摘要：Computable general equilibrium (CGE) models are regularly used for assessing the
impacts of environmental policies on the economy. This article applies this
methodology for global climate policy using the world GEM-E3 CGE model. An
emissions reduction scenario meeting the EU 2 degrees target is designed with
specific climate policy instruments, mainly relying on emissions trading. The
marginal cost is estimated at 40 US$/tCO2-eq in 2020 and around double that
figure for the year 2030. The GDP of the world economy would fall in annual
terms by 0.11% in 2020 and 0.17% in 2030, compared to the baseline scenario. The
world welfare would be annually reduced by 0.1% and 0.15% by 2020 and 2030,
respectively.
