You don't need to measure the carbon cost of everything. You tax carbon at the source, like power generation and oil drilling. The costs will naturally balance upwards.
The downtown parking lot, for example, probably doesn't have recurring carbon costs. The gasoline people use to drive there will be more expensive from the carbon tax on oil and gasoline production, and the cement or asphalt that takes electricity to produce will be covered by the source-charge on power plants.

If you're importing from somewhere that also has a comparable carbon tax it's fine, but otherwise you have to apply the carbon tax to all imports. Doing so also likely violates any free trade agreements you've signed. It's a hard problem, but the gains are massive, so it's worth it. It'll be a lot easier if a set of countries do this together.

- darawk 6y agoI think the solution here is likely to pass extra-onerous taxes on imports, and then tell the host countries "If you don't like it, apply the tax yourselves, and then we'll remove ours once we deem yours satisfactory".
- coddle-hark 6y agoI dunno, that sounds like a trade war to me. If it were this easy there’d be no need for international diplomacy.
