Comment submitted by Clean Air for the Long Haul (the Cohort)

Summary: WE ACT for Environmental Justice, representing the Clean Air for the Long Haul and the Environmental Justice Leadership Forum, opposes the proposed delay of the Tier 4 vehicle emissions standards. They argue that the delay to the 2024 standards (reverting to 2014 Tier 3 standards) disproportionately harms low-income communities and people of color by postponing critical public health benefits and ignoring the real-world health costs of continued pollution.
