The latest developments in the food industry show how fast the world is moving forward in countering climate change. Just this week, the global food chain giant McDonald’s announced that it is planning to cut its emissions intensity by 31%, across its supply chain, by 2030. That’s a big deal. It’s the first global restaurant company in the world to set a science-based target to reduce greenhouse gas emissions. If McDonald’s can lead on this, so should the United States.
