This is super important and also really hard to do right. The best way to tackle embodied carbon is through a 100% fee and dividend scheme, because then you can easily avoid the accounting games that companies will try to play: https://citizensclimatelobby.org/basics-carbon-fee-dividend/ https://citizensclimatelobby.org/basics-carbon-fee-dividend/ Passing such a law is difficult at a state level (though maybe possible). Where this also gets tricky is that sometimes attempts by companies to lower carbon, both operational and embodied, ignores rebound effects / Jevons paradox and so they can simultaneously say they're doing good while their total emissions are rising. This too is where a fee-and-dividend scheme will help.
