Public Transit Supports Cleaner Air

One of the most effective ways to support a cleaner, healthier environment is by increasing the use of public transportation and making it accessible to more people. We all share the benefits of cleaner air —even if we don’t use public transit personally.

It Starts with Carbon Reduction

All forms of public transportation are more energy efficient than cars, moving more people per mile per unit of emissions. Overall, public transportation reduces our nation’s carbon emissions by 37 million metric tons annually. On average, more than 11.5 million gallons of gas are saved every day because of public transportation.

Public Transit Spearheads Clean Technology

Modern rail vehicles are largely powered by electricity and generate little or no emissions. Many transit agencies also purchase clean renewable electricity to power their rail lines and operations. This in turn encourages utilities to develop more sources of renewable energy, which benefits electricity consumers across whole regions—even if they don’t use public transportation.

Buses provide the backbone of most public transit systems in the nation. Some buses still run on traditional fuels but many fleets now include electric buses, as well as combustion engine vehicles that use cleaner alternative fuels like compressed natural gas (CNG). Other buses are equipped with hybrid-diesel engines or run on biodiesel.

Investing in public transportation for every state will help us make faster progress in clearing our air, protecting our water, and reducing greenhouse gas emissions. Let’s make sure Congress hears this message.
