Interesting proposal. Thank you for your work on this! Carbon emissions seem to be a classic tragedy of the commons and I believe the only effective way to prevent a tragedy of the commons is through better governance. Creating these kinds of promising new policies is one half of the solution, activism to generate the political will to enact them is the other half. (Disclaimer: I work on the activism side. We haven't given up and neither should any of you)
