I totally agree with you, the gain is independent of C.
In your original post, you give a scenario where the cell-based meat enters the market in 100 years, while you seem to believe that an actual estimate would rather be ten years or less. I wondered if this was because you overestimated C, or underestimated F (both affect the timeline, but only F affects the gain)
I now understand that you overestimated C, so this doesn’t affect your prediction about the gain
Thanks for clarifying!
In your model, cell-based meat replaces animal-based meat in 100 years, thus each euro invested now will mean a reduction of 10 ton of CO2e in 100 years. I’d argue that one ton of CO2 now is worth way more than one ton of CO2 in 100 years.
How much more? One way to compare the two would be to imagine what would happen if, instead of spending your one euro now, you were to save it, and spend it in 100 years. With an annual interest rate of 5%, you would get 130 euros in 100 years, which you could then spend on the best carbon offsetting mechanism at the time.
My point is, in term of CO2 averted, it’s probably more effective to save money and spend it in the future than to fund cell-based meat R&D
PS : To be fair, it’s way better if many are willing to fund cell-based meat R&D too. If the funding goes from 10^8 up to 10^9, we only have to wait for ten years for the cell-based meat, and therefore the saving strategy isn’t as good anymore.
