Produção, consumo e aquecimento global no Brasil : sob a ótica dos subsistemas

This paper analyzes the impact of consumption on the generation of greenhouse gases (GHG) in Brazil from 1995 to 2012 based on emission inventories and input-output matrices using the  methodology of the subsystems or vertically integrated sectors. The results show that the  "Agricultural and Livestock" sector and the subsectors "Agricultural and Livestock" and "Food  and Beverage" were responsible for most of the GHG generation in Brazil and that the "Energy" and "Transport" sectors/subsystems should be prioritized both by the point of view of  production as well as the point of view of consumption.The comparison between GHG generation by the sector and the corresponding subsystem provides a useful indication of what should be  the focus of public policy to reduce the generation of these gases: production (is the case of sector "No Metallic") or consumption (is the case of “Food and Beverage” subsystem). In addition, the matrix of composition of GHG emissions by sectors and subsystems allows to calculate the impacts of these policies.
