MTA New York City Transit Bus Fleet Emissions, 1995 to 2006
NRDC kicked off a 'Dump Dirty Diesels' campaign in 1995 that led to New York City Transit's adoption in 2000 of its Clean-Fuel Bus Program. In 2006, NRDC hired Michael J. Bradley & Associates to study the reductions in emissions from NYC Transit buses since the start of that campaign. The study concluded that NYC Transit reduced particulate matter emissions from its buses by 97 percent and smog-forming nitrogen oxides emissions by 58 percent since 1995. The NYC Transit program is now being replicated by other transit fleets around the U.S. and the world.
