The Model for Global Responses to Anthropogenic Changes in the Environment (GRACE) was developed for economic analysis of climate change issues including mitigation, impacts, and adaptation. Since 2005, GRACE has been updated in line with the latest Global Trade Analysis Project (GTAP) database. So far, Norway has not been a specific region in GRACE. To include Norway in a new version of GRACE, we need a GTAP database that ensures consistency with the official national accounting data of Norway. This study describes how we adjust the GTAP v. 10 data to achieve this consistency. For this purpose, we apply the official input-output (IO) table of Norway for the year 2014 and the annually updated Table 11123 of the National accounts to adjust macroeconomic data of the original GTAP database for components of GDP like production, income, and expenditure. The balance between supply and demand of products is finally taken care of by introducing an additional parameter in the adjusted GTAP data as “changes in inventory” for all regions. The official energy accounts and CO2 emissions data of Norway are used to replace the corresponding data of Norway in the GTAP database.
