Don't depend on political willpower. If it happens it will happen because traditional carbon-intensive energy sources will become unprofitable because of renewables getting cheaper. And when any of that nasty stuff happens, first-world countries will be a drop in the bucket in the world's energy consumption structure and whatever they do or not do, will no longer matter. Basically this is why climate change efforts don't work so much now: OK you can implement these unprofitable measures, it will only result in your industry reducing due to incompetitiveness and third world countries displacing it - using whole lot less efficient, dirty, carbon-intensive technologies - making things worse. So, just wait for renewables to actually become cheaper with no subsidies and drive carbon-based energy out of business. Which is likely to happen, especially as the main missing link - batteries - are making huge progress in cost in the recent couple years, finally. World energy landscape will look totally different if they get 3x cheaper than now, and that is more than likely. If it doesn't ever happens there is nothing we can do and we'll just have to learn to live with the climate damaged to whatever point it happens.
