Environmental Impact

Short lines are proud to be part of the U.S. freight rail network – the most environmentally-friendly way to move freight over land.

Railroads account for roughly 40% of U.S. long- distance freight volume but account for just 2.1% of transportation-related emissions.* If 10% of the freight shipped today by the largest trucks were moved by rail, greenhouse gas emissions would fall more than 17 million tons annually or the equivalent of removing 3.35 million cars from the road. A ton of freight moving by rail instead of truck reduces greenhouse gas emissions by 75%.**

Already the leader in fuel-efficient surface transportation, the railroad industry is now making every effort to be a part of the solution to improving the environment, and the short line industry is all in on a variety of fronts.

Read ASLRRA’s November 19, 2021 letter to Secretary of Transportation Buttigieg, expressing support of the Administration’s Climate Action Plan.

Improving the Environmental Impact through Asset Upgrades, Technology and Behavior

Short lines are already efficient in the movement of freight from a fossil fuel-use standpoint. ASLRRA has joined the freight rail industry in supporting initiatives that further the reduction in environmental impact in a number of ways.

The rail industry is actively reducing its environmental impact through support of regulations such as the recent Federal Railroad Administration’s January 15, 2021, notice of proposed rulemaking to revise 49 C.F.R. Part 232 to address the use of electronic air brake slips (“eABS”) to track mechanical inspections and freight car mileage, which reduced the amount of time engines must spend idling during brake checks.

The industry is upgrading track which makes movement more efficient, and retro-fitting or replacing locomotives to improve emissions. The industry is finding ways to improve efficiency/reduce emissions by making changes in behavior of employees, and processes. The industry is adopting new technology that will further reduce its environmental impact.

Steps Taken to Further Reduce the Environmental Footprint of Rail Transportation:**

  • Fuel-efficient Locomotives: Acquiring and retrofitting thousands of new, more fuel-efficient locomotives that emit fewer criteria pollutants and GHGs over the past decade.
  • Operational Improvements: Carrying an average of 3,667 tons of freight per train in 2019, up 25% since 2000. By carrying more freight, railroads reduce unnecessary train and railcar movements, reducing fuel use.
  • Aerodynamics & Lubrication: Adopting operational fixes to reduce fuel use. For example, advances in lubrication techniques reduce friction, ultimately decreasing drag and saving fuel.
  • Anti-idling Tech: Installing idling-reduction technologies, such as stop-start systems that shut down a locomotive when it is not in use and restart it as needed.
  • Distributed Power: Expanding use of distributed power (positioning locomotives throughout the train) to reduce the total horsepower required for train movements.
  • Training: Training employees and contractors to help locomotive engineers and other personnel develop and implement best practices and improve awareness of fuel-efficient operations.



Railroad and supplier members of ASLRRA are encouraged to join the SmartWay program! Click for details on the benefits of participating and how to build your profile. Membership is FREE.


ASLRRA became an affiliate member of EPA’s SmartWay program in 2020. SmartWay helps companies advance supply-chain sustainability by measuring, benchmarking, and improving freight transportation efficiency. It offers tools short lines can use to communicate how shipping by rail can help customers meet their company’s environmental goals. Reducing a company’s carbon footprint is a growing imperative but isn’t easy - we believe that shippers will move from truck to more fuel-efficient rail if we can adequately demonstrate our real contribution to that goal. Unilever and Home Depot are but two high profile examples of major shippers that are now publicly talking about the environmental benefits of using rail.

Both railroad and supplier members of ASLRRA can participate in the SmartWay program.
