Can pepperoni pizza help save the planet? Pizza Hut Restaurants is betting on it. One of the world’s biggest restaurant chains, the brand has added plant-based pepperoni—pepperphoni—to its menus in England, Wales and Scotland. The company sees this move as a way to give diners a delicious new option while reducing its carbon footprint.Shifting diets away from so much beef, and toward more plants, is a win for the climate. Producing beef requires 20 times more land and emits 20 times more greenhouse gas emissions than producing common plant-based proteins.
