Canada

Like all of the comments about much smaller emobility support.

A $300/ton carbon tax ($3/gallon gasoline), is the right amount. Cost of air capture of CO2 claims objectives below this. But there are far better options to reduce emissions instead, such as wind and solar. It is also enough to provide a $4000/year rebate to every Canadian just from average vehicle oil use.

The argument for dropping these incentives is that it has run out of budget. Carbon tax and dividend is a zero budget program. It is almost as much as the EV incentive, but you can support local transit/trains more, micromobility, and moving closer to work/travel destinations. Home energy is also a tax/dividend source, and dividend becomes large enough to invest in saving "taxes".

With a $4-5k carbon dividend, you can also replace budgets for welfare/homeless programs to boost dividend/UBI by another $3k and solve homelessness, and work disincentives for those on welfare. Much higher "total" UBI becomes much more affordable, and empowering to people to make incentivized climate decisions, live without crime and divisiveness promoting hate.
