Could a tax on meat help us save the planet?
That’s the interesting question posed by Simon Fairlie in a Guardian article a few days ago.
It is, I think, now becoming widely accepted that fattening livestock for human consumption is a very inefficient use of feed and water – and thus environmentally unsound. One way to reduce consumption of meat would be to tax it, perhaps treating it as a luxury item.
As usual here’s the tl;dr summary of quotes from the article.

Feeding cereals and beans to animals is an inefficient and extravagant way to produce human food … there is a limited amount of grazing land … the world will be hard-pressed to supply a predicted population of 9 billion people with a diet as rich in meat as the industrialised world currently enjoys, and … it’s not a very healthy diet anyway. [Additionally] … livestock [generate] 14.5% of all manmade greenhouse gas emissions.
… … …
Meat taxes have been proposed … the ideal solution might be not to tax meat itself, but to tax fossil fuels … meat production would decline as a consequence – partly because nitrogen fertilisers … for growing animal feed would become more expensive, and partly because there would be increased competition for grazing land.
… … …
Most proposals [for meat taxes] foresee different rates of tax applied to different animals … a pig fed on food waste and crop residues has a tiny fraction of the environmental impact of a pig fed on soya and grains.

If we were to have a meat tax, it would … be simpler to have a flat rate for all meat; and in the UK and the rest of the EU there is an oven-ready way of doing that … VAT … It is hard to think of a more seamless way of introducing consumers to the concept that meat … is a luxury item they will have to pay more for.
… … …
[Another] aspect of applying VAT to meat [is that] small livestock farms with an annual turnover of less than the £85,000 threshold could be exempt. They would benefit from an advantage of up to 20% over supermarkets for any meat they sell direct to consumers … [this] might help reverse the drastic decline in the number of small family farms, and give a boost to new entrants into farming. It would also provide a fillip to local economies, with farmers’ markets, community-supported agriculture schemes, urban food co-ops, small farms in the green belt, conservation graziers … likely to benefit.

It’s an intriguing idea, but one which I don’t see happening. The consumer in the developed world is far too wedded to meat as a staple food to accept what will be seen as an arbitrary price hike for no gain. But then again why not scrap income tax and charge VAT (or equivalent) on everything?
