The world’s biggest fast-food chain has pledged to cut global greenhouse gas emissions to net zero by 2050

McDonald’s Corporation set the target on Monday which will include the beef in its burgers to the light bulbs in its restaurants.

The burger chain also said it was working with the nonprofit Science Based Targets initiative to revamp its existing climate change targets.

The initiative aims to lower absolute emissions by about a third for both its suppliers and its nearly 40,000 company-run and franchised restaurants around the world by 2030.

“We’re trying to send a signal to our partners, to our investors, to our suppliers, to other brands in the global community, to policymakers, that we share that vision for 2050,”

McDonald’s told Reuters.

United Nations scientists say the world’s net emissions must fall to zero by 2050 to limit the rise in global temperatures to no more than 1.5 degrees Celsius versus pre-industrial levels.
