Equality, justice and feasibility: an ethical analysis of the WBGU’s budget approach

According to the Budget Approach proposed by the German Advisory Council on Global Change (WBGU), allocating CO2 emission rights to countries on an equal per-capita basis would provide an ethically justified response to global climate change. In this paper, we will highlight four normative issues which beset the WBGU’s Budget Approach: (1) the approach’s core principle of distributive justice, the principle of equality, and its associated policy of emissions egalitarianism are much more complex than it initially appears; (2) the “official” rationale for determining the size of the budget should be modified in order to avoid implausible normative assumptions about the imposition of permissible intergenerational risks; (3) the approach heavily relies on trade-offs between justice and feasibility which should be stated more explicitly; and (4) part of the approach’s ethical appeal depends on policy instruments which are “detachable” from the approach’s core principle of distributive justice.
