Clean Corridors Meeting

Clean Corridors Meeting, November 3 and 4, 2016, Rensselaer Polytechnic Institute, Heffner Alumni House, 1301 Peoples Ave., Troy, New York 12180

Dear Partners,

On behalf of the Meeting Hosts, thank you for joining us at RPI in Troy, New York for the first-ever Clean Corridors Meeting on November 3 & 4. Over 160 participants from the Northeast and beyond came together to discuss opportunities to collaborate on developing clean, sustainable freight and passenger corridors. We had great representation across states, agencies, disciplines, and sectors. Panelists provided succinct and stimulating presentations on key perspectives & issues. Participants rolled up their sleeves and debated openly on how to make progress toward our common vision of providing the multi-faceted fueling, charging and layover infrastructure needed to reduce emissions, enhance energy security, and stimulate the adoption of clean vehicle technologies. Throughout the meeting, it was clear that partners want to continue this collaboration into 2017 and beyond.

We are finalizing the meeting notes, presentations, and photos and will make them available to you over the next two weeks. The Cadmus Group and Atlas Policy team will soon provide tools to support state Dots' efforts to plan and implement clean corridors. We will offer all meeting participants and stakeholders a webinar in December to review lessons learned and discuss next steps to move this initiative forward.

Clean Air Northeast Clean Freight Corridors Workgroup

The Clean Freight Corridors Workgroup promotes effective coordination across Northeastern states to plan for and develop clean freight corridors to advance high-efficiency, low-emission alternative transportation technologies across all modes.

2018 Clean Freight Corridors Workgroup Webinar: Northeast Opportunities for Alternative Fuel Corridors

On December 11th, the NEDC hosted a webinar highlighting opportunities in helping to grow a network of "alternative" (natural gas, propane, electric, fuel cell, hydrogen, etc) fueling stations for trucks and other medium/heavy -duty vehicles in the Northeast. The presentations and recorded audio of the webinar can be found below.

Federal Regulations

Regulations for Smog, Soot, and Other Air Pollution from Commercial Trucks & Buses

Clean Diesel Trucks and Buses Rule: The Clean Diesel Trucks and Buses Rule sets more stringent emissions standards for on-road diesel vehicles beginning with those manufactured in 2007. The Rule will be fully implemented by 2010. The rules require clean diesel fuel with a sulfur content capped at 15 parts per million and the use of advanced emission control technology. Exhaust emissions from these vehicles will decrease by more than 90 percent. While cleaner fuel will reduce emissions from all diesel vehicles, the new emission standards only affect newly manufactured on-road diesel vehicles, so the full benefits of these regulations will not be realized for years to come.

Control of Air Pollution from New Motor Vehicles: Heavy Duty Engine and Vehicle Standards: EPA adopted this rule in December 2022 which sets stronger emissions standards to further reduce air pollution from nitrogen-oxide (NOx) emissions from heavy-duty vehicles and engines starting in model year 2027. The rule sets new, more stringent emissions standards that cover a wider range of heavy-duty engine operating conditions compared to today’s standards, and it requires these more stringent emissions standards to be met for a longer period of time of when these engines operate on the road.

Emissions Standards for Locomotives: In 2008, EPA finalized a new set of more stringent emission limits for locomotives, to be phased in over the next decade, which will result in locomotive engines that are 90% cleaner than today. This new rule also requires remanufactured locomotive engines to meet more stringent emissions standards than they were required to meet at the time of original manufacture.

State and Local Regulations

Six of the eight Northeast states have anti-idling regulations:

EPA NE conducts compliance assistance to encourage fleet and facility operators to comply with New England states' idling limits.

The American Transportation Research Institute publishes a compendium of idling regulations by state and updates it regularly.

FHWA Talking Freight Seminar Series

The U.S. Department of Transportation Federal Highway Administration hosts monthly net-conference seminars to provide a convenient and no-cost way for transportation practitioners to broaden their freight knowledge base and develop new skills to help them do their jobs better. Visit to register for upcoming sessions and see/hear recordings of previous seminars.

Freight transportation accounts for approximately 9% of total greenhouse gas (GHG) emissions in the United States. This report for the US Department of Transportation surveys 59 potential best practices for reducing energy use and GHG emissions in freight transportation.

Smartway Transport Partnership

The SmartWaySM Transport Partnership is a voluntary collaboration between US EPA and the freight industry designed to conserve fuel while significantly reducing greenhouse gases and other air pollutants. Companies that provide or hire freight delivery and logistics services can become SmartWay Transport partners. EPA helps partners calculate their current environmental performance, set improvement goals, understand fuel-saving strategies and technologies, calculate cost savings, and win industry and public recognition. SmartWay also verifies the performance of fuel-saving technologies, certifies trucks and trailers with energy-saving features, and offers a variety of financing opportunities.

Currently over 2000 shippers, carriers, logistics providers, and affiliates participate in the Partnership, including hundreds in Canada. SmartWay is quickly expanding its international reach and developing new tools to help shippers analyze their carbon reduction options more accurately within and across all modes in their "supply chain" (truck, rail, port drayage, marine, etc.).

EPA Regions 1 and 2 are active in SmartWay, both recruiting and supporting partners. New in 2009 are cooperative agreements, one in both Regions 1 and 2, with Cascade Sierra Solutions to provide rebates for truck & trailer upgrades.
