Uso de combustíveis e emiss?es de CO2 no Brasil: um modelo inter-regional de insumo-produto

摘要

This study quantifies CO2 emissions caused by consumption of natural gas, alcohol and petroleum derivatives for six Brazilian regions, and evaluates the impact of possible policies for emission control. The connection between the level of activity and CO2 emissions for each energy input is presented for the six regions considered, detailing the portion of the total emissions caused by final demand, inter-industry consumption and household consumption. The model was also used to make simulations in order to evaluate the economic effects of a hypothetical restriction on emissions and the effects that an emission tax would cause.
