About the Northeast Diesel Collaborative

The Northeast Diesel Collaborative (NEDC) is a regionally coordinated initiative to reduce diesel emissions, improve public health, and promote clean diesel technology. The Collaborative brings together the collective resources and expertise of several state environmental agencies, EPA regional offices, and private sector companies to address the existing fleet of diesel-powered vehicles and equipment.

Where We Work

Through innovative projects, voluntary measures, and mandatory programs, the Collaborative and its partners target the primary sectors contributing to diesel emissions in the Northeast, Puerto Rico, and the US Virgin Islands:

  • Municipal (school buses, refuse haulers, and other public works vehicles)
  • Transit (transit buses and commuter locomotives)
  • Ports/Authorities (ferries, tugboats, large ocean-going vessels, and port vehicles and equipment)
  • Construction (cranes, pavers, excavators, and front loaders)
  • Freight (trucks, locomotives and locomotive switchers)

NEDC Strategies and Activities

NEDC Priorities
The NEDC Steering Committee and Advisory Subcommittee establish a set of priorities that the Collaborative agrees to focus on for the coming years. Please follow this link to access the NEDC priorities for 2016/2017.

We work at the local and regional levels to:

  • Educate the public, lawmakers, and public and private fleet operators about the importance of and strategies for reducing diesel emissions
  • Integrate and expand existing programs
  • Create new partnerships, programs, and other measures to reduce emissions
  • Demonstrate new technologies and expand the use of proven technologies
  • Improve data on emission and fleet inventories as well as exposure and health effects

Specific activities include:

  • Retrofit, retire, and replace older engines
  • Promote idling alternatives for truckers, such as truck stop electrification and auxiliary power units
  • Work with states on enforceable measures to reduce idling
  • Promote use of clean diesel technologies in contract specifications
  • Promote cleaner fuels
  • Create educational opportunities and materials for key sectors and stakeholders
  • Measure and assess program effectiveness

Who We Are

Northeast Diesel Collaborative members include:

  • EPA Region 1 (Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut)
  • EPA Region 2 (New York, New Jersey, Puerto Rico, and the US Virgin Islands)
  • The environmental agencies of the 8 northeastern states and 2 Caribbean Territories
  • NESCAUM (Northeast States for Coordinated Air Use Management)
  • Members of the Ports & Goods Movement, Clean Construction, Funding, and Strategic Planning Work Groups, represented by multiple sectors

NEDC Steering Committee & Advisory Subcommittee

The Steering Committee, consisting of management staff from the EPA Regional Offices, the diesel emissions reduction program managers within the state and territorial air quality agencies, and designated NESCAUM staff, is the goal-setting body of the NEDC. The NESCAUM Board of Directors plus the Air Program leadership from EPA Regions 1 and 2 oversee the Steering Committee and ultimately ratify the policies and goals of the NEDC.
