Gasoline prices have little impact on demand.
https://www.eia.gov/todayinenergy/detail.php?id=19191For this reason alone Carbon taxes do not work. In my jurisdiction, we already have over 100% tax on gasoline. Partly for road building purposes, but still obviously not impacting usage.
Hybrids coming around ~2000 certainly had a visible effect but it wasn't enough. Which is why Rivian, a company which has delivered no cars, is worth 97 billion. Tesla is worth a trillion. Whereas Ford is only worth $78 billion. We must get to EV transportation asap. We must electrify our railroads. We must electrify our planes.
In fact, carbon taxes are bad. Very bad right now. Because prices are inelastic it makes the tax regressive and anti-compounding.
So gasoline prices go up. Trucking immediately is more expensive. Products prices go up. But because product prices are higher, inflation etc. trucking gets more expensive. Alberta recently had a carbon tax and allowed this circle to run for some time. An interesting thing happened. The prices didn't go higher. This is a problem. The price available to oil value crashed instead. So while WTI was about $50/barrel. WCS from Alberta went to $5/barrel. The albertan oil industry couldn't sell their oil. The trucks weren't running. Alberta repealed their carbon tax which nearly immediately fixed the problem. Their economy was basically halted. No trucks running means people will soon stop eating.
Imagine 10 years from now. We have maybe 30% of vehicles gone EV. Who owns those? The rich. The rich no longer pay the 100% tax for building roads. Who is paying for the road tax and carbon tax? the poor buggers driving the 15 year old shitmobile. The poor end up paying and the rich dont? Pretty regressive.
