Emissions of nitrogen oxides (NOx), sulfur dioxide (SO 2 ) and toxics like mercury add further to the health and environmental burden of fossil fuels. Particulate matter (PM2.5) is a particularly nasty pollutant, contributing to a range of cardiovascular and lung diseases and even causing death.

Older vehicles (pre-2004) make up 19% of the state’s passenger vehicles and only 12% of miles driven, yet they emit almost 3 times as much smog-forming, nitrogen-oxide pollution as all 2004 and later vehicles combined. These pollutants react in the atmosphere to form harmful particulate matter pollution known as PM 2.5.
