Human consumption of meat and dairy products is a major driver of climate change but has been largely overlooked in national and international climate change policy. Using data obtained from a twelve-country survey and from focus groups and stakeholder meetings in Brazil, China, the United States, and the United Kingdom, this report explores public understanding and awareness of the links between meat and dairy consumption and climate change. It makes recommendations as to how state and nonstate actors can develop policies that support sustainable diets at the national and international level. The report will help to inform discussion around demand-side measures to reduce the climate impact of the livestock sector, measures that are essential to meet international climate targets and realize important health, environmental and societal benefits.
