Regionalising the Results of a National Structural Decomposition Analysis of Greenhouse Gas Emissions: An Application to Aquitaine Region

Tougher restrictions on greenhouse gas (GHG) emissions imposed by both national and international institutions are compelling regions to implement climate plans. However, the constraints of available statistics mean there is a shortage of regional-level information. We develop a method for regionalising the results of a national structural decomposition analysis for identifying the main factors contributing to the changing pattern of GHG emissions both at macro-economic level and at sectoral level. An illustration was carried out for the Aquitaine region. Results indicate that the method is relatively effective at least at the macroeconomic level given the statistical constraints.
