The reductions in passenger vehicle emissions that have been achieved since the mid-twentieth century are a great environmental success story. Government regulation of tailpipe emissions and private investments in breakthrough technologies such as the three-way catalytic converter have reduced emissions of nitrogen oxides, carbon monoxide, and hydrocarbons by 75 to 90 percent at a relatively small cost to consumers. Since California first established emission standards for passenger vehicles in the 1960s, different regulatory approaches have been adopted by the United States, Japan, and Europe, and each has been emulated to some degree in other parts of the world. Significant work remains to replicate these successes throughout the rest of the global fleet.

The massive impact of passenger vehicles on climate also remains to be addressed. The transportation sector is responsible for about one-quarter of energy-related greenhouse gas emissions worldwide. Passenger vehicles account for just under half of this total, and will remain the predominant source of these emissions for the foreseeable future.

Euro VI for Brazil: A clear path for cleaner skies
In early February, CETESB announced new phases for Brazil’s vehicle emission standards for HDVs, LDVs, and motorcycles. This is an opportune moment, then, to highlight the significant benefits that will accrue to Brazil if the new standards for HDVs align as closely as possible with the European Union's Euro VI standard.
