Livestock are a significant contributor to food-related emissions. Meat, cheese 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. Going vegan or vegetarian makes a huge difference to your climate impact and can even bring health benefits too!

Cutting animal products out of your diet really is much easier than you might think. Setting out to try it for a month will help you to stay motivated and explore your options.
The most popular time to do a month of vegan eating is January for Veganuary. This initiative has become increasingly popular over the last years with thousands of people participating.
