Green Alliance's work on food has explored how different organisations are addressing the impacts of animal protein production and consumption. The UK's consumption of meat and dairy products is estimated to be responsible for eight per cent of our consumption related greenhouse gases. The majority of these emissions derive from methane and nitrous oxide emissions, which are by-products of rearing animals. The significant contribution that animal protein makes to our overall environmental impact is clear and unavoidable and will be integral to discussions about how to lower the impact of our diets.
