The Earth Day Report:
Every Earthday, April 22nd, the New York Metropolitan Transportation Authority(disclaimer: I work as the MTA’s Director of Sustainability Initiatives), comes out with a sustainability report. This year we focused on carbon. Turns out every MTA trip prevents 10.4 pounds of greenhouse gas emissions from entering the atmosphere. In the net that adds up to 17 million metric tons. Very likely, making the MTA the single largest carbon-cutter in the United States.
Thats what good public transportion does!
