Climatarian is an easy diet that’s good for the climate and good for your health.
Simply avoiding beef and lamb in everyday meals saves a tonne of CO2e every year.
You don’t have to give up meat entirely and even if you eat Climatarian only half the time you’ll be making a real difference.
Eating Climatarian saves
the equivalent emissions from
taking six short haul flights
driving 3,500 miles
Food causes at least 24% of all global greenhouse gas emissions.
Meat causes far higher emissions than plant based food and beef and lamb have a much greater climate impact than pork and poultry.
More than half the world’s crops are used to feed animals.
Livestock alone causes 18% of global emissions – more than all transport!
Not all meats are the same.
Beef and lamb have
a far higher climate impact
than pork and poultry
Ruminants – sheep, cows, goats and deer
Grazing animals that chew the cud are called ruminants.
They have a much higher climate impact than other meats and animal products.
Food ferments in their four stomach digestive system, so they burp methane gas.
They use more land, need more energy intensive feed and produce more manure than pigs or chickens.
Crops grown for animal feed produce more nitrous oxide than crops for people. Nitrous oxide is released by fertilisers and manure and is hundreds of times more potent than CO2.
Wild deer is an exception and is considered carbon neutral so long as there has been no human intervention in its production.
Climatarians avoid beef, lamb and other ruminant meat – goat and deer.
While we all need to eat less meat for our health and the climate,
Climatarians don’t have to give up meat entirely
and can still enjoy pork, poultry and fish for an easy mixed diet.
Compared with other meat sources, beef production
causes 5 times more CO2e
uses 28 times more land
uses 11 times more water
Compared to staple plant foods such as potatoes, wheat and rice, beef uses/causes
causes 11 times more CO2e
uses 160 times more land
uses 8 times more water.

Spot the difference.
Beef and mutton stand out high above all other foods,
emitting 60 to 70kg greenhouse gas per kg consumed.
