Proposition 1B, also known as the Goods Movement Emission Reduction Program, was approved in 2006 and has provided funding for projects that aim to reduce emissions. Prop 1B intends to reduce diesel air pollution from goods movement operations, which is broken down into two categories: heavy-duty trucks and transportation refrigeration units (TRU).
Emissions from diesel equipment, locomotives, and vehicles that will be regulated greatly impact the "health of communities located near ports, rail yards, distribution centers, and roads with high truck traffic." These emissions contribute to local and regional air pollution which is also the cause of the high regional ozone and fine particle levels harming millions of Californians today.
Prop 1B has guidelines and specifications relating to heavy-duty diesel trucks, locomotives and railyards, ships, cargo handling equipment, and more. These specifications outline recommending funding priorities for each appropriation and ways to evaluate projects that aim to reduce emissions.
