McDonald's

Want less guilt with your burger? McDonald’s is working on it. The fast-food powerhouse has committed to reducing greenhouse gases related to its offices, restaurants, and supply chain—promising, by 2030, to cut that output by about a third from 2015 levels. The environmental impact would be massive: the equivalent of taking 32 million cars off the road for a year. It’s also a symbolically important move; environmental advocacy organizations say McDonald’s is the first restaurant group to set such a specific science-based target for reducing emissions.

To reach its goal, the company is doing everything from using LED lights to installing more energy-efficient appliances in its kitchens. And by 2025, all of its customer packaging will come from renewable, recycled, or certified-sustainable sources, and the company’s goal is to recycle it all in its own restaurants.
