California Withdraws Stricter Emissions Requests

California has withdrawn its requests for federal approval of stricter emissions rules for diesel-powered trucks and locomotives, anticipating pushback from the incoming Trump administration. The California Air Resources Board (CARB) previously voted to phase out the sale of new diesel trucks by 2036 and to ban locomotives older than 23 years by 2030, but these initiatives faced significant opposition from the industry. CARB Chair Liane Randolph stated that the withdrawal was a necessary step given the uncertainty surrounding the new administration, which has historically opposed California's climate initiatives. Environmentalists criticized the decision, highlighting the health risks associated with diesel pollution. Although the board is evaluating future actions to address emissions, no specific plans were detailed. The EPA confirmed it would not take further action on the rules as proposed by CARB.
