Pollution is an entirely different topic but probably a much better target for societies efforts than CO2 emissions.
Look at cars these days with 3 year leases and think about the pollution created by getting another new vehicle every 3 years whether you drive 5,000 or 25,000 km per year. Look at all the crap crammed into a car these days that causes pollution to manufacture. Can you even get a mid range vehicle without A/C? Can you take a $3000 price reduction by selecting your preferred trim package less air conditioning so you can save the environment? Look at the miles of wiring to build a car now. And then the owner punts it down the road in 3 years.
And how about the guys with a second home. You are going to charge him for co2 emissions on energy used but what about the pollution created in the life cycle of building, maintaining and demolishing/disposing of the house or the real estate bulldozed to build it and infrastructure to bring power, gas, water and take away sewage. There is a lot of pollution and environmental impact in this lifecycle but the government thinks charging for co2 on electricity used is the best way to protect the environment.
So yes, pollution is a big deal but government says taxing to slay the co2 dragon is what is important. Consume and throw away what ever you want as long as you pay your carbon tax on fuel.
