The biggest issue that keeps accelerating climate change is that people buy too much stuff, travel too much, and more importantly eat in a way that is bound to destroy the climate.
Now go tell people to buy less crap, use more public transport and stop filling their mouths with beef and fish every day, good luck.
And even that would merely slow the progress, not stop or revert climate change.
Sincerely this is a disaster, each generation just keeps doing worse than others, gen z may actually be the firsts to really give 2 damns, or pretend better.
