I would love to see this model made feasible with a carbon tax, so that companies that couldn't meet a carbon goal could just buy their way down artificially or pay the government the taxes.
And at the current prices it doesn’t cover even 20% of the cost of removal of co2, not to mention the environment destruction.
If everyone was simply free to pollute all they wanted, we'd all end up severely ill, which doesn't sound like freedom to me.
there should be no “but” in this sentence - the libertarian approach would be to allow anyone to pollute as much as they want as long as they clean up the pollution afterwards (or pay for cleanup :) )
