Global deployment of solar and wind power, plus a surge in EV sales, means emissions from fossil-fuel-derived energy will finally hit the downward slope.
It will make many uncomfortable to say it, but the hero in this story is China. If we didn't have their industrial might making solar cheap, then this wouldn't be happening.
China did the same thing the US did in the 50s. They went all-in on industrialization and building their economy, pollution be damned. And like the US, once they got on their feet, they dialed the pollution way down.
