The OECD ENV-Linkages General Equilibrium (GE) model is the successor to the OECD GREEN model for environmental studies, which was initially developed by the OECD Economics Department (Burniaux, et al. 1992) and is now hosted at the OECD Environment Directorate. GREEN was originally used for studying climate change mitigation policy and culminated in Burniaux (2000). It was developed into the Linkages model, and subsequently became the JOBS/Polestar modelling platform that was used to help underpin the OECD Environmental Outlook to 2020. A version of that model is also currently in use at the World Bank for research in global economic development issues. Previous work using the model includes development of a baseline to 2030 and a study of the consequence of structural change (including some environmental implications) associated with economic growth. Much of the applied work with the model is reported in various chapters of the OECD Environmental Outlook to 2030 (2008). Exploration of the model’s properties and some sensitivity analysis is reported in OECD (2006).
