Livestock are a significant contributor to food-related emissions. Meat and animal products generally have a higher carbon footprint than plant-based foods, with products from ruminant animals such as cows, sheep and goats having a particularly high climate impact. This is mainly due to the methane these animals release from digestion, a greenhouse gas which is 25 times more powerful than carbon dioxide in terms of global warming.
Cattle also require large amounts of land for grazing or to grow their feed. This is driving deforestation in many areas, which releases more greenhouse gas emissions, as well as leading to biodiversity loss.
Poultry, pork, seafood and eggs generally have a smaller impact on climate change than beef and lamb. However, in many cases the carbon footprint of these foods is still significantly higher than that of plant-based food. Reducing your meat intake makes a huge difference to your carbon footprint, and can even improve your health.
Find out more about the environmental impacts of meat and plant-based foods from a recent study which is summarised on the Guardian website.
