Achieving an emission pathway that would be compatible with limiting the global temperature increase to 1.5 °C compared with pre-industrial levels would require unprecedented changes in the economy and energy use and supply. This paper describes how such a transition may impact the dynamics of sectoral emissions. We compare contrasted global scenarios in terms of the date of emission peaks, energy efficiency, availability of low-carbon energy technologies, and fossil fuels, using the global integrated assessment model IMACLIM-R. The results suggest that it is impossible to delay the peak of global emissions until 2030 while remaining on a path compatible with the 1.5 °C objective. We show that stringent policies in energy-demand sectors—industry and transportation especially—are needed in the short run to trigger an immediate peak of global emissions and increase the probability to meet the 1.5 °C objective. Such sector-specific policies would contribute to lowering energy demand and would reduce the level of the carbon price required to reach the same temperature objective. Bringing forward the peak of global emissions does not lead to a homothetic adjustment of all sectoral emission pathways: an early peak of global emissions implies the fast decarbonization of the electricity sector and early emission reductions in energy-demand sectors—mainly industry and transportation.

Note that the residential sector refers to private housing only and is separate from the service (or composite) sector. We left the service sector out of the analysis as it represents less than 5% of total emissions in 2015 and as the representation of this sector is less detailed than other sectors in IMACLIM-R.
For a detailed description of the IMACLIM-R model, see: http://themasites.pbl.nl/models/advance/index.php/Model_Documentation_-_IMACLIM
See Bibas et al. (2015) for a thorough description of the representation of technical change in IMACLIM-R.
Non-CO2 GHG gases and emissions from land-use change are not modeled explicitly in this version of the model.
Note that global emissions are imposed over that period but not the sectoral shares of those emissions.
One family corresponds to one global emission constraint with a peak at year 2016, 2020, 2025, or 2030 and eight different combinations of technico-economic parameters.
Non-CO2 GHG gases and emissions from land-use change are not modeled explicitly in this version of the model. Cumulative CO2 emissions over 2010–2050 are compared with CO2 budgets from studies that account for the impact of non-CO2 gases on warming. Implicitly, this means that we are assuming non-CO2 gases emissions to be similar to the trends from those studies.
Threshold Exceedance Budget (TEB) and Threshold Avoidance Budget (TAB) are defined as follows: “TEB is the amount of cumulative carbon emissions at the time a specific temperature threshold is exceeded with a given probability in a particular multi-gas emission scenarios,” “TAB is the amount of cumulative carbon emissions over a given time period of a multi-gas emission scenario that limits global-mean temperature increase to below a specific threshold with a given probability” (definition from Rogelj et al. (2016), which detail the different types of carbon budget concepts used and their implications). TEB is expected to be higher than TAB.
Note that the results show direct emissions for the transportation and residential sector (i.e., excluding for instance the emissions associated with the production of electricity used for transportation). We account for both direct and indirect emissions in the industry sector.

Conflict of interest
The authors declare that they have no conflict of interest
• It may be impossible to delay the peak of global emissions until 2030 while remaining on a pathway compatible with a 1.5 °C world, whatever the policies in place to lower energy demand across sectors.
• Stringent policies in energy-demand sectors—industry and transportation especially—are needed in the short run to trigger an immediate peak of global emissions and increase the probability to meet the 1.5 °C objective.
• Sector-specific policies reduce energy demand and reduce the level of the carbon price required to reach the same temperature objective by 25 to 50% in 2030.
• Bringing forward the peak of global emissions does not lead to a homothetic adjustment of all sectoral emission pathways.
• An early peak of global emissions implies the fast decarbonization of the electricity sector and early emission reductions in energy-demand sectors—mainly industry and transportation.
This section provides a description of the parameters used for each scenario. Note that this description is very similar in its formulation to Guivarch et al. (2015).
In each sector, the region with the lowest-energy intensity is defined as the leader and its energy efficiency is triggered by energy prices. After a delay, other regions catch up with the leader region. We build two hypotheses (see Table 3) using the following parameters: maximum annual improvement in the leader’s energy efficiency, other regions’ speed of convergence (% of the initial gap after 50 years), and asymptotic level of catch up (% of the leader’s energy efficiency).
