GTAP Research: Towards An Integrated Data Base for Assessing Greenhouse Gas Mitigation

Project Sponsor
The Methane and Sequestration Branch of the US Environmental Protection Agency (USEPA)

The main goal of the EPA sponsored GTAP project (hereafter, GTAP/EPA project) is to develop a land-use and greenhouse gases (GHGs) emissions Data Base for use in a computable general equilibrium (CGE) framework. This project runs from 2002 to 2005.

Growing research demands for integrated assessment of GHGs issues have motivated construction of a Data Base of land use and GHG emissions for use with CGE models. Many economic analyses of climate policies use CGE models of the global economy to trace GHGs emissions, to evaluate costs incurred, and to assess the spill-over effects of GHG policies via international trade and sectoral interaction. The GTAP Model is one of the leading CGE models of global dimension. With its Data Base covering inputs/outputs and bilateral trade of 57 commodities (and producing industries) of each 66 countries/regions, GTAP is able to capture broad sectoral interactions within domestic economy and international trade effects as well.

The Global Trade Analysis Project (GTAP) has filled an important need in the integrated assessment community by providing regular updates of a world-wide input-output and bilateral trade data sets with significant disaggregation of regions and sectors, plus energy volume data. This GTAP/EPA project aims to further extend the GTAP Data Base to fill the gap of links between land use changes and net GHGs emissions from agriculture and forestry. The extended GTAP Data Base will cover major GHGs from all sources, with a special focus on GHG emissions related to changes in land use and management practices in agriculture and forestry (e.g., deforestation and afforestation). The GTAP/EPA project will also identify a methodological approach to integrate GHGs emissions from agricultural and forestry activities into the standard GTAP Model. Cost features of alternative GHG abatement technologies are to be presented in the model.
