How do we protect our environment for future generations?

For freight railroads, the answer is by innovating technologies, investing in equipment and pioneering new ways of efficiently running our operations to help mitigate climate change. With a private freight rail network that stretches nearly 140,000 miles coast-to-coast, every improvement along the way means a big difference for America’s carbon footprint. Here are just some of the ways freight rail is delivering a more sustainable future for America.


Reducing Idling

Freight rail has a much smaller carbon footprint than other transportation modes. Despite moving roughly one third of U.S. exports and accounting for 40% or more of long-distance freight volume (measured by ton-miles), railroads account for just 2.1% of emissions from transportation-related sources, according to data from the U.S. Environmental Protection Agency. Technology like innovative “stop-start” idling-reduction systems that automatically power down idling locomotives is just one way railroads keep emissions down.

Maximizing Every Gallon

Steel wheels on steel rail is an inherently efficient way to move goods, but that doesn’t stop America’s freight railroads from finding ways to do more with less. Railroads use fuel management systems —  software that provides real-time recommendations to engineers on how to drive the locomotive in the most efficient way — to maximize fuel efficiency.

When multiple locomotives are used to operate a single train, advanced technology adjusts the power setting on each locomotive individually to optimize efficiency and reduce fuel waste while maintaining a consistent speed. Taken together, these and other efforts allow railroads to move one ton of freight an average of more than 470 miles on a single gallon of fuel, making trains four times more fuel efficient than trucks.

Making Freight Yards More Environmentally Friendly

The rail industry’s commitment to making its systems more environmentally friendly extends well beyond trains and tracks. Traditionally, cranes used to move cargo on and off freight cars used diesel fuel. Recently, though, the use of electric cranes that produce zero greenhouse gas emissions has increased.

Redesigning Railcars

Thanks to improved freight car design and other efforts, in 2019 the average freight train carried 3,667 tons, up from 2,923 tons in 2000. By moving more freight without increasing fuel use, the redesigned railcars have made freight rail even more sustainable.

Relieving Highway Congestion

A single freight train can take several hundred trucks off the nation’s highways — helping motorists and communities breathe easier. In fact, AAR analyzed data and found that if 25% of the truck traffic moving at least 750 miles went by rail instead, annual greenhouse gas emissions would fall by approximately 13.1 million tons. If 50% of the truck traffic moving at least 750 miles went by rail instead, greenhouse gas emissions would fall by approximately 26.2 million tons.

And, with taxes and fees paid by commercial trucks falling far short of covering the cost of the highway damage they cause, privately-owned freight railroads — which spend approximately $25 billion in private capital annually on their network — relieve taxpayer burden, as well.

A cleaner environment and less congested roads are important priorities for our nation. And, with the U.S. Department of Transportation expecting total freight demand to grow 30% by 2040, moving more freight by rail is a choice everyone can feel good about.
