This year we’ll be sharing a few notes from my colleagues on their areas of expertise. The first is from Martin. I’ll be back next month. - Lewis
In 2024, Denmark announced plans to introduce the world’s first carbon tax on cow, sheep, and pig farming. Climate advocates celebrated, but animal advocates should be much more cautious. When Denmark’s Aarhus municipality tested a similar tax in 2022, beef purchases dropped by 40% while demand for chicken and pork increased.
Beef is the most emissions-intensive meat, so carbon taxes hit it hardest — and Denmark’s policies don’t even cover chicken or fish. When the price of beef rises, consumers mostly shift to other meats like chicken. And replacing beef with chicken means more animals suffer in worse conditions — about 190 chickens are needed to match the meat from one cow, and chickens are raised in much worse conditions.
It may be possible to design carbon taxes which avoid this outcome; a recent paper argues that a broad carbon tax would reduce all meat production (although it omits impacts on egg or dairy production). But with cows ten times more emissions-intensive than chicken per kilogram of meat, other governments may follow Denmark’s lead — focusing taxes on the highest emitters while ignoring the welfare implications.
Beef is easily the most emissions-intensive meat, but also requires the fewest animals for a given amount. The graph shows climate emissions per tonne of meat on the right-hand side, and the number of animals needed to produce a kilogram of meat on the left. The fish “lives lost” number varies significantly by
It's interesting to think of this as a humanitarian arms race in reverse, competition to contribute to international aid has just experienced a massive "disarmament" in the US, allowing the UK "disarm" too. It could also be that Starmer is hoping to placate or disrupt reactionary movements as they inevitably rise in the UK. Ian Bremmer points out that the Europe lags behind the US in terms of these movements.
But it's all very depressing.
Is it really the case that the UK and US were competing for the gains to reputation that foreign aid brings? I suppose I’d try to answer that question by looking at the history of where the 0.7% target, which I thought was fairly broadly shared among rich countries, originally came from. One history I found said:
> It results from the 1970 United Nations General Assembly Resolution 2626. The 0.7% figure was calculated as a means to boost growth for developing countries. Since 1970, however, only several Nordic countries have met or surpassed this target.... (read more)
