> The Department of Energy's Carbon Negative Earthshot seeks to slash the cost of carbon removal to $100 a tonne by the end of the decade At 40 gigatonnes a year, that would be $4 trillion, which is about 5% of Gross World Product.[0] It's probably still cheaper to avoid emitting the CO2 in the first place, but that does put an upper bound on the cost of reaching net zero. Of course, no one wants to take a voluntary…
More importantly, having an actual price tag on removing carbon from the atmosphere would allow carbon markets to finally work. Assuming there is enough political will to properly monitor and tax CO2 emissions worldwide, which is a huge ask. A lot of companies and countries will be tempted to lie because it will make their products more competitive.
I think it’s also interesting to trace how much all of it come from really good, simple and forward thinking principles, to slowly become the state we are in now.
For instance, following your idea, there will be the issue with countries that produce more CO2 than they can afford, but we can’t make them pay as it would literally be a matter life or death to them. So they get an exception.
They then become a beacon of CO2 relocation. We start to pass more laws to limit that trend, but the existing companies will be grandfathered. They then have a monopoly on the scheme, and also find other loopholes, progressively expanding the amount of CO2 they can get away with.
During that time, these countries will be more and more CO2 swamped, degrade beyond belief, and someone will be pesting against the demon that thought about taxing countries in the first place.
To put my naive ideas out as well, I kinda see economic tricks the same way we say “don’t try to solve social problems through technology”. We should straight get the bigger economies to shoulder infra construction in weaker economies no strings attached. No loan, no debt, no nothing. We’re all extinct anyway if we don’t do it.
