California’s Clean Diesel Program


Two highly successful air quality programs designed to lower emissions from older diesel engines were included in a major legislative package signed into law by Californian Governor Jerry Brown on Sept. 28, 2013.

“The $2 billion ten-year package included continued funding for two major California clean diesel programs – the Carl Moyer Memorial Air Quality Standards Attainment Program and AB 923 which supports local air district program to reduce diesel emissions,” said Ezra Finkin, Policy Director of the Diesel Technology Forum.

“Californians can rightly boast about being the nation’s leader on many fronts, but the fight against air pollution, and putting financial muscle behind the rhetoric, is among the most impressive,” Finkin said. “We congratulate Gov. Brown and the bill’s sponsors Assemblymember Henry T. Perea, Assemblymember Nancy Skinner and Sen. Fran Pavley.”

The Carl Moyer Memorial Air Quality Standards Attainment Program was first implemented in 1998 and has replaced or upgraded 48,000 diesel engines resulting in a reduction of 146,000 tons of ozone forming compounds and 6,000 tons of particulate matter or soot. AB 8, signed by Governor Brown, extends funding for the program through 2023.
