised as acts of ecocide. 97 The conceptualisation of an international crime of ecocide based on the seriousness and likelihood of harm would be consistent with existing International Law Commission's initiatives aimed at defining environmental crimes as crimes under international law. Regina Rauxloh -borrowing from the Additional Protocol I to the Geneva Conventions -argued that the crime of ecocide should prohibit acts ''which are intended, or may be expected, to cause widespread, long-term and severe damage to the natural environment.'' 98 Although this definition is helpful in linking a definition of ecocide to a specific threshold of environmental damage, it is questionable whether the particularly high standards established under Additional Protocol I to the Geneva Conventions (applicable to ''war crimes'') should be replicated to the context of ecocide committed in the peacetime context or in post-conflict scenarios. For example, because the most serious aspects of the damage caused by Saddam Hussein's lighting of the Kuwaiti oil wells lasted a shorter time than expected, some commentators considered this to fall short of the long-term requirement of Additional Protocol I. 99 But even though the threshold under Article 8(2)(b)(iv) is particularly high, 100 it should be noted that if the crime is not being charged under that provision -and if there is no other requirement -the general seriousness/gravity requirement under Article 17(1)(d) would apply, which has been interpreted as a relatively low threshold by the Court to date. 101 Still, the relevance of the scale and severity of the impact of the environmental harm was also implied when the International Law Commission made reference to ''massive pollution of the atmosphere or the high seas'' as possible international environmental crimes in the original version of the Draft Articles on State Responsibility. 102 This means that an eventual extension of the ICC jurisdiction should include most issues of global environmental concerns and large-scale harm such as the depletion of the ozone layer, global warming-related damage (for example, the environmental damage caused by sea level rises) and illegal acts leading to the exhaustion of natural resources or extinction of species. 103 It should be noted that the clause referring to the natural environment under Article 8 (2)(b)(iv) of the ICC Statute is inspired by articles 35 para. 3 and 55 Additional Protocol I. 104 Their threshold is higher than ENMOD, which provides for disjunctive criteria. 105 Moreover, the reach of Article 8 (2)(b)(iv) is limited, because the 99 101 See for example Al Werfalli case, Second Arrest Warrant (ICC-01/11-01/17-13), para. 30, in which the Court stated that: ''The Chamber recalls that in determining whether a case is of sufficient gravity to justify further action by the Court, within the meaning of article 17(1)(d) of the Statute, it must have regard to: (i) whether the case captures those persons who may bear the greatest responsibility for the alleged crimes committed; and (ii) the gravity of the crimes allegedly committed, which may be examined following both a quantitative and a qualitative approach. With regard to the second element, the Chamber notes that cases encompassing a limited number of casualties or even those dealing exclusively with the destruction of buildings dedicated to religion have been considered to be sufficiently grave to justify prosecution.'' 102  provision only applies to international armed conflict and some scholars find this limitation of Article 8 (2)(b)(iv) particularly troubling. 106 Similarly, Rules 43-45 of the ICRC's study on customary law restates the principle according to the which, prior to launching an attack, precautionary measures shall be taken. 107 However, like the provisions of Additional Protocol I, neither the ICC Statute nor its Elements specify the meaning of the words ''widespread, long-term and excessive''. 108 A helpful definition of this threshold is found in the UNEP study which suggested that the notions of ''widespread'' should be read as encompassing an area on the scale of several hundred square kilometers, ''long-term'' as a period of months or approximately a season, and ''serious'' as involving serious or significant disruption to human life, natural and economic resources and other sources. 