Many businesses are all-in as well, rarely missing an opportunity to tout their green credentials. Max, a popular Swedish burger chain, recently introduced five new vegetarian dishes to reduce their carbon footprint, and instead of calorie counts, the restaurant labels each item on the menu with the CO2 emissions generated. (A Grand Deluxe Cheese ’n’ Bacon Burger will saddle the climate with 3.1 kilos of CO2, whereas a fish burger comes in at a bargain 0.2 kilos.)
