Difficulty cannot scale downwards to the level you describe because then it ceases to be Bitcoin. It's supposed to be extremely difficult, this is what secures digital scarcity.
It doesn't help to speak in simplistic absolutes. Miners can definitely become more green and rapidly so. The massive move from China to the US that took place over the last few months likely has dramatically changed the energy mix to mine Bitcoin, for the better. There's also a Bitcoin mining council to promote best practices in renewable mining. There can be additional incentive structures (CO2 tax) to further discourage dirty mining.

Bitcoin interprets carbon tax as damage and routes around it
No it's not.
These sorts of arguments fundamentally misunderstand the Sisyphean design of Bitcoin's proof-of-work algorithm: difficulty is scaled to absorb any changes in hash power, and expending hash power is rewarded with a chance of minting coins and/or collecting fees.
Bitcoin could be made sustainable and clean today, with no extra infrastructure, no optimised hardware, no new solar panel breakthrough, etc.: miners simply have to turn off their equipment, then difficulty will adjust downwards, and Bitcoin would become efficient enough to run off a solar-powered RaspberryPi.
That won't happen; and for exactly the same reason miners won't stop burning cheap fossil fuels as well as diverting as much renewable power as they can away from useful projects like electrified transport, desalination, aluminium smelting, HVAC, etc.
