The point of my earlier comment was that the inability to account down to the last carbon atom isn't a valid reason not to start with more generalized high-level estimates and work just from those until/if a better way of doing it is either becomes available or becomes a necessity.
It's like arguing that we might as well not accept the existence of circles because we can't calculate to the final digit of pi…when really, for most things, we don't need that level of precision to still do a good job discussing roundness.
Pi can be rounded. It's infamously difficult to compute externalities in any meaningful sense. Even more difficult to implement a fair and actionable policy for it. You can google "accounting for externalities" and read a bunch f articles and academic papers on the subject, which has been debated for decades.
Beyond fines for dumping chemicals in rivers, and carbon taxes, etc, stronger EPA, etc, I don't really have any good ideas for codifying a real actual plan into law. Probably easier to raise corporate tax rates up a few points from 21% to whatever and use it to fund green energy and cleanup projects etc, rather than change accounting methods to try and capture the costs that way.
