 Since 1990, exhaust emissions of **nitrogen oxides**, **NMVOC**,  and **carbon monoxide** have decreased sharply due to catalytic-converter use and engine improvements resulting from ongoing tightening of emissions laws and improved fuel quality.  Since 1990, exhaust emissions of **nitrogen oxides**, **NMVOC**,  and **carbon monoxide** have decreased sharply due to catalytic-converter use and engine improvements resulting from ongoing tightening of emissions laws and improved fuel quality.
