Dunkin' Donuts is going green. Dunkin' announced yesterday, that by 2020, they will no longer use polystyrene foam cups. Instead, they'll use a double-walled paper cup.

Their website says the move is just another part of their commitment to eliminate artificial dyes from menus, to build new, more energy-efficient restaurants, and partner with the Rainforest Alliance to source certified coffee.

I think we should all be happy that New England's favorite coffee place would be so environmentally responsible, but what do you think of Dunkin's plans to change the cups?
