Abstract
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.

Summary
Estimates show that the Greenhouse Gas (GHG) emissions caused by three European consumption areas (food, mobility and housing) showed no significant reductions between 2000 and 2007. Salvador is at an initial stage of the development of GHG emission inventories under the GPC framework This comparison between GHG emission inventories from two cities with different trajectories regarding their experiences in producing air pollutant emission inventories could provide useful contributions toscholars and practitioners improving the quality of CLCA methods. This comparison acts as an evaluation method for the GHG emission inventories of Salvador and Madrid. This paper contributes to put into discussion some challenges regarding the necessity of a future urban carbon accounting academic research agenda to switch the focus from current GHG inventories to an integrated production-consumption carbon accounting system
