If we believe that every country has the right to develop, than the poorest countries emission will increase. Better technology will flatten that increase but those are expensive. Wealthy countries pioneering the widespread use of these technologies will reduce cost and allow developing countries to deploy them in the future.
Like, instead of committing millions of your citizens to coal mining with picks and steam-powered lifts, you can just buy or produce turbines and solar panels, put them up and enjoy the benefits of electrification. Worst case, you build cheap has turbines and buy or pump LNG.
Being charitable, it’d clearly be an environmental disaster if everyone in the world consumed oil at the per capita level of OECD countries. I imagine global oil consumption would multiply manyfold.

I too used to think this, but it seems like most of the progress in solar has come from China. Similar with nuclear power plants.
