The major issue blocking their action is that every Republican votes against it, and a handful of Democrats are bought off, so they vote with the Republicans.

In 2008 we had cap-and-trade legislation, but it didn't get a vote in the Senate because supporters counting votes saw it couldn't get even 40 votes
in 2022 the Inflation Reduction act passed, getting 50 + 1 votes in the Senate, after being converted in to an almost-all-carrots-no-stick type bill to appease the few Democrats who were being paid off by the fossil fuels industry.
We're on the right trajectory here, just not nearly fast enough
