Structural decomposition analysis of greenhouse gas emissions: Application to the Aquitaine region (In French)

In order to reach greenhouse gas (GHG) emissions reduction target becoming more and more restrictive, regions have to be invited to implement, in consultation with their nation, a climate plan, henceforth regionalized. The effectiveness of its implementation requires dynamic studies which necessitates a range of statistical data. However, most countries have a poor regional accounting. This is particularly the case for France. To enable us to regionalize the national climate plan, we applied for the Aquitaine region, situated in southwest of France, the structural decomposition analysis. The results from this analysis compared to data from the national statistical institute (INSEE) shows the interest of this analysis.\r\nThe interest of structural decomposition analysis is extended by the possibility to carry out, from the obtained results, two types of studies: the first one is retrospective and the other one is prospective. The retrospective study aims to quantify between 1999 and 2005 the evolution of greenhouse gas (GHG) emissions for 47 sectors and to select the main factors responsible of the evolution of these emissions for the Aquitaine region. Regarding the prospective analysis, a baseline scenario was constructed by using the Bootstrap method in order to estimate the impacts of the regional climate plan target on its GHG emissions for the year 2013.
