The current - and still ongoing - UK coal-free run, has been on the back of gas (30%), wind(25%) and nuclear(20%). Overall figures as obviously wind and solar can vary widely on individual days. Biomass and solar, and a little bit of hydro make up the rest.

Certainly UK is dropping coal quickly, and I'm not dismissing that. Yet government has made onshore wind, and domestic solar far more difficult. They're promoting biomass - via imported mature cut wood, and encouraging gas. Drax is still our biggest emitter and an environmental mess. Farming is continuing to ignore decades-long warnings of soil decline, forests globally are still being clear cut and burned for cattle or palm oil. Recycling has become "export the problem and forget about it".
Wind, solar and electric vehicles have become viable, yet despite that, overall emissions are still increasing. So beginning to scratch the surface is about right. Real government actions are still avoided.
It ain't going to happen easily when the rich-and-powerful's self interests are served by maintaining a foil, a semblance, of environmental concern.
Great, you're recycling the plastic food trays your meat is shipped half-way around the World in. Now, ditch the car and use public transport; change your company marketing processes to prefer economy to profit ... oh that's right, you're too important to have to do those sorts of things.
Actually, best hope might be concentrating all jobs in very urban areas and making it costly to get into relationships/have children so women themselves opt out of it and drop the birth rate as they wouldn’t be able to afford the amenities they want.
Source? The world’s population is urbanising. That trend shows no sign of slowing.
Also, is that going to be common across all cultures?
