I think we need to address the problem by preventing companies from externalizing their costs. If they had to pay exactly as much as it cost to clean up the pollution they emit then they will actually internalize that cost and have financial incentives to decrease pollution. I am obviously oversimplifyng since the cost is not constant and this would create a financial incentive to create companies that remove/ filter pollutants more effectively and efficiently.

It’s complicated because it requires international agreements but it’s a more realistic approach than thinking companies should do it because we need them to.
