What if the whole problem is that of "growth"?
Here's one possible chain of thought. I don't fully subscribe to this, so please feel free to poke holes in it:
1. The biggest polluters tend to be commercial enterprises
2. They are aware of the environmental impact of their actions, but are reluctant to stop
3. They are staffed by (mostly) normal human beings, but they continue because they are heavily incentivized to show continued growth
4. Businesses can no longer reach a "steady state" -- they must continue growth or be considered failures
5. Growth appears to be demanded by stockholders
6. Stockholders need growth for return on their investments
7. Investments are necessary because of... inflation ?
Ergo, stop inflation, slow down growth?
