Actually the tragedy of the commons cannot be stopped by one government. If USA chooses to tax all externalities perfectly, both our production capacity and consumption will be a tiny sliver of its current quantities. By GHG alone we'd lose 80% of our economy, but that doesn't take into account the potential cost of removing dioxin and PFAS from our groundwater, remediating lithium mines, cleaning our air of fly ash, preventing any toxic chemical leaks, making our rivers and lakes and ponds drinkable again, etc. I believe that would reduce us to about 1% of our current GDP.
Assuming we didn't riot ourselves to rubble, other nations will quickly outstrip us. Eventually we'd be a vassal state of another superpower. Either because they'd buy our politicians, use crises of supply shortages to force us into free trade deals which axe our externality taxes, or via outright force.
Other nations would do to us what the USA did to Latin America when those nations wanted to throttle their development for ecological reasons in the 60's and 70's.
Sustainably, we probably wouldn't even be able to keep and train a competitive military -- 6% of our nations carbon emissions are from our military, accounting for 52% of federal carbon footprint, and our military emits more GHG than 140 countries (individually/separately).

Perfect is the enemy of good.
The US could focus on lower cost - high impact externalities taxing.
It could persuade, cajole, bully its partners and allies to agree to a treaty doing the same. It did it for FATCA, for sure it can do it for climate change and general environmental destruction.
Once you have such an international treaty in place, most of the rest of the world would follow. US partners and allies are probably 70% of the world economy, and the countries with the most slack, economically, that can best afford this.
