Interestingly, although hash rate is climbing (mainly due to vast improvements in ASIC efficiency) Bitcoin's emissions are starting to plateau due to improvements in Grid carbon intensity & fully expected to drop following subsequent halving events.

The dotted blue line is MT CO₂ minus mitigation such as mining with Methane + Home/ Business heating. Other mitigating factors not included are mining curtailment/ demand response schemes & banking sector curtailment.

The large drop in emissions during 2021 is due to the China mining ban followed by the subsequent move of much of the hash rate to the US where grid carbon intensity is generally lower.

Bitcoin is arguably the best hope for the environment, not just because of its function as a buyer of last resort supporting renewable buildout, miners' propensity to use wasted and stranded methane, and its potential to replace fiat (which has had such severe consequences for the environment on so many levels the overall harm done is probably incalculable).

Even leaving those aside, the fact that it allows us to visualise radically new ways of designing society from the ground up. For example, bitcoin enabling Ocean Thermal Energy Conversion to be profitable in international waters, where startup cities (with novel legal and political structures) can conceivably be built around. This would afford completely unexplored opportunities around environmental sustainability.
