Abstract

This paper provides an overview of the Global Trade Analysis Project (GTAP) Data Base, version 12 (hereafter referred to as GTAP 12). This latest version distinguishes 145 countries and 18 aggregate regions for 7 reference years (2004, 2007, 2011, 2014, 2017, 2019, and 2023) and details the annual value of economic flows, within and between economies, across 65 goods and services sectors at pre- and post-tax valuation. Central to this database are the bilateral trade and international transportation margin flows that link all countries/ regions in the world. GTAP 12 also marks the first instance in which the land use and land cover (LULC) data, classified into 18 agro ecological zones (AEZs), are incorporated into the standard database construction process, thereby resulting in consistent land information across all GTAP databases. This, along with the greenhouse gas emissions satellite data, will greatly facilitate the use of the GTAP framework in economy-wide studies of trade and environmental issues at the global and regional levels.
