BART's Environmental Credentials

Celebrate Earth Day by helping keep our sky blue

As we celebrate Earth Day this April, we can all do our part to save energy and protect the environment. An easy and inexpensive way to start is by riding BART.

Fast, Efficient, Energized

A typical car gets about 21 miles per gallon. During peak hours BART is 12 times more efficient on passenger miles per gallon basis than a standard occupant vehicle. A BART rider gets the equivalent of 249 miles per gallon. Not even the most fuel efficient hybrid can match that!

BART is 5 to 6 times more efficient during the high occupancy peak hour than the most popular hybrid vehicle.


BART Trains: Conserving Energy Mile after Mile

BART is the USA’S cleanest transit system emitting fewer pounds of CO2 per passenger mile than any other transit system. It is 100% electric and over half of that power comes from clean, hydro and renewable energy sources.
BART trains convert their kinetic energy of motion into electrical energy as the trains slow down. The energy regenerated during the process is returned to the power distribution system where it is then used by other trains.

Fast, Efficient, Energized

We know you love fresh air. So do the people at BART. Every weekday, BART riders save 280,000 gallons of gas and keep 4,900,000 pounds of CO2 out of our environment.

A typical BART trip is 14.4 miles. Just one commuter using BART each weekday saves over 300 gallons of gas and 6,277 pounds of CO2 in a year.

Driven by the Sun
BART is using energy from a 2.0 megawatt solar farm in the Central Valley. Future BART projects will incorporate solar energy, such as the MacArthur and Walnut Creek Transit Villages.

Counting Every Drop
BART recaptures 90% of train wash water then uses it to clean other trains. During droughts, BART reduces train washing cycles from every four days to every eight.

Thank you, BART riders, for doing you're part to help keep our Bay Area sky blue.
