Swedish study finds a Climatarian diet essential to meet EU emissions targets.

A new scientific study shows that EU climate targets can only be met if we adopt a Climatarian diet and make some agricultural production technology changes.

The EU target is to cut greenhouse gas emissions by 80% by 2050 and requires a 65-80% reduction in food emissions alone.

The study from Swedish Chalmers University of Technology, Department of Energy and Environment, finds that halving ruminant meat – beef and lamb - consumption whilst continuing to eat pork and poultry, are essential to meet the EU target. This is the simple diet switch advocated by Climates in its Climatarian diet.

The study suggests the target can be met through a combination of technological changes, a small contribution from food waste reduction and the essential component, a ruminant meat free diet.

In particular, deep cuts in beef and mutton consumption seem to be unavoidable if the climate targets are to be met,” the study claim. “However, dietary changes for meeting climate targets need not—as is often claimed—necessarily entail a reduction in total meat consumption.”

“The scientific case for the climatarian diet as a major player in the fight against climate change has been reinforced by this latest study from Sweden,” said Biba Hartigan, founder of Climates. “Action on climate change is urgent and we don’t have to wait for government or industry to implement technological changes. Diet is an area where we can take charge of our climate impact in our everyday lives and the simple shift it takes to go Climatarian can make a big difference.”

People can pledge to go Climatarian and track how much carbon they save day by day at

The climatarian diet was devised by Climates network, as an easy way for individuals to reduce their carbon footprint without giving up meat.  The average UK citizen eating 110g of meat a day could save a tonne of CO2e a year, equivalent to three return short-haul flights or driving 3,500 miles a year.

    Each block represents 10 kg CO2e per Kg meat, so 200 for beef, 30 for pork, 10 for poultry

    Maybe now our governments will put a bit more emphasis on ways to tackle climate change other than just cutting fossil fuels.
