Several Western Pennsylvania officials called Monday for a quick transition to electric vehicles and clean-energy generation.

Pittsburgh Mayor Ed Gainey, State Sen. Lindsey Williams and other advocates held a news conference to express support for proposed federal vehicle standards that the U.S. Environmental Protection Agency said would aim to “accelerate the ongoing transition to a clean-vehicles future and tackle the climate crisis.”

The officials also touted local efforts to begin moving to electric vehicle technology.

Gainey touted Pittsburgh’s efforts to transition its vehicle fleet to electric, and highlighted the city’s recent purchase of four fully electric trucks. The trucks, he said, can travel up to 320 miles on one $5 charge, which is environmentally friendly and cheaper than the city’s other trucks, which cost about $50 per fill-up at the pump.
