Air pollution concentrations have been rapidly increasing in the major urban areas of Brazil caused mainly by the increasing use of vehicles. Policies to control car emissions in Brazil have relied basically on mandatory emission standards and subsidies for specific cleaner technology resulting in substantial decrease of car emission rates. Nevertheless‚ taxes on car sales‚ differentiated by vehicles’ size and fuel‚ have also influenced car emission patterns. This paper analyses the compliance

explain some of the relationships between energy consumption and air pollution. Personally‚ when I first started thinking about the topic‚ I thought I already had the answers. The equation was pretty simple and did not take much thought: higher energy = higher air pollution. This thought was incorrect‚ as I quickly found out. The very first website looked at showed that over the last thirty years‚ energy consumption and air pollution do not always go hand in hand. However‚ in some places throughout
