Carbon tax works fine if politians are willing to stick to it. First set some goals and make sure that those goals need to be met. For example, 0 net CO2 emissions in 2050, 50% less than 1990 emissions in 2030. Then announce that each year, CO2 tax will be set to have effect. I.e., plot how to go from today to 2050, how much CO2 emission is allowed for each year and an estimate what to CO2 tax will be. The CO2 can just be a general tax, and income tax can be reduced to compensate. No need for the government to spend all of it on new technology. Of course, some programs to develop markets may help. When CO2 costs are more or less predictable, companies will quickly figure out ways to avoid CO2 emissions. There is one big if, if the government cannot find a way to grand permits for green energy, transmission of green energy, etc. then the standard of living may quickly go down.
