... The biggest contributors to pockets of unhealthy air across the state are the planes, trains, trucks and ships that move goods around, according to the California Air Resources Board. Heavy-duty trucks spew out 25 percent of diesel particulate pollution statewide, and produce about 8 percent of the state’s total greenhouse gases.
To tackle that tailpipe pollution, California’s clean air enforcers have proposed a rule that calls for major truck manufacturers to sell zero-emission vehicles in the state. Called the Advanced Clean Trucks regulation, it also asks major corporations and government agencies to report information about how they use their trucks — laying the groundwork for future rules to drive business toward clean truck companies.
As written, a Union of Concerned Scientists analysis estimates the rule could put 75,000 clean trucks on the road by 2030 — or about 4 percent of the state’s trucks.
A handful of California legislators have joined the call for a tougher rule. At the end of November, Democratic assemblymembers Eloise Gómez Reyes, Phil Ting, Luz Rivas, and Marc Berman joined Democratic senators Ben Allen and Bob Wieckowski in a letter to air board chair Mary Nichols that said the proposed rule “falls woefully short of an impactful goal.”
In their letter, the lawmakers said: “Improving local air quality and reducing California’s contribution to global warming will require more than 4 percent of trucks to be zero-emission by 2030.”
Legislators are paying attention, too. “The hope had been that the air board would provide the leadership necessary,” said San Francisco Democratic Assemblymember Phil Ting. “But obviously if they aren’t able to then we’ll definitely consider legislative action.”