109 In light of those considerations, my view is that a crime of ecocide under the ICC Stature should be linked to a threshold of environmental damage based on the scale and severity of harm, but it should not be restricted to ''widespread, long-term and severe damage to the natural environment'' as set out under Additional Protocol I of the Geneva Conventions or Article 8 (2)(b)(iv) of the ICC Statute. Other commentators have similarly proposed an international crime of ecocide that is linked to a threshold of serious environmental damage, but using a broader terminology than the Additional Protocol I. For example Poly Higgins envisioned a case in which the Court's jurisdiction is limited to conduct that amounts to ''extensive destruction, damage to or loss of ecosystem(s) of a given territory''. 110 Similarly, Mark Gray argued that, to be described legally as ecocide, ecological damage must be ''serious, and extensive or lasting'', and result in ''international consequences.'' 111 106  If the rationale for criminalisation at the international level based on the seriousness of the harm or threat of harm to the environment is correct, then some of the most serious incidents of environmental damage could amount to acts of ''ecocide'', as mentioned above, this could include the state failure to prevent a nuclear accident, significant oil spills or a major industrial accident (such as Bhopal disaster in India). This would be particularly the case if environmental damage were to leave an ecosystem beyond repair, for example if a single nuclear disaster had the potential to leave the earth or particular ecosystems unfit to sustain human or animal and plant life. Moreover, when indigenous peoples are subject to serious human rights violations, including dispossession and grabbing of their lands and natural resources and the causing of environmental damage in their lands, it is very likely that the high threshold for establishment of an international crime of ecocide (or ''ethnocide'') would be met. 112 Yet as will be discussed in section 2.4. below, not every human right violation constitute an international crime and so it is not necessarily the case that human rights abuses committed against indigenous peoples equate to international crimes. 113 However, in light of the growing number of international and regional human rights instruments protecting indigenous peoples'' rights, 114 crimes committed against indigenous peoples should be regarded as particularly serious -and they embody the ''enthropocentric'' element enabling the OTP to bring charges for the international crimes currently recognised in the ICC Statute, including crimes against humanity and genocide. 112 As regards decisions of the international and regional courts and tribunals addressing violations of indigenous peoples' human rights in the context of extractive industry projects, see for example Saramaka People v Suriname ''concern to the international community as a whole.'' 120 In particular, the factors that will guide the ICC prosecutor include the ''scale, nature, manner of commission, and impact of crimes.'' 121 The manner of commission of a crime is to be assessed inter alia (…) on whether it results in ''the destruction of the environment or protected objects.'' 122 Moreover, when assessing the impact of crime the ICC prosecutor will give particular consideration to prosecuting Rome Statute crimes committed by means of, or that result in, inter alia the destruction of the environment. Therefore, the assessment of gravity will most certainly limit the exercise of prosecutorial discretion by the ICC prosecutor and inform her to act guided by the substantive and procedural provisions under the Rome Statute. 123,124 This suggests that the ICC prosecutor's discretion is not absolute and is limited by the Rome Statute and the ICC Rules of Procedure and Evidence. Indeed, it is in the assessment of the gravity of the offence that the ICC Prosecutor's Policy Paper will prove to be particularly influential, given the emphasis that it places on crimes committed by means of, or resulting in, the ''destruction of the environment'' and leading to ''environmental damage inflicted on affected communities'' as particularly serious crimes. 125 Yet the identification of individual offenders would not always be straightforward. This is particularly so in the case of illegal economic activities causing serious pollution which come from many sources as the identification of individual offenders often proves to be difficult, if 120 ICC OTP Policy paper, above n. 1, para. 35. 121 ICC OTP paper, above n.1, paras 32 and 37. 122 ICC OTP paper, above n.1 para. 41. 123  not impossible. 126 In fact, the difficulties in identifying and assigning liability to specific individual offenders would be a particularly strong argument for a wider range of mechanisms establishing State responsibility for environmental damage in the civil sphere to complement the mechanisms under international criminal law for assigning individual criminal liability. 127

A Human Rights-Centred Crime of Ecocide?
