I propose Amazon and consumers pay for the environmental damage shipping these products using fossil fuels causes.
The EPA + Taxes (of various kinds) are how companies/individuals pay for environmental damage, and it's also how companies/individuals pay to protect the environment.
Cleanups use tax money, research into potential regulations to minimize impact uses tax money, etc.
So it's not some kind of outlandish idea, but at the moment the EPA is REALLY buddy/buddy with large companies so they're currently effectively neutered.
If you do, make sure to offset that with: (1) the reduction in retail space use for products, (2) the reduced amount of cars on the road, etc. etc.
