Zero Emission in Freight:

Heavy Duty Trucks (HDT)

In order to address the impacts from freight related trucking MFN demands comprehensive regulations that center the needs of frontline workers and communities. Without these critical regulations and resources, our communities will continue to suffer from the public health and environmental damages caused by the heavy duty truck sector.

On October 26, 2021 MFN submitted numerous recommendations to EPA in order to address the environmental and public health impacts from the freight transportation system. Among these are specific demands relating to heavy duty trucks. 

  • Transition to zero-emission trucks and buses, by setting stringent emissions standards and zero-emission sales mandates.
  • Require that all new trucks have zero emissions beginning in 2035.
  • Retire all combustion trucks on or before 2045.
  • Consider environmental justice impacts and priorities “from source to tailpipe to grave.”
  • Not promote false solutions, (e.g., carbon trading and/or“greenwashed” energy that comes from non-renewable and heavy-polluting sources such as natural gas, biomass, etc.)

The Environmental Protection Agency’s Heavy Duty Truck Rule

Beginning our Zero Emission in Freight campaign MFN members, allies, and supporters are organizing to address the recently released Environmental Protection Agency (EPA) proposed Heavy Duty Truck Rule.

MFN’s response to the HDT Rule is that the current draft:

1. DOES NOT ensure emission reductions for environmental justice communities.

2. DOES NOT require the deployment of zero emission heavy duty trucks.

3. Ultimately leaves significant emissions reductions and zero emission requirements to future rules.

Talking Points in Response to the EPA’s Heavy Duty Truck Rule

Use these messaging points to guide your content creation and communications around the Heavy Duty Truck Rule (HDT).

The EPA’s heavy duty truck rule fails our EJ communities. This proposal ignores the longstanding demands from EJ communities to move the most protective solutions that will require air pollution reductions in EJ communities.

EPA’s proposed rule punts meaningful action into the uncertain future, yet again delaying justice for communities of color and frontline communities and perpetuating environmental racism.

Heavy Duty Trucks contribute to the worsening of the public health, environmental, and climate crisis. With this current rule the Biden Administration is falling short of their commitments to prioritize EJ and address the climate crisis. EJ communities cannot wait. We need strong regulations now, justice delayed is justice denied.

Environmental Justice communities are choking to death from the pollution from heavy duty trucks. The Biden Administration needs to prioritize community health over corporate wealth and at minimum require a just transition towards zero emission trucks.

We want to see a just transition towards zero emissions across the freight sector. For jobs to be truly green and good jobs they must provide economic and health benefits for the workers and the adjacent communities. For EJ communities they are often 1 in the same.

The EPA along with the administration should be proposing solutions aimed at phasing out our dependency on deadly diesel. We will not accept partial solutions that leave us further burdened by pollution for decades to come.

Zero Emissions must mean zero – not near zero.