When serious environmental damage, illegal natural resources exploitation and land grabbing amount to human rights violations, arguably the case for criminalisation at the international level becomes even more apparent and imperative. 128 The importance of environmental protection to international human rights is now recognised in international environmental and human rights conventions and decisions of international and national courts and tribunals. 129 It could be argued that since the ICC has jurisdiction over the most serious crimes of concern to the international community, when defining the limits of those crimes the ICC should also prosecute environmental offences amounting to human rights abuses. Yet it is often not clear the exact point at which environmental damage crosses the threshold of a human rights violation, 130 and it is certainly 126 Mclaughlin, above n. 45, at 397-398. There is also the option of being more strategic in litigation and bringing some key cases that will develop the case law and allow for gradual emergence of new standards and other cases under its shadow. See for example Al Mahdi or Werfalli cases before the ICC. 127 139 William Schabas has also observed the growing cross-fertilization between human rights and the international criminal justice system. 140 For example prosecutions for incitement to genocide and hate speech as a crime against humanity at the International Criminal Tribunal for Rwanda raised difficult issues concerning the scope of freedom of expression. In the Trial Chamber decision, there was much reliance upon the case law of the European Court of Human Rights, as the judges sought to justify a rather high level of intrusion in the freedom of the media. 141 In one example of serious human right violations involving environmental damage and illegal natural resources exploitation in a regional context, the Social and Economic Rights Action Center and the Center for Economic and Social Rights v Nigeria case before the African Commission on Human Rights 142 concerned the negative health and environmental impacts of oil exploration in Ogoniland due to the contamination of water on indigenous land with lead and mercury affecting community health, particularly that of the children. Nigeria was found to have violated several articles of the African Charter and the African Commission called on the government to ensure protection of the environment, health and livelihood of the Ogoni people. 143 Moreover, the Commission called for the compensation to victims of human rights violations -including relief and resettlement assistance to victims of government raids -and undertaking Comprehensive Clean-Up Of Lands And Rivers Damaged By Oil Operators. 144 It is submitted that it is fundamental that environmental protection and human rights protection continue to evolve in close connection which would further advance the case for creation of an international crime of ecocide. The cross-fertilisation between the two fields, as recognized by the decisions of international courts and tribunals discussed above, further supports the case for a human-rights centred crime of ecocide. However, this could simultaneously raise questions about what the added value of the ICC jurisdiction would be in this context, given that there are existing human rights courts, tribunals and treaty bodies which can enforce environmental norms amounting to human rights violations. Yet the jurisdiction of international and regional human rights courts and tribunals is often limited to a certain region or in scope -providing remedies against the State rather than establishing individual (criminal) responsibility -and they are not strictly concerned with realizing international criminal justice for serious environmental damage or illegal natural resources exploitation. 145 As was observed by Emmanuel Dexaux, there is a significant difference between a justice system affording civil redress for damage suffered by victims by holding states responsible in the manner of the European Court of Human Rights does; and a justice system based on criminal responsibility of the perpetrators of international crimes, with the victims having no other place in the proceedings than as witnesses. 146 Hence human rights courts and tribunals could not provide an effective replacement for the ICC jurisdiction as a forum for prosecutions against individual offenders for ecocide. 144  age. 151 It is in the context of war crimes that the ICC OTP 2016 policy paper is expected to be particularly influential in driving the court to adjudicate over crimes committed through environmental means and illegal resources exploitation. It is possible that the court will come to clarify not only the scope of the ''environmental'' war crime under Article 8 (2)(b)(iv), but also whether the illegal exploitation of natural resources in conflict situations (such as illegal logging or the destruction and trafficking of endangered species) could amount to ''pillage'' and therefore to a war crime under Article 8 (2) (b) (xvi). 152 The clarification by the court on this question would be particularly significant in light of a string of Security Council Resolutions recognizing the interconnections between the exploitation of natural resources and armed conflicts, including in the contexts of the conflicts in Sierra Leone and the Democratic Republic of Congo. 153 Yet one study suggested that, even in the limited context of war crimes, the current international rules on armed conflict may be ineffective in the context of environmental crime. 154 In any event, the impact of the ICC OTP 2016 policy paper is likely to be limited even in the context of war crimes as it is only ''an internal document of the Office and, as such, it does not give rise to legal rights.'' 155 In the more recent ICC Trial Chamber VI case Bosco Ntaganda was found guilty of 18 counts of war crimes and crimes against humanity committed in the Democratic Republic of Congo in 2002-2003. 156 In the proceedings it was alleged that the UPC (Union Patriotic Congolose) entered into agreements with private companies providing for exploitation of natural resources in the territory under its control, in exchange for 151  payment. 157 However, illegal exploitation of natural resources played a minor role in Bosco Ntaganda's conviction for crimes against humanity, and the charges for the war crime of pillage related to a number of appliances, but not natural resources, and those charges were dismissed by the court. In fact, Ntaganda was not charged with pillage of natural resources but the Trial Chamber does make positive findings that the UPC entered into agreements with private companies for the exploitation of natural resources. 158 Moreover, even though in the Bemba case the Trial Chamber III found the MLC soldiers committed the war crime of pillaging throughout the 2002-2003 CAR Operations and throughout the areas in which they were present, 159 the Appeals Chamber found errors in the judgment and reversed all charges against the defendant for war crimes and crimes against humanity. 160 And as with the Ntaganda case, Bemba was not charged for pillaging natural resources but for pillaging a number of goods and appliances such as household items (such as furniture), business supplies, tools, money, vehicles and/or livestock. 161 This has led Jeremie Gilbert to note that there is a lack of a developed jurisprudence examining the connections between international crimes and natural resources and currently no systematic jurisprudence regarding pillage of natural resources. 162 157 Ibid, para. 440. 158 See (ICC-01/04-02/06-2359), para 440.

