Greenhouse gases come from a handful of different sources like cars, production, and power. But one often forgotten greenhouse producer comes from agriculture – and more specifically, animals like cows and pigs.
Livestock production accounts for about 18% of all global greenhouse gas emissions, primarily with methane and nitrous oxide. But in the US, there’s been a gradual shift away from these.
Diets in the United States has seen a steady change over the last 15 years, something that’s led to a decrease in greenhouse gases. The primary cause of diet-related greenhouse gases was cattle, and the US diet has been gradually shifting away from beef.
Data from a national dietary survey of US adults has suggested that over a 15-year period from 2003 to 2018, US adults consume about 40% less beef than they did previously. There was also a slow move away from other animal products like milk, eggs, and other meats, while adults maintained a relatively consistent caloric intake suggesting a move to plant-based replacements.
Companies like Impossible Foods represent a growing trend in diets to move away from meats, with fast-food chains like Burger King and KFC even offering plant-based alternatives.
“From a nutritional standpoint, our products match the protein quality and content of the animal products that they replace,” Impossible Foods founder and CEO Patrick Brown told CNBC in a 2020 interview. “Ours is a clear winner from a health and nutrition standpoint.”
The survey itself highlights that US meat consumption is not sustainable for a net-zero future.
“(Greenhouse Gas) trends in the US diet are both exceeding planetary boundaries and capable of substantial impact reduction through changes in dietary patterns,” the survey read.
