WASHINGTON, D.C. – On Friday, several of the nation’s leading environmental organizations, including the Sierra Club, moved to intervene to defend California’s low-nitrogen oxide (NOx) Heavy-Duty Omnibus (HDO) waiver.
The low-NOx HDO program requires new combustion engine trucks and buses to progressively reduce toxic air pollution. The Biden administration’s EPA recently granted a waiver, and this program has been adopted by ten states.
On January 23, Sierra Club and other groups also intervened to protect the Advanced Clean Cars II (ACC II) waiver, which reduces pollution from cars by increasing the number of zero-emission vehicles automakers need to offer consumers. The standards ensure automakers will only sell zero-emission vehicles by 2035 in California, as well as twelve states plus DC that have adopted the program.
With the filing, Yassi Kavezade, senior advisor to Sierra Club’s Clean Transportation for All campaign, released the following statement:
“Making trucks cleaner should be a no-brainer. California and other clean truck states use these common-sense low-NOx standards to clean up dangerous air pollution from the dirtiest, heaviest vehicles on their roads. We stand with these states to defend their well-established authority to set standards for clean trucks.”
