A prominent climate group accused the McDonald\u0026#039;s corporation of another greenwashing stunt on Monday after the burger giant announced it would cut global greenhouse gas emissions to net-zero by 2050.\r\n\r\n\u0026nbsp;\r\n\r\n\u0022If McDonald\u0026#039;s changed its menu immediately it would make a big difference but waiting until 2050 is insufficient to avoid climate catastrophe.\u0022\r\n\r\n\u0022This is another stunt in a long line of greenwashing trends from McDonalds,\u0022 said Jennifer Molidor, senior food campaigner at the Center for Biological Diversity, in a statement. \u0022Net zero is not a climate solution, it\u0026#039;s an accounting trick. The company\u0026#039;s beef footprint alone produces more than 22 million metric tons of greenhouse gases annually. If McDonald\u0026#039;s changed its menu immediately it would make a big difference but waiting until 2050 is insufficient to avoid climate catastrophe. We don\u0026#039;t have 30 more years to get this right.\u0022\r\n\r\n\u0026nbsp;\r\n\r\nThe company\u0026#039;s 2050 net-zero target includes everything from its beef production to the light bulbs in its restaurants.\r\n\r\n\u0026nbsp;\r\n\r\nThe fast-food chain also revealed it is working with the nonprofit Science Based Targets initiative (SBTi) to improve its existing climate targets and aims to lower total emissions by about a third for both its suppliers and its nearly 40,000 company-run and franchised restaurants around the world by 2030.\r\n\r\n\u0026nbsp;\r\n\r\n\u0022We\u0026#039;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,\u0022 McDonald\u0026#039;s chief sustainability officer Jenny McColloch told Reuters in an interview.\r\n\r\n\u0026nbsp;\r\n\r\nMcDonald\u0026#039;s is one of the largest beef purchasers in the world―and the vast majority of its total emissions are produced by its supply chain, which includes beef, chicken, dairy, and other proteins.\r\n\r\n\u0026nbsp;\r\n\r\nThe company\u0026#039;s announcement comes as environmentalists continue to warn about the dire impacts of animal agriculture, including a September report published in Nature Food that detailed how global food production accounts for more than a third of all greenhouse gas emissions, with meat and dairy responsible for twice as much planet-heating carbon pollution as plant-based foods.\r\n\r\n\u0026nbsp;\r\n\r\nAs reported in Common Dreams, according to the study, beef production contributes 25% of all food-based greenhouse gas emissions—by far the biggest culprit, followed by cow\u0026#039;s milk, pork, and chicken.\r\n\r\n\u0026nbsp;\r\n\r\nA 2019 special report on climate change and land by the Intergovernmental Panel on Climate Change (IPCC) recommended plant-based diets as a major opportunity for mitigating and adapting to the climate crisis―and included a policy recommendation to reduce meat consumption.
