Clean diesel grants

Transportation is the largest source of climate pollution in Washington, accounting for nearly half of total greenhouse gas emissions. Diesel exhaust is responsible for 70 percent of Washington’s airborne cancer risk. The Governor and Legislature are spearheading policies and initiatives to address climate change and improve public health by accelerating the transition from fossil fuels to a zero emission transportation system. Clean diesel grants will reduce greenhouse gases and protect our children and those most affected by toxic diesel emissions. The program’s primary objective is to electrify school buses, but the program will also support idle reduction and other diesel equipment engine replacements.
