California Natural Gas Vehicle Coalition v. California Air Resources Board

The California Natural Gas Vehicle Coalition filed a lawsuit in California Superior Court challenging the California Air Resources Board’s (CARB’s) approval of the Advanced Clean Truck Regulation, which would require that manufacturers sell an increasing percentage of medium- and heavy-duty zero-emissions vehicles (ZEVs). The Coalition alleged that CARB violated the California Environmental Quality Act and the California Administrative Procedure Act, including by failing to consider reasonable alternatives such as a plan that would include both ZEVs and low NOx trucks. The petitioners said such a plan would achieve immediate and long-term reductions in greenhouse gas and NOx emissions in the heavy-duty transportation sector.