During its control over Mongbwalu, the UPC/FPLC showed interest in the factory of the Kilo-Moto gold mining company and also showed its intention to raise funds in relation to the exploitation of the gold mines. 159  It should be noted though that International Law Commission since its sixty-fifth session in 2013 has decided to work on the topic of the ''protection of the environment in relation to armed conflicts'' and an outcome document endorsed by the UN General Assembly may come to clarify the circumstances in which illegal natural resources exploitation may amount to a war crime. 163 In her second report, the Special Rapporteur addressed certain questions related to the protection of the environment in non-international armed conflicts, with a focus on how the international rules and practices concerning natural resources may enhance the protection of the environment during and after such conflicts. 164 The second report also addressed certain questions related to the responsibility and liability of States and non-State actors and has proposed seven draft principles for the protection of the environment in armed conflicts. 165 Yet because Article 8 (2)(b)(iv) and Article 8 (2) (b) (xvi) only apply in cases where environmental damage occurs in the course of an international conflict, they effectively preclude cases where environmental damage occurs during peacetime or in the course of a noninternational conflict. 166 Those limitations restrict the punitive and deterrence impacts of of criminal liability and hence fail to provide the basis for a broader recognition of an international crime of ecocide.

Beyond War Crimes: The Basis for and Limits of the ICC Jurisdiction Over Crimes Against Humanity and Genocide
Beyond the context of war crimes, a less explored issue among scholars and policy makers is the scope for environmental damage, illegal natural resources exploitation and land grabbing to be prosecuted under the existing crimes listed in Article 5 of the Rome Statute if it they meet the typologies of the crimes of genocide and crimes against humanity. Indeed, in case there is no consensus among the parties to extend the ICC over ecocide, the only other possible avenues for prosecution of environmental damage before the ICC would be in the context of war crimes, genocide and crimes against humanity. 163 See further, Marie G. Jacobsson, above note 146. 164 Ibid, Para. 64. 165 See second report of the Special Rapporteur (A/CN.4/728): draft principle 6 bis (Corporate due diligence), draft principle 8 bis (Martens Clause), draft principle 13 bis (Environmental modification techniques), draft principle 13 ter (Pillage), draft principle 13 quater (Responsibility and liability), draft principle 13 quinquies (Corporate responsibility), and draft principle 14 bis (Human displacement). 166 See also, Mwanza, above note 20.
