My solution would simply be to massively focus on nuclear. Replace all existing coal plants with nuclear plants and plug them into the network.
Once you have mass production of nuclear power plants, you can start using nuclear power to create liquid alcohol fuels. Start a process of changing cars to electric or alcohol based fuels, the same goes for ships and eventually planes.
The process of switching to alcohol based fuels can be started in parallel, with early on using fossil fuels.
Start taxing fossil fuel usage to make people move over to liquid fuels.
This vision was created out by one of the nuclear innovates. He invented the PWR (currently used nuclear) but rejected it as a terrible design for human energy production. His insistence that PWR were not 'perfectly save' got him essentially fired. He had come up with Molten Salt reactors to fix all the issues of PWRs.
His vision was more to use nuclear heat to turn salt water into water you can use for irrigation. Not really produce Liquid fuels in a carbon neutral way but the vision makes sense.
Now, unfortunately this should really have started in the 70s, but it would have been the most systematic approach to actually solving the problem. But of course that requires the population not to freak out about nuclear and to accept potentially higher oil prices.
