Medium- and Heavy-Duty Zero Emission Vehicles

Multi-State Memorandum of Understanding (MHD ZEV MOU)

DEC held a Stakeholder Outreach webinar "Consideration to Revise 6 NYCRR Part 218 to Incorporate California's Advanced Clean Trucks, Heavy-Duty Low NOx Omnibus, and Phase 2 Greenhouse Gas Standards" on February 17, 2021. View the Stakeholder Outreach webinar slides (PDF)

DEC held a kick off meeting on October 21, 2020, to discuss the MHD ZEV MOU and Action Plan development. The Action Plan will identify existing barriers and propose solutions to support widespread adoption of MHD ZEVs. View the MHD ZEV MOU kick off meeting slides (PDF)

On July 14, 2020, Governor Andrew Cuomo, along with the governors from 14 states and the Mayor of Washington D.C., signed a joint memorandum of understanding (leaves DEC website) committing to work collaboratively to advance and accelerate the market for electric medium- and heavy-duty (MHD) vehicles. MHD vehicles include large pickup trucks, vans, delivery trucks, box trucks, school and transit buses, and long-haul delivery trucks. The mutual goal of the signatories is to ensure that 100 percent of all new MHD vehicle sales will be zero emission vehicles (ZEV) by 2050 with an interim target of 30 percent MHD ZEV sales by 2030. The MOU comes at an important transition point for the motor vehicle industry as investment in ZEV technology for the MHD sector is developing beyond a nascent industry.

DEC's Commissioner Basil Seggos noted, "Without federal leadership, addressing the climate crisis requires states to work together to take action to reduce greenhouse gas emissions from all sources. Reducing air pollution from medium- and heavy-duty vehicles will result in cleaner air for our communities-including low-income neighborhoods and communities of color that are often disproportionately impacted by environmental pollution. Today's announcement bolsters New York's ongoing efforts to electrify the transportation sector and reduce climate pollution, helping to realize our ambitious emissions reduction goals and grow a powerful green economy to benefit all communities."

The MHD ZEV MOU will support the increased electrification of NY's transportation system, reducing the greenhouse gas (GHG) emissions that contribute to climate change that threatens NY's people and environment. Governor Cuomo established nation-leading GHG emission-reduction goals of 40% from 1990 levels by 2030 and 80% by 2050 (leaves DEC website). Meeting these aggressive goals requires a sustained transformation of NY's economy from fossil fuels to an economy powered by carbon emission-free renewable energy sources.

MHD ZEVs and Greenhouse Gas Emissions

The transportation sector is NYS' largest source of GHG and NOx emissions with medium- and heavy-duty vehicles having a disproportionate share compared to other mobile sources. Accelerating the move to zero emission trucks and buses is an essential step to achieve the deep economy-wide emission reductions needed to avoid the worst consequences of climate change and protect the health of millions of Americans. While trucks and buses only account for 4 percent of vehicles on the road, they are responsible for nearly 25 percent of total transportation sector GHG emissions. Emissions from trucks are the fastest growing source of GHGs, and the number of truck miles traveled on the nation's roads is forecast to continue to grow significantly in the coming decades. Clean trucks and buses promise to deliver widespread health benefits, particularly in disproportionately impacted low-income communities of color, and environmental justice areas often located near major trucking corridors, ports, and distribution hubs.

Decarbonizing NYS' Transportation Systems

NYS has already completed several critical steps to transform our existing transportation system by supporting cleaner and electric transportation through these programs.

In the near future, MHD ZEV fleets will be able to take advantage of fleet assessment services offered to be developed by NYS' six major investor-owned utilities.

MHD ZEV Action Plan

The signatories of the MHD ZEV MOU have committed to drafting an Action Plan by early 2021. The Multi-State ZEV Task Force (leaves DEC website), coordinated by the Northeast States for Coordinated Air Use Management (NESCAUM), will develop the Action Plan (leaves DEC website) to identify barriers and propose solutions to support widespread adoption of zero emission MHDs and give other considerations outlined in the MOU.

A similar action plan was completed for the Light-Duty Zero Emission Vehicle MOU (leaves DEC website) signed in 2013. The ZEV Task Force completed a light-duty Multi-State ZEV Action Plan in 2014 and a 2018-2021 Multi-State ZEV Action Plan Update in 2018.

In developing the MHD Action Plan, the Multi-State Task Force will consult with, and solicit input from, key partners and stakeholders. To support this effort, DEC has developed an MHD ZEV Action Plan stakeholder list that includes NYS agencies and authorities, major private fleets, non-governmental organizations, environmental justice and advocacy groups, NYS trucking associations and electric utilities.

What's Next

DEC will accept input as the Multi-State ZEV Task Force develops the MHD ZEV Action Plan. Comments and suggestions can be submitted to Please include your name and contact information.

This webpage will be updated periodically and will include a draft MHD ZEV Action Plan, when available.
