how much co2 is released each year ? -> "The world emits about 43 billion tons of CO2 a year (2019)"
This article -> 50$ per ton of capture.
product = $2,15 trillion to capture the whole year emissions.
US GDP 2020 -> $20.93 trillion
Only a few plants and ~10% of GDP from a single country could solve it.
Does this mean that global warming is almost a non-issue, but merely just a game of chicken to see who will foot the bill ?

- Aachen 6y agoWell, as another person said, it only works with high concentrations. You'd have to have this country of choice go and install the devices on all exhausts everywhere. There's still a percentage getting past the exhaust, there will still be emissions from fertilizer and the like, methane/nox/refrigerants are still a thing, and so we'd reduce the amount of emissions by, say, 75%. That would be amazing and hugely helpful, but not the solution. In the end we'll need something around 100% (bit more due to overshooting, more likely than not).
- GistNoesis 6y agoOk, I hadn't understood, that this new solution was only applicable only to the CO2 produced by combustion for which we can easily install an exhaust filter. You quote this fraction at 75% : With some efforts we can get 75% reduction at 50$ per ton. What is the cost per ton to remove the CO2 from the atmosphere for the remaining 25%, and for the CO2 we already have emitted in the past ?
- hannofcart 6y ago> ~10% of GDP from a single country The 'single' nation you mentioned has many times the GDP of others. 2.15 trillion is most (over 70%) of the fifth largest economy.
