To celebrate Earth Day, MTA’s green MetroCards on sale today last weekend

To celebrate Earth Day, as I noted last week, the MTA has released a limited number of green MetroCards with environmental fun facts on the back. The MTA says that these MetroCards, limited to five million in number, were first put on sale today, but I found one at the 96th St. stop on the West Side IRT on Saturday. My card tells me that “public transportation cuts fuel consumption by 1.4 billion gallons every day.” [MTA HQ]
