Last week, US Senator Alex Padilla (D-Calif.), Congresswoman Nanette Diaz Barragán (D-Calif.-44), Senator Cory Booker (D-N.J.), Congressman Donald McEachin (D-Va.-04), and Congresswoman Pramila Jayapal (D-Wash.-07) led 61 of their colleagues in both the US Senate and House of Representatives in sending a letter urging the Environmental Protection Agency (EPA) to finalize ambitious clean truck standards (earlier post) that reduce NOx and greenhouse gas emissions and include requirements for the sale of zero-emission trucks.
Updating the outdated NOx standards is a top priority and it is critical that this rule provide pollution reductions that are at least as protective as the reductions that are codified in California’s recent Heavy-Duty Omnibus and Advanced Clean Trucks rules. This means, at a minimum, EPA should meet or exceed California’s Heavy-Duty Omnibus program by setting a standard that achieves, by 2027, a greater than 90% reduction in NOx emissions from trucks that are sold today relative to 2010 standards. Having a unified national program will provide needed equity of reduced emissions across the country, reduced regulatory complexity, and reduce unnecessary costs of complying with two separate regulatory requirements.
At the same time, this rule must accelerate the adoption of zero-emission trucks by providing a clear signal for manufacturers to chart a path to eliminating tailpipe pollution. At a minimum, the federal government should require that all new trucks must have zero emissions beginning in 2035, with intermediate targets before then. In addition, after completing this Heavy-Duty rule in 2022, EPA should move quickly to advance additional policies to eliminate emissions from the freight sector to accelerate the retirement of all combustion trucks by 2045.—Letter to EPA Administrator Regan
There are currently more than 100 commercially available models of zero-emissions medium- and heavy-duty trucks and buses, with additional models expected each year.
