If the government had any backbone at all they'd rally people around the idea of committing to it and getting it done. In World War II people lowered their "quality of life" to support the cause. It can be done.
Incentives are another way. I still think a global carbon tax agreement would be a good idea: companies work together to implement carbon taxes and cut income taxes or a local equivalent. That helps eliminat the problem of production offshoring to cheaper carbon areas, and gived incentives to alternatives.
Actually making carbon economically unviable with our psychology works, obviously. I really, really hope we can figure out something else cheaper.
Finally, if we had a carbon sequestering method with no major side effects and clear costs, it would be psychologically easier to charge fossil burning industries and activities the cost of the CO2 emitted. Eg a fee of $30 per ton if that's the cost of sequestering. Of course, you'd need a way to measure the carbon impact of the sequestering, to make sure that process wasn't indirectly emitting carbon.
Reducing would also be highly useful, and I hope we will, but enpirically we don't seem to be built for it without some mechanism like what I described above. It's terrifying and dispiriting and I hope we figure out a way to work around our broken mass psychology.
Good luck.
In the meantime I sure would like to try some mitigation techniques.
We get what we vote for, for need to vote for backbones.
