SAN FRANCISCO, Calif. — The Bay Area Goods Movement Program will provide more than $35 million this year for public and private entities to make their trucks, trains and harbor vehicles cleaner.

The program, a collaboration between the Bay Area Air Quality Management District and Air Resources Board, is accepting applications for grants until August 15.

Grants are given to fund retrofits or replacements of engines and purchases of new equipment that reduce diesel emissions in advance of regulatory requirements.

The Air Resources Board will provide $140 million in bond funding for the program over the next four years.

"Emissions from aging heavy-duty engines are a major source of Bay Area air pollution," said Air District Executive Officer Jack Broadbent. "The Goods Movement Program helps owners invest in cleaner freight-moving equipment to protect the air and reduce greenhouse gas emissions."
