I see the carbon tax as a 'stick' (to penalize undesired behaviour, in this case emitting carbon), but it needs to be coupled with a 'carrot' to encourage the desired behaviours.
I'd like to see a carbon tax coupled with massive investments to make public transit legitimately good. There are too many places where there is no viable alternative to driving, a carbon tax will unnecessarily punish those people without giving them a reasonable alternative.
The carrot is doing the things you want to do like getting from A to B or building a home.
Government ‘carrots’ are almost universally a terrible idea because they codify specific solutions. Instead you can get the same effect more efficiently with a carbon tax large enough for people to notice.
