The trace gases for sure; the Kigali Amendment to the Montreal Protocol has been ratified by the key countries which manufactured them, and their use in new equipment ended about a year ago.
Fossil fuel use phase-out is getting started. It very roughly looks like this:
- Generate electricity without using fossil fuels
- Electrify everything we can
- Stop doing the things we can't
It's unclear if fossil fuel phase-out will happen at a pace fast enough to limit the warming to 2°C above what it was in the late 1800s.
Deforestation is proceeding at a slower pace in some parts of the world due to local political change. Not everywhere though, and there's a lot of work still.
Cutting the ruminant herd...not even started yet.