Development style of developing countries
This set describes either a mimetic development pattern for developing countries, which aim at adopting western lifestyles or a less carbon-intensive development pattern. We take into account infrastructure policies and the agents’ preferences for automobile transport and spacious individual dwelling (see Table 4).
Fossil fuel resources
The scenario alternatives on fossil fuel resources focus on the availability and prices of gas, coal, and coal to liquids.
In the model, global gas production capacities match demand growth until ultimately recoverable resources enter a depletion process. Variations in gas prices are indexed on variations of oil prices via an indexation coefficient (0.68, see Eq. 1) calibrated on the World Energy Model (IEA 2007). When oil prices increase by 1%, gas prices increase by 0.68%. Two alternative assumptions are used in this price indexation. Under the assumption of “relatively abundant and cheap” fossil fuel resources, this indexation disappears when oil prices reach US$80/barrel: beyond this threshold, fluctuations in gas prices only depend on production costs and possibly on the depletion effect. When depletion is reached, the price increases. Under the assumption of “relatively scarce and expensive” fossil fuel resources, gas prices remain indexed on oil prices regardless of fluctuations, but an additional price increase occurs when gas production enters its depletion phase. The price of gas in each region at year t is:
where pgas(t0) is the gas price in this region at year t0. As long as gas depletion has not started, τgas(t) in each region is:
where wpoil(t) is the world oil price at year t; wpoil(t0) is the world oil price at year t0. If depletion has started in this region, τgas(t) increases 5% each year, regardless of oil prices.
The oil market is modeled according to the following principles: (i) the OPEC can influence world oil prices before they approach a depletion constraint; (ii) oil supply cannot fully adapt to demand due to the geological nature of world oil reserves, i.e., the amount of economically exploitable reserves and technical constraints leading to inertias in the deployment of production capacities; and (iii) oil demand depends on agents’ decisions and on incentives aimed at increasing the production of alternatives to oil. The oil price reflects tensions between supply and demand:
Regional prices pk,oil are obtained by adding average regional production costs and a margin that includes both Ricardian and scarcity rents. In Eq. (3), ICj,oil,k is the intermediate consumption of goods from sector j to produce a unit of oil and pICj,oil,k is the intermediate consumption price for sector j for oil in region k. Qoil,k is the quantity of oil produced in region k. Ωoil,k is an increasing function of the utilization rate of production capacities Capoil,k in region k. loil,k is the quantity of labor per unit of oil produced in region k, taxoil,k,w is the labor tax rate in the oil sector in region . πk,oil is the markup rate in the oil sector in region k. The swing producer anticipates the level of capacities to reach a predefined target on the basis of projections of total oil demand and production in other regions.
Coal is treated in a different way than oil and gas in the model because coal resources are plentiful, which prevents coal production from entering a depletion process before the end of the twenty-first century. We describe the price formation on the world coal market in a reduced functional form linking variations in price to variations in production. This choice allows us to capture the cyclic behavior of this commodity market. Coal prices then depend on current production through an elasticity coefficient ηcoal: tight coal markets exhibit a high value of ηcoal (i.e., the price of coal increases if coal production increases). We make two assumptions for ηcoal. Under the assumption of “relatively abundant and cheap” resources, the sensitivity of an increase in coal price to an increase in coal production is quite low, so that the increase in coal production can be absorbed without price fluctuations (ηcoal = 1.3). Conversely, the increase in coal prices is very sensitive to any increase in coal production under the assumption of “relatively scarce and expensive” resources (ηcoal = 3).
Technologies penetrate markets according to their profitability but are constrained by a maximum market share which follows an S-shaped curve (Grübler et al. 1999). We consider two alternatives for each group of technologies. The high availability assumption corresponds to a higher maximum market share and faster diffusion than under the low availability assumption. The model also represents endogenous learning for some new technologies: the cost of the technology decreases with the cumulative investment in that technology. This mechanism is governed by a learning rate, and two alternative values are considered for this learning rate.
Low-carbon power generation technologies
The technologies considered are nuclear power and renewables. In the low availability assumption, it is assumed that the new generation of nuclear power plants is not available at all. The parameters are described in Table 6.
