75 Mayors Urge President Biden to Finalize the Strongest Possible EPA Heavy Duty Vehicle Rules

As members of Climate Mayors, a bipartisan network of over 350 Mayors committed to climate action and reducing greenhouse gas (GHG) emissions in our cities, we write to urge this Administration to finalize the Environmental Protection Agency’s (EPA) strongest proposed rule for the GHG Emissions Standards for Heavy-Duty Vehicles – Phase 3 rule (HDV rule).

Our coalition believes that finalizing the EPA’s HDV rule will protect public health, address the climate crisis, and align with the heavy-duty vehicle industry’s commitment to transition to zero-emission vehicles. We know that transitioning from Internal Combustion Engine (ICE) vehicles to Electric Vehicles (EVs) results in cleaner air and positive public health benefits from improved air quality, reduced carbon emissions, and financial savings in terms of fuel and maintenance costs. Additionally, the EPA forecasts that depending on the vehicle type, their proposed rule would lead to 25-50% of new sales of HD vehicles being zero-emission in 2032. We must meet the moment and accelerate our efforts to pave the way for sustainable and systemic change.
