Polices such as carbon tax are being strongly considered. Biden is still optimistic a deal can be reached. I feel optimistic even if a deal cannot reached, Biden and Schumer/Pelosi will make Manchin/Sinema face 24/7 accountability voting to kill the bill.
Biden has also mentioned he is ready to aggressive through executive/epa action just like the student loan forgiveness/debt erasure (referencing recent public loan forgiveness good news stories and $10,000 outright forgiving through EO).

Add in falling covid cases plus more and more vaccination, eventually his approval will very slowly inch back into positive territory. It is up to Biden show he is not someone who gives up and wants people to be reassured there are other ways. It is going to be a very slow increase no matter the exceptional good news stories he creates. He knows how to read approval ratings.
If Biden positively controls the next few weeks plus November, December, and January on aggressive student loan debt reform/relief, his approval ratings will be back to 50% by February.