The challenges in classifying environmental crime as falling under the umbrella of one of the existing crimes covered by the ICC statute is evident in the case of crimes against humanity. 167 Like genocide, crimes against humanity do not need to occur in the context of an armed conflict. The Rome Statute defines crimes against humanity as acts committed as part of a ''widespread or systematic attack directed against any civilian population, with knowledge of the attack'' 168 and includes murder, extermination, ''or other inhumane acts of similar character intentionally causing great suffering or serious injury to body or to mental or physical health,'' 169 which could include for example water contamination caused to kill a civilian population. But to what extent could environmental damage amount to a crime against humanity under the Rome Statute? Firstly, as per Article 7 (1) (k) of the Rome Statute, the attack to the environment would need to endanger human health in order to be recognized as a crime against humanity, thus it would leave the environment as such without effective legal protection. Moreover, the Rome Statute requires that the attack must be ''widespread or systematic''. This certainly limits the scope of this provision as many instances of environmental damage would not meet this threshold. As regards the requirement that the act is directed at a civilian population, when the continuous and foreseeable result of the extraction produces severe environmental damage which kills local populations, a policy to continue such extraction becomes tantamount to an official policy to carry out attacks against a civilian population. 170 According to Article 7 (2) (a) of the Rome State, this act must be pursuant to ''a State or organizational policy'' to commit such attack. The policy does not need to emanate from the State -non-State actors or private individuals who exercise de facto power can constitute the entity behind an organizational policy. 171 167  the ICC Statute. 176 The Communication, which is widely regarded to have inspired the adoption of the 2016 OTP Policy Paper on case selection and prosecution, alleges that the land grabbings amounted to a ''deportation or forcible transfer of the population'' which is defined in the Rome Statute as the ''forced displacement of the persons concerned by expulsion or other coercive acts from the area that they are lawfully present, without grounds permitted under international law.'' 177 It should be noted that the problem of land disputes in Cambodia had been highlighted previously by the UN Special Rapporteur on Cambodia. 178 However, to date no preliminary examinations have been initiated by the ICC prosecutor and little information is available on the case in light of a request of the ICC that the Communication is dealt with privacy. If the facts described in the Global Diligence Communication are accurate, it appears likely that the forced evictions in Cambodia would meet the elements of the chapeau of Article 7 in particular the ''widespread or systematic attack'' and potentially also the requirement that the attack is ''directed against any civilian population, with knowledge of the attack.'' 179 However, since the Cambodian government's economic policy was driven by the interests of foreign investors, one commentator suggested that the forced evictions may not amount to a ''State or organizational policy'' as required under Article 7 (1) of the ICC Statute, 180 and this may help to explain the reluctance of the OTP to initiate preliminary examinations more than 5 years since the Communication was filed. Yet in this regard the Communication draws attention to the statement of the Extraordinary Chambers in the Court of Cambodia (ECCC) that ''[e]conomic policy is not one of the grounds recognised under international law that justifies forced transfer of a population'' 181 and it is not evidence from a reading of Article 7 (2) (d) that a state policy of forced evictions may be justifiable on economic grounds Despite the failure of those two communications to trigger the OTP to iniate preliminary examinations to date as was hoped following the publication of the 2016 OTP Policy Paper, it should be emphasized that the very existence of OTP Communications is difficult to monitor. As Fairlie highlighted, the practice of the Office has been ''to keep both the requests and subsequent analyses private''. 182 Therefore only Communications that the authors themselves have publicised are generally available to the public. 183 Even though the 2016 Policy Paper had the potential to encourage more non-governmental organizations to bring communications before the OTP for the conduct described in the paper, it is difficult to ascertain the success rate of existing Communications as they are only occasionally made available to the general public.
