What goalposts though? I can safely say "I'm doing my part". But overall it's nothing, not even a blip. There's more spoiled meat and broken phones in the local dump than I'd ever use.

This only works if everyone does it, production will fall of there's no demand. Although that would bring economic problems in the current system...

Taxation may work, but the best way is to change the culture. The alcohol and tobacco tax has skyrocketed, yet people still drink and smoke a lot. I think the mindset of "not smoking is better, I'd rather never start" worked better than the taxes.
