Comparing Madrid and Salvador GHG emission inventories: Implications for future researches

This paper compares the Greenhouse Gas (GHG) emission inventories of Madrid and Salvador and discusses some implications for future researches, focusing on city-level carbon accounting (CLCA) of emissions from urban supply chains (USC) and final consumers. To carry out this study, secondary data were collected from official documents of municipal governments of these two cities. According to the results, there are differences in stationary energy GHG emissions due to the big distinction concerning electricity emission factors used by each city. Air transportation GHG emissions are also very different. These two cities share some common figures regarding road transportation and per capita waste sector GHG emissions. In the conclusion section, we discuss opportunities for improvement of the cities’ GHG emission inventories as well as some implications for policy-making and future researches on carbon accounting, with focus on an integrated production-consumption system.
