Climate change mitigation doesn't work if the fossil fuels just make it cheaper for other countries to use them. Russia and the Middle East aren't walking away from trillions of dollars in oil reserves and the BRICS aren't going to stop developing to keep the world from getting a couple degrees hotter in a hundred years.
If they really wanted to do something about climate change they'd be pushing next gen nuclear energy to the forefront, make clean electricity super cheap, and drive electrification by outcompeting fossils.
The energy policy we have now in the West was designed by scammers and morons.
