It depends - you might not change your today consumption. But when you replace your furnace, hot water heater, car, could you honestly say you wouldn’t preference efficiency just a little bit more?
Speaking personally, and I'm going to show my colours here... I bought a Chevy Volt in 2012 (drive EV now), take the bus to work in the winter, bike in the warmer months, use only a grocery bag of garbage for my whole house in a week, and use a refillery. So needless to say I probably take the situation more serious than most. We need people and industry to change what they're doing today. Waiting for people to get to the point where they change their furnace, hot water heater, and car is playing the long game.
Like you say that stuff will happen over time, so it's a waste to incentivize it. I'm also against incentivizing EV purchases, the economics have been clear to me since 2012, it simply costs less over the life of the vehicle to operate a EV.
The carbon tax payouts to the majority of people have done nothing but give people money to spend. The people who need the payouts get them long after the money is gone, unless you're very budget conscious no one in that situation is squirrelling the money away to cover the extra they pay because of the carbon tax.
I fully understand that very few people are like me, people here buy trucks for the one weekend a year they need one or choose to buy a big SUV over a more efficient van (truck sales have never been higher). If you priced things based on their environmental impact (which is well known) and forced recreational inefficient vehicle users to buy credits, then I think people would start to grasp the situation (if you need a truck for work (welder, farmer, etc.), you would be exempt through a rebate). And I fully endorse that EVs are not great for the environment either, so charge people for their environmental impact too. And when you take that money, don't give it back to people, spend it on transit, and renewable energy projects.
For industry, the government could sell them credits they need to buy (or be fined) if their environmental impact is over a certain amount (Cap) and then use the sale from those credits to build transit. If you're a renewables company you get credits for the renewable energy you create and can then sell that to a non-renewable or any other company to pay for projects and generation. To clarify I'm not just talking about oil and gas companies needing to buy credits, but all that have an impact over the cap. Either companies would continue to pollute and have to keep buying credits (especially as the cap drops) creating an incentive to create more renewable credits to sell them or companies innovate enough that we become carbon neutral. The goal isn't to abolish oil and gas, it's to get to carbon neutral. If we want to go for carbon negative, cross that bridge when we get to it.
