Capitalism could solve this no problem if we just taxed externalities. Don’t even have to hit every level of the supply chain, just a big tax on fossil carbon removed from the ground, and maybe another tax where it gets transformed into plastic (a sort of externality-added tax).

The market then decided what’s still worth making and what’s not, based on the total cost including the new taxes, weighed against how much people are willing to pay for the stuff.

I’m curious how much the environmental costs of shipping products in aluminum containers v. lighter plastic containers changes the equation.

I also tend to think that an even better solution would be to have the consumer be the one with the container, and shipping the product in bulk, to be dispensed as a bulk item at a retail location. E.g., the packaging for shipping is the tank that the truck is towing, rather than a trailer full of individual use bottles.

It’s also worth noting that transport does not have a zero cost on the environment. It’s why we did away with glass, it’s so heavy it actually becomes carbon intensive to transport. Especially when you account for greater spoilage percentages (due to the glass being mishandled and breaking more often than alternatives). The equation isn’t as simple as it would seem. The true solution is less likely single use drink containers of any kind and more likely some sort of reusable bottle you carry around with you and could fill up.