An even higher threshold would be required to link environmental damage with acts of genocide, in violation of the UN 1948 Genocide Convention 184 and Article 6 of the Rome Statute, thus potentially attracting the jurisdiction of the International Criminal Court. 185 The implications of this would be significant. This is so not only because the term ''ecocide'' was coined by analogy to the crime of ''genocide'', but also because the crime of genocide carries the highest degree of social and political disapproval among the existing international 181  crimes. 186 Yet there would be several legal challenges for environmental damage, illegal natural resource exploitation and land grabbing to be classed as genocide. One evidentiary burden would be to fulfill and prove certain elements of the crime of genocide which requires ''specific intent of exterminating one ethnic group.'' 187 In particular, even if acts such as ''killing members of the group'' (committed via an environmental medium) could in principle meet the actus reus element of the crime of genocide, it would still be challenging for the ICC prosecutor to establish that an environmental offence intended to ''destroy a group.'' Hence it has been suggested that defining international environmental crimes as crimes against humanity could prove more meaningful in that it covers many of the same acts that would normally fall under the rubric of genocide, but without the higher scienter element of demonstrating a ''specific intent to destroy one ethnic group.'' 188 Indeed, ''knowledge of the attack'' is the mens rea required for the establishment of the crime against humanity. This appears to encompass acts committed not only with intention but also with recklessness, which tends to be the case with a considerable number of environmental offences. Yet the ability of the OTP to prosecute crimes against humanity committed via reckless acts appear to be limited considering the history of negotiations of the Rome Statute. As noted by William Schabas, during the negotiations of the ICC Statute state parties saw little reason to define recklessness ''as it is not an element in the definition of any of the offences within the jurisdiction of the court.'' 189 In this regard, in the Ntganda Trial judgment the court stated that: ÔThe Chamber agrees with previous rulings that the phrase Ôwill occur in the ordinary course of events' as laid down in Article 30(2)(b) and (3) of the Statute which requires Ôvirtual certainty' 190 Accordingly, any lower threshold, such as dolus eventualis, recklessness and negligence, is insufficient to establish Ôintent' and Ôknowledge' in relation to a consequence under Article 30(2)(b). ' 191 Another significant limitation of classifying environmental offences as genocide (or crimes against humanity) is that these crimes require a specific result (e.g. ''killing members of the group''), but it would not allow the prosecution for conduct which is potentially harmful to the environment or human health. This is a significant limitation in particular in light of the central role played by the precautionary principle under international environmental law. 192 Still, there is one precedent in the ICC's own practice for this. In the context of the Al Bashir arrest warrant, the Pre-Trial Chamber found a nexus between the underlying environmental harm (water contamination) and the crime of genocide. 193 The Chamber noted that: Ôone of the reasonable conclusions that can be drawn is that the acts of contamination of water pumps and forcible transfer coupled by resettlement by member of other tribes, were committed in furtherance of the genocidal policy, and that the conditions of life inflicted on the Fur, Masalit and Zaghawa groups were calculated to bring about the physical destruction of a part of those ethnic groups. ' 194 In light of those considerations, the Chamber found that there were reasonable grounds to believe that the elements of the crime of genocide by deliberately inflicting on members of the target group conditions of life calculated to bring about the group's physical destruction, as provided for in article 6(c) of the ICC Statute, were fulfilled. 195

Evaluation of the Potential for OTP Prosecutions for Environmental Damage in the Context of the Existing International Crimes
It is clear from the above analysis that although it is possible in principle for individual criminal liability to be assigned for environmental damage under the existing crimes covered by the Rome Statute, the main limitation is that the prohibited acts of ''ecocide'' would amount to a serious crimes against persons, committed through environmental means. 196 Hence ecocide would be conceived primarily from an anthropocentric perspective. This helps to explain why, beyond the academic discourse, there has been little policy debate on enforcing environmental rights under the rubric of crimes against humanity or genocide. The above analysis suggests that it would be difficult for the ICC to bring effective prosecutions against international crimes involving environmental damage which fall under the umbrella of the existing crimes recognized under the ICC Statute beyond the limited context of war crimes. Moreover, it has been suggested that ''even if the International Criminal Court is inclined to pursue environmental damage from an internal armed conflict, the specific standards and norms are unclear, and the danger exists that a person might be charged for something he or she did not know was a crime.'' 197 It could be argued that this runs contrary to the principle of legality, which requires that international (criminal) norms are clearly defined. Thus the principle of legality is a barrier to the prosecution of international environmental crimes committed under the umbrella of the existing ICC Statute crimes, such as crimes against humanity or genocide. 195 Ibid, para. 39. 196  It is to be hoped that that the implementation of the 2016 OTP policy paper -and the eventual prosecution by the ICC of the limited range of environmental crimes currently falling under the Rome Statute -will bring some clarity to the scope of the court's existing jurisdiction in this area. Yet an eventual amendment to the ICC Statute establishing a specific ''crime against the environment'' (beyond the context of war crimes and other existing international crimes) 198 would make the principle of criminalisation clearer to the regulated community, increasing deterrence and therefore would be more consistent with the legality and fair labelling principles.

