Here in the United States, public transportation saves 37 million metric tons of carbon dioxide and 4.2 billion gallons of gasoline annually, according to the American Public Transportation Association. Though a greener option than personal vehicles by far, transit agencies still use large amounts of energy, and produce their fair share of waste, in the course of operations.
You’ve already read what we here at Metro are doing to ensure a more sustainable, energy-efficient system today and in the future. With Earth Day as our impetus, we decided to take a look at how other transit agencies across the country are going green. Below, a few examples:

The Massachusetts Bay Transportation Authority has hosted fifteen community recycling events at their train stations between fall 2012 and spring 2014 to help Bostonians properly dispose of land-banned items such as TVs and other electronics. MBTA’s stations also feature newspaper recycling containers that collected over 700,000 lbs in their first three months of installation.

Metropolitan Atlanta Rapid Transit Authority‘s Laredo Bus Facility in Decatur boasts the largest solar PV installation in Georgia, with 4,888 panels generating 1.2MW of green power.
The South Eastern Pennsylvania Transit Authority said its wayside energy storage system was the “first in the world” of its kind when installation began in summer 2012. Several large, sheltered batteries allow SEPTA to capture, store, and reuse its trains’ regenerative braking energy. Extra power can be sold back to the electrical grid to insure demand and stability.
