Wealthier nations must slash their meat consumption by at least 75 percent in order to meet climate goals, researchers at the University of Bonn advise.
To meet global climate goals, wealthier nations must reduce their meat consumption by at least 75 percent, researchers at the University of Bonn in Germany found in a new study. Slated to be published in October in the 14th volume of the Annual Review of Resource Economics, the study—titled “Meat Consumption and Sustainability”—examines the environmental costs of consuming animal products at current rates.
Researchers point out that half of the grain produced worldwide is fed to animals who are then turned into food—a costly inefficiency when it comes to resource usage. Animal agriculture is also a major contributor of methane, a powerful greenhouse gas that accelerates global warming.
Researchers explained that the average European Union citizen currently consumes 80 kilos (176 pounds) of meat annually—and the average United States citizen consumes a whopping 124 kilos (270 pounds) of meat annually. Maintaining these levels of meat consumption is not feasible for the growing world population, which is expected to reach more than 10 billion by 2050.
“If all humans consumed as much meat as Europeans or North Americans, we would certainly miss the international climate targets and many ecosystems would collapse,” study author Matin Qaim, a professor at the Center for Development Research (ZEF) at the University of Bonn, said in a statement. “We therefore need to significantly reduce our meat consumption, ideally to 20 kilograms or less annually.
The war in Ukraine and the resulting shortages in international markets for cereal grains also underline that less grain should be fed to animals in order to support food security.”
The researchers’ recommendations mirror those previously suggested by other groups, including Greenpeace which urged the EU to slash meat consumption and production by 71 percent by 2030 in order to mitigate the devastating impact of animal agriculture on the climate crisis.