The Quest for Corporate Accountability for Ecocide
As was discussed above the ICC currently only has jurisdiction over international crimes committed by individuals, and not States. But another significant limitation of the ICC Statute is that it currently does not recognise the concept of criminal liability of corporations for international crimes. 199 Although there were proposals at the Rome Conference that led to the adoption of the ICC Statute to include a regime for criminal liability of legal entities, those proposals were rejected. 200 Indeed, direct corporate accountability would necessitate an amendment to art 25 of the ICC Statute, which gives the ICC authority only over human actors. 201 Hence one important limitation of the ICC jurisdiction is that it can exercise little scrutiny over the role of corporations in international crimes. 202 Yet one commentator suggested that while the 2016 OTP Policy Paper will not change the ICC's jurisdiction over corporate crimes, it may encourage the prosecution of business officials, which would be an important development from the perspective of business and human rights. 203 In this vein, corporate ''aiding and abetting'' could be part of a framework for holding corporate officers accountable for violations of international criminal law. 204 It is anticipated that the lack of jurisdiction over corporate crimes will represent a considerable barrier to the effective prosecution of ecocide by the ICC, which is of concern especially considering that corporations are responsible for the majority of environmental offences. Corporate responsibility for environmental damage and illegal natural resources exploitation is also endemic not only in the peacetime context but also in internal and international armed conflicts in resource-rich countries which have led to major human rights violations around the world. 205 Therefore, an extension of the ICC jurisdiction would have limited scope to the context of the operations of multinational corporations and other economic operators in the environmental and natural resources sectors, as they are often able to shield behind the corporate veil which represents a significant barrier to effective prosecutions. This is also complicated by the separation of legal personality be-tween parent companies and subsidiaries recognized in many legal systems which limit the effectiveness of civil remedies available to local communities and for remediation of the environment. This further illustrates the limitations of the current penalties and remedies predicated in the Rome Statute which often fail to reflect the remedies and penalties regarded to be effective for the enforcement of national environmental laws such as environmental remediation, as well as penalties more specific to corporate entities in particular license revocation and corporate probation orders. 206 This limitation in penalties and remedies is particularly striking given that unlike the other international criminal tribunals before it, corrective and reparative justice is one of the distinguishing characteristics of the ICC. 207 As was discussed above the International Law Commission since its sixty-fifth session in 2013 has been working on the topic of the ''protection of the environment in relation to armed conflicts'' and an outcome document endorsed by the UN General Assembly has attempted to clarify the circumstances in which corporations may be held liable for illegal natural resources exploitation and environmental damage. 208 Under the ''Draft principles on protection of the environment in relation to armed conflicts, adopted by the Commission on first reading,'' Principle 10 on ''Corporate Due Diligence'' states that States should take appropriate legislative and other measures ''aimed at ensuring that corporations and other business enterprises operating in or from their territories exercise due diligence with respect to the protection of the environment, including in relation to human health, when acting in an area of armed conflict or in a postarmed conflict situation.'' Moreover, the principle of corporate accountability is embedded in Principle 11 which directs States to ''take appropriate legislative and other measures aimed at ensuring that corporations and other business enterprises operating in or from their territories can be held liable for harm caused by them to the environment, including in relation to human health, in an area of armed conflict or in a post-armed conflict situation.'' 209 Even though there is considerable academic debate on whether criminal sanctions are effective or indeed necessary when applied to corporate entities, 210 it is submitted that the accountability of corporations should be recognized under the ICC Statute. In particular, powerful international non-state actors currently face limited risk of accountability under the national laws of some host states -and limited or no liability under international law -would have to act more diligently in the host countries where they operate. This is particularly the case of multinationals corporations, 211 but this should also apply to international financial institutions which fund projects that damage the environment. 212 . This view is echoed by Regina Rauxloh who argues that: ÔGiven the significant contribution of corporate actors to global environmental problems, the inclusion of legal persons within the gamut of international criminal liability would provide an avenue to end to the facto immunity which multinational corporations enjoy for the most serious environmental damage.' 213 Yet as not all legal systems recognise the criminal liability of corporations, it would be challenging for the ICC Statute to reconcile those disparate approaches concerning the assignment of criminal responsibility to corporate entities. 214

IV CONCLUDING REMARKS
Although the ICC OTP 2016 policy guidance on case selection and prioritisation is a positive development, it has so far not brought a major change to the status quo. Fundamentally, it does not change the current position that environmental crime may be regarded as serious crimes under national law but not under international law outside the limited existing ICC jurisdiction over environmental crime. Still, by emphasizing the seriousness of environmental damage, illegal natural resources exploitation and land grabbing in the context of the ICC's existing crimes, the ICC prosecutor's policy guidance could be regarded as an important step towards the establishment of a crime of ecocide under international law. But the first more immediate legal implications of the ICC OTP policy paper are that it may trigger the court to clarify not only the scope of the ''environmental'' war crime under Article 8 (2)(b)(iv), but also whether the illegal exploitation of natural resources in conflict situations could amount to ''pillage'' and therefore to a war crime under Article 8 (2) (b) (xvi). Yet it is less likely that those developments will lead the ICC in the near future to recognize that ecocide falls under the definition of genocide or crimes against humanity, as there are only a limited number of scenarios in which this would be possible given the high threshold required for establishing those offences.
