How could time be a factor here? How many output values should be there?

I was maybe thinking the typical ESG goals to make this more aligned: current price, 2030, 2040, 2100? whats your opinion on this?

hoernschen commented 4 months ago

Yes that is a very good idea. Maybe also 2050?

This Paper perfectly addresses this, even though there are many variables and options, this is very recent paper (2024): https://www.pnas.org/doi/abs/10.1073/pnas.2312030121

Table 2. Social cost of carbon, alternative scenarios (2019$/tCO2) Scenario 2020 2025 2050
C/B optimal 50 59 125
T < 2 °C 75 89 213
T < 1.5 °C 3,557 4,185 16,552
Alt damage 124 146 281
Paris extended 61 72 159
Base 66 78 175
R = 5% 32 37 74
R = 4% 49 58 107
R = 3% 87 102 172
R = 2% 176 207 302
R = 1% 485 571 695

I would propose the T < 1,5*C number, due to it's direct link to the paris agreement, of which a majority of western country apparently committed to, but fail to achieve.
