Make a healthy climate a legal right that extends to future generations

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.
Perhaps the climate requirement needs to get incorporated in WTO and World Bank rules. Then sanction those who don't meet them...
Shaping it as a trade agreement among a small set of nations that any can join should make it easier to get started, to get buy-in and to get those enforcement provisions that it desperately needs. https://issues.org/climate-clubs-to-overcome-free-riding/
The real issue with climate change is that it is not electorally popular to do anything other than a few token gestures. The increased gas taxes contributed to the yellow vest protests in France. The Australian election upset was also spurred by concern that one of the parties would try to cut fossil fuels.
I do not know that trying to do an end around the electorate and appealing to the judiciary on a novel legal theory is going to work in the long term.
We need to tackle the hardest problem, which is changing hearts and minds. I don't have a suggestion here, just pointing out that we need to be honest about the real problem.
It's like complaining about Brexit and/or Trump. Your problem isn't the situation itself, it's that half the population looked at an option utterly abhorrent to you and said "sounds good to me".
If there is a move from shareholder primacy to stakeholder primacy, the environment can be one of the stakeholders and there could be laws preventing businesses abusing this stakeholder.
And there is no such thing as a healthy climate -- an unhealthy environment is caused by local pollution, not greenhouse gases.
We can legislatively protect the Earth for the future --and it should be welcomed-- but the future is coming for us. Over extremely long horizons, no law will save us. And modern humans have only existed for 200,000 years -- would such a law protect generations that are no longer Homo Sapiens, but are our descendants? If we do indeed succeed in protecting our planet, with enough time (short by geological standards) we won't even exist in our current form.
It seems counterintuitive to be worried about climate change, to protect future generations, but then ignore planetary death because that's "too far out", when the whole premise of stopping climate change is to give future humans a shot at continuing the species.