But despite the excitement of some international environmental and criminal lawyers, academics and NGOs following the publication of the OTP policy paper, as of March 2020 (i.e. three and a half years since the publication of the 2016 OTP policy paper), no investigations or prosecutions have been initiated by the OTP for war crimes, crimes against humanity or genocide in which environmental damage, illegal natural resources exploitation or land grabbing were regarded to be aggravating circumstances in the case selection and investigation criterion. 215 It is also not encouraging that two recent Communications brought before the OTP have not led to preliminary examinations, that is the large scale governmental land grabbing in Cambodia and the ''Lago Agrio Victims'' victims for alleged crimes against humanity committed in Ecuador, even though it is difficult to ascertain the overall success rate of the Communications filed before 215 See ICC OTC Report on Preliminary Examinations Activities (2018), available at https://www.icc-cpi.int/itemsDocuments/181205-rep-otp-PE-ENG.pdf. See also, OTC Report on Preliminary Examination Activities 2019, 5 December 2019 https:// www.icccpi.int/itemsDocuments/191205-rep-otp-PE.pdf (accessed 30 March 2020) of the OTP as they commonly are not publicised. Moreover, the illegal exploitation of natural resources played a minor role in Bosco Ntaganda's conviction by the ICC in July 2019 for crimes against humanity, and the charges for the war crime of pillage related to enemy property but these did not involve illegal exploitation of natural resources, and in any event those charges were dismissed by the court. In addition, the mandate of the incumbent ICC prosecutor, Ms Fatou Bensouda, expires in early 2021 (i.e. 9 years since her appointment in December 2011), and it is not clear whether the new ICC prosecutor will pursue a similar policy guidance on case selection and prioritization.
It is to be hoped that if the ICC OTP eventually brings successful prosecutions concerning illegal natural resource exploitation, environmental damage and land grabbing in the circumstances envisaged in the OTP 2016 policy paper, then a particularly strong case could be made for the court to have a broader jurisdiction over ecocide in post-conflict and peacetime scenarios. With the recent unfortunate passing of a world leading advocate for the recognition of an international crime of ecocide, and with the recent rise of some populist and nationalist governments and political parties that have a low environmental protection record and little or no regard for environmental concerns, it is to be hoped that civil society and other stakeholders concerned will continue to get mobilized to call on law and policy makers to advance the case for creation of an international crime of ecocide. I have previously argued that although there are strong arguments for extending the ICC jurisdiction over ecocide, 216 the ICC jurisprudence and OTP practices needed further testing. 217 Although the 2016 OTC Policy Paper provided a promising basis for testing the court's jurisdiction, unfortunately so far it is difficult to make a strong case for extending the court's jurisdiction over ecocide on the basis of the prosecutorial and jurisprudential practices that have followed the publication of the 2016 OTC Policy Paper. 216 See in particular, Higgins, above note 2; and Mwanza, above note 20. 217 Pereira, R.
