I wish there was a better answer, like "we just need X technological breakthough" but the reality is we have had the tech all along. Nuclear has been here for decades but we just sat on it, didn't bother improving it, allowed crappy politics to keep it down so that other nations couldn't gain nuclear capabilities.
Electric rail could have easily taking 95% of trucks off the road if large nations properly invested in it, could also take a large number of planes out of the sky if you had high speed passenger rail to go with it.
We didn't need to continue destroying the Earth. We had the tech, we knew what to do, as a collective we shrugged our shoulders and said "who gives a fuck, I'll be dead anyway'.
