How far are you willing to take your effort to stem climate change and help the planet? The Bon Appetit Management Company has created the first Low Carbon Diet Calculator, which evaluates everything you put in your mouth based on its carbon footprint. The idea is to quantify how your food fuel is impacting the earth. According to Bon Appetit, food is responsible for a third of global greenhouse gasses. So it might be worth it to curb your carbon intake.
