I've been thinking about this since yesterday when I first saw it. CDR is going to be asked to do a lot of work: compensate for long lived legacy buildings, transport and industry emissions post 2050; to achieve the 5-20 GtC/yr net negatives we need to stabilize at 1.5-2C; AND.. https://twitter.com/JaneAFlegal/status/1359027179863040005

to start drawing down our "CO2 debt", so we can return to 1C and maybe lower https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020AV000284. That's a lot of investment. Even if the rich countries accept their responsibility, we need to start thinking about institutional structures to make it happen.

What do CDR funding institutions look like? Something like an EU ETS where the caps go negative? A "drawdown bank account", funded by everyone above $10k per capital GDP? How do we allocate the drawdown across rich countries and time? I am so full of questions.

And how do we deal with the fact most truly negative CDR will be direct air capture + CCS, which means it will be done where there is cheap clean electricity and adequate geology. Is the world going to tolerate paying the Middle East, North Americans and Russia to do drawdown?
