California Diesel Truck Rules

The California Air Resources Board (CARB) adopted two new truck rules in December, 2008 that will significantly reduce diesel fuel consumption and better protect public health and the environment. One rule, a first-of-its-kind regulation addressing truck global warming pollution, will significantly reduce heat-trapping emissions. The other rule, which addresses smog-forming and particulate pollution, will markedly improve California air quality, saving thousands of lives over the next decade.
