SmartWay Transport

The SmartWay Transport Partnership is a voluntary collaboration between EPA and the freight industry to conserve fuel, reduce emissions, and improve transportation supply chain efficiency. SmartWay "makes the business case" for how companies shipping products, and the carriers that move those products, can improve their environmental profile while saving money and time.

Companies join the SmartWay Transport Partnership for a 3 year period, and begin by analyzing the efficiency of their operations using SmartWay software. EPA helps partners set individualized goals and select the right strategies to achieve them. Fleets choose from a wide variety of strategies to minimize idle time, reduce rolling resistance, improve aerodynamics, refine logistics and train drivers. Shippers participate by increasing the proportion of their product carried by the most efficient SmartWay carrier partners, choosing the most efficient modes, and improving freight logistics. Partners benchmark their operations, track their savings, and report yearly to EPA. Partners' SmartWay scores can qualify them to use the logo and receive other forms of recognition, including awards.

SmartWay partners now number close to 3000, including most of the biggest trucking companies and most visible shippers. But SmartWay is not only for huge companies—many smaller carriers and regionally-known shippers participate. SmartWay fact sheets and case studies showcase successful fuel-saving strategies. EPA is working with other countries to develop compatible freight efficiency programs that will enable international shippers to streamline their entire supply chain. SmartWay also specs fuel-efficient truck and trailer models, verifies fuel-saving technology, and sets up financing programs.

EPA New England is active in SmartWay, supporting existing partners, signing on new partners, and promoting efficient freight technologies, strategies and infrastructure.  Four NE-based SmartWay partners have received regional Environmental Merit Awards.  For more information, see the SmartWay website or contact Abby Swaine ( or 617-918-1841) at EPA New England.

Idling Enforcement

All six New England states have anti-idling regulations. The Connecticut, Massachusetts and Rhode Island regulations are part of state implementation plans. State regulations that are part of state implementation plans are federally enforceable. This means that EPA, as well as the State, has the authority to enforce these laws. EPA has taken enforcement action against fleets in Connecticut, Massachusetts and RI for alleged violations of the anti-idling regulations in those states. The press page of this site contains specific information about these actions.

Compliance Assistance

EPA NE conducts compliance assistance to encourage fleet and facility operators to comply with New England states' idling limits. We focus our compliance assistance efforts on states where EPA has enforcement authority trade associations, and fleets and locations of special concern. We also respond to complaints and inquiries from citizens and individual fleets/facilities. In addressing an issue, we seek to address the root of the idling problem, and to apply SmartWay fuel-saving technologies and strategies wherever possible.

To report or inquire about excessive idling in a specific location, we encourage you to first contact your state or local environmental agency:


Connecticut DEP – Air Quality Complaint Line at 860-424–3436


Maine DEP – Air Quality Bureau at 207-287-2437


City of Boston – Air Pollution Control Commission at 617-635-3850 or Massachusetts DEP – Regional Offices or call the general complaint line at 617-556-1000 or 1-800-VIOLATE

New Hampshire

New Hampshire DES – Air Resources Division at 603-271-1370 or 1-800-498-6868

Rhode Island

Rhode Island DEM – Office of Air Resources at 401-222-2808 or 800-752-8088
