The idea is that cows, and all the infrastructure around raising them, are a huge source of greenhouse gasses, while just cultivating cow meat eliminates everything not directly related to producing a hamburger. More recent studies [1] cast doubt on that and even suggest as you do that cell-cultured meat may be more environmentally damaging, not less.

- energy123 2y agoCan you condense the argument for us? Why can't the supply chain be decarbonised?
- arrobbiato 2y agoOne of the main factors: generating the growth media for the cells is by no means carbon-free, and some of the ingredients are very very carbon intensive to produce.
- energy123 2y agoDo you mean energy intensive or carbon intensive?
- arrobbiato 2y agoCarbon intensive. Most of them are agriculturally sourced, and fossil fuels/feedstocks are not likely to be widely replaced in agriculture for several decades, at least.
