emissions standards
Vehicle exhaust rules
Emissions standards are legal limits on pollutants released into the environment, typically from vehicles, factories, or power plants.
Governments set emissions standards to regulate carbon dioxide, nitrogen oxides, particulate matter, and other harmful substances: The new emissions standards require automakers to reduce tailpipe pollution by 40 percent.
Standards may specify maximum concentrations, total quantities, or required control technologies.
