I’m surprised by the level of agreement between our assumptions. In your model, 200 M$ funding is required to advance clean meat with 0,7 years, whereas I assumed 100M$ and 1 year. You assume a lower greenhouse gas saving: 50% of the current 7,8 Gton CO2 emissions, whereas I assumed an increase in meat consumption in businass as usual scenario, and a reduction of 1 ton CO2 per vegan year, that means a reduction of around 10 Gton (assuming 10B people), but you assumed a 25% probability of success, whereas I assumed 10%. But with more lognormal error distributions, you arrive at higher $/ton estimates. Here’s my guesstimate
I too was surprised when I first read your post. I find it reassuring that our estimates are not far from each other, although the models are essentially different. I suppose we both neglect some aspects of the problem, although both models are somewhat conservative.
I agree that it is probably the case that cell-based meat is very cost-effective at greenhouse gas reduction, and I would love to more sophisticated models than ours.
