 Legislation aiming to electrify all passenger and light-duty vehicles in the state fleet clears its final legislative hurdle. State Senator Sarah McBride explains the bill aims to reduce the state's contribution to greenhouse gas emissions, and it sets benchmarks as to how quickly the fleet needs to be converted to zero-emission vehicles, or ZEVs. HB 9 sets benchmarks to achieve 100% ZEV by 2040 as follows. 15% by 2026, 25% by 2029.
