Public Fleet ZEV Requirements

LD 1579 (2022) – By 2025: 50% of the State’s new light-duty vehicles (LDVs) purchased or leased be plug-in hybrid or zero-emission vehicles | By 2030: 100% of state-purchased or leased LDVs must be plug-in hybrid or ZEVs

Equity

Environmental Justice Community Designation

Mandate Source

LD 2018 (2022)

Definition

“Frontline communities” means those people and communities that experience the consequences of climate change first and to a greater degree than other people and communities.

The Department of Environmental Protection must also define “environmental justice populations,” taking into consideration, at a minimum, median household income, race, ethnicity, and English language proficiency.

Include race? Yes | Include income? Yes | Include pollution burden? No
