California is the frontier for development of environmental regulations and innovative programs designed to reduce emissions from existing diesel-powered vehicles. Decades of effort to reduce diesel emissions enable the diesel industry and California to set the pace... and assure a strong future for diesel power in California.

Diesel engines drive most of the tractors that plow fields and move dirt, and have made a dramatic contribution to the increase in productivity that has exemplified California agriculture since World War II.
* Diesel fuels the trucks, trains and ships that move most of the freight carried in the state.
* Buses, which transport two-thirds of the state's transit passengers, are primarily diesel-powered.
* Most fire trucks and other heavy emergency vehicles also use diesel. Even the emergency standby generators that powered hospitals and other critical facilities during the 2000-2001 energy crisis are almost exclusively diesel.

What is clean diesel technology?

Clean diesel is an evolutionary systems-based process that combines advancement in diesel engines, cleaner burning diesel fuel and emissions control systems, all working and optimized together producing 80 percent fewer emissions of nitrogen oxides (NOx) and particulate matter (PM) than those systems produced just a decade ago.

As a result, communities and government agencies across the country- including the State of California- have embraced clean diesel technology as a solution to reducing emissions.

In 2003, the Diesel Technology Forum commissioned a sweeping report, "Diesel Technology and the California Economy." The report, developed by renowned economic research firm M3, highlighted the crucial role diesel technology plays in key segments of the California economy, including the state's massive agricultural sector.
