Germany’s main environmental protection agency Umweltbundesamt UBA advocates a reduction in the number of animals by 50 percent. In view of animal emissions, UBA believes that a carbon tax for cows is a logical idea, but after heavy criticism it withdrew the proposal. Nevertheless, the UBA is calling for a significant reduction in the effects of animal husbandry on the environment and climate, because the production and consumption of animal food is currently not sustainable from an environmental and climate point of view, nor from a health and animal welfare perspective, according to the UBA.
