While companies selling imitation meat boast of the environmental benefits, some climate researchers say that the carbon footprint of those products are significantly higher than real plant-based diets.
In fact, a recent landmark report from the Intergovernmental Panel on Climate Change, a group of UN scientists, said that shifting towards plant-based diets would be a critical way to mitigate and adapt to climate change, as simply cutting carbon emissions from automobiles and factories won't be enough to avert an impending crisis.
Mintel found that 16% of U.S. consumers avoid animal products for environmental reasons. That reasoning is much more common with the 18 to 34 year olds, with nearly a quarter of that demographic saying that rationale applied to them. There has been a historical dietary shift away from beef in the U.S. American consumers eat about a third less beef than they did in the 1970s, according to the World Resources Institute.
Impossible's website includes a 2019 lifecycle assessment report by the sustainability firm Quantis, which spells out the smaller environmental footprint of the Impossible Burger. It found that the Impossible Burger used 96% less land, 87% less water and 89% less greenhouse gas emissions. "If Beyond's products help people switch from normal beef to a replacement, it's not so bad. But it should not be the end goal," Springmann said. "The carbon footprint of these processed plant-based products falls in between chicken and beef."
The data about U.S. beef production came from a 2017 lifecycle assessment by the National Cattleman's Beef Association, a lobbying group for beef producers. Beyond and its vendors primarily contributed the data for the Beyond Burger.
