Title : The economics of greenhouse gas mitigation: Insights from illustrative global abatement scenarios modelling

Authors : Andrew Gurney, Helal Ahammad, Melanie Ford

Abstract : In this paper the Global Trade and Environment Model (GTEM) and MAGICC are used to simulate a number of global emission mitigation scenarios devised by the EMF 22 Transition Scenarios group in which radiative forcing goals and the architecture of developing economies' participation in hypothetical mitigation actions are varied. This paper presents a reference case of the world economy to 2100 and analyses some key regional and global results for the various global mitigation scenarios, including emission prices, emission levels, primary energy consumption and economic growth.Modelling results suggest that a transition to a low-carbon world would require a significant decarbonisation of electricity generation without necessarily cutting the electricity output in the long run. With the uptake of hybrids and non-fossil-fuel technologies, the transport sector could make an important contribution to global abatement of greenhouse gases. Furthermore, with substantial international mitigation efforts and uptake of low- and/or zero-emission technologies, the achievement of 3.7 W/m2 and 4.5 W/m2 radiative forcing targets by the end of the century could occur at emission prices of up to $550/t CO2-e. However, achieving the 2.6 W/m2 (overshoot) radiative forcing target would require considerably higher emission prices and an immediate global mitigation action.
