EAST RUTHERFORD, N.J. - The National Football League is hoping its first outdoor, cold-weather Super Bowl is also its greenest.
Since the mid-1990s, the league has been trying to gradually reduce the carbon footprint left behind by the Big Game. For next Sunday's game at MetLife Stadium, it has undertaken a host of initiatives.
Thousands of trees have been planted to offset carbon emissions, and the league sponsored recycling events that collected several tons of used computers, cellphones and other gadgets.
On game day, about seven or eight tons of food waste will be composted at MetLife Stadium, and unused food will be donated to food pantries.
Generators on-site and at New York's Super Bowl Boulevard at Times Square will be powered by a biodiesel fuel mix processed from cooking oil waste.
