It was amazing. Scientists said, this is bad and this is what's causing it. Governments went, well let's ban cfcs and hfcs. Manufacturers went, ok we'll just move to an alternative. And that was it.

No push back. No party politics. No anti-zoners. Nothing. It was just done.

The only other thing in my living memory that went as well as that was Y2k. But that was driven by corporate self-preservation

I like your optimism, but apparently DuPont did try to squash it with trademark violation threats for the use of the word Freon(tm) in an academic paper, as well as trying to convince a conference organizer to push it off the bill.

I just learned about this whole insane story yesterday from the cautionary tales podcast https://timharford.com/2022/11/cautionary-tales-the-inventor-who-almost-ended-the-world/ and there are sources there but I haven't read the book yet, though it sounds interesting enough to have a go at!

Edit: formatting, added the conference part that I just remembered.
