I was going to say this will never work, but actually I think it might with a couple of additions. You'd need this signed into international law. Mass protests could probably help with that, but you'd also need an international election drive towards green parties among the youth to get a critical mass of supporters at the UN level. You'd also need to handle enforcement and compliance, which is where these agreements have fallen down in the past. Some nations, and a lot of people, just don't care about climate change, so you'd need hard consequences for polluters. You'd also be parting oil-rich states and agricultural beef businesses from the source of their income. The farmers won't do much but the oil states would probably go to war over it. On that topic I'll say this: electric cars. Yes they still need energy, no that doesn't make it "the same as driving a gasoline car" as the EV energy doesn't have to come from fossil fuels (and increasingly is not), which means you can move at a macro level away from oil and coal over time. If you remove the demand for fossil fuels you don't need to ban them. I'm still not convinced it's impossible if we take the problem seriously and stop pretending it doesn't need a global response.
