Description of model

SGM is a computable general equilibrium model with emphasis on demographics, resources, agriculture, energy supply and transformation, energy intense industries, household consumption, and government expenditure. The model is used to project energy consumption and greenhouse gas emissions but its main relevance is its use in evaluating the economic impacts of climate change policies and the use of technologies for emissions mitigation.

Particular relevance

The SGM model is relevant in assessing the socio-economic impacts of  climate change mitigation policies, with a specific focus on resources, agriculture and energy-intensive industries.

Model applications

Analysis of climate policies under uncertainty with TIAM and the new climate module. The objective of this paper is to use TIAM to assess the feasibility, cost, and means of maintaining global temperature increase within the  2 ºC to 3ºC range (long term), under high economic and climate uncertainty

The Role of Nuclear Energy in Long-Term Climate Scenarios: An Analysis with the World-TIMES Model - Most of the emission scenarios of IPCC show an important role for nuclear energy to satisfy energy demand in the long term. The authors' objective is to analyze the role of nuclear energy in long-term climate scenarios using the World-TIMES bottom-up model. (
