Reducing supply without reducing it enough does more harm than good and reducing it enough without political backfiring is not possible. On the demand side, people mostly live viable alternatives like Tesla cars for example so that is where rhe focus should be. Cars aside, airlines are not going to convert their fleet to a yet non-existent electric commercial planes because of low supply, matter of fact, if all of US stopped extracting and refining oil, they will use it as an excuse to hike prices but in reality that will may not change prices because at the end of the day it costs what people are willing to pay for it, there will not be a global oil shortage, just a temporary logistics nightmare. On the other hand, cruise ships are by far the most notirious class of polluters. So perhaps targeted taxation of oil is what you need.

If I can compare it to something it would be trying to get a heroin addict (or even serious alcoholic) to stop using. If you succeed in cutting off all supply right away, they die. If you cut off supply locally, they will get it somewhere else where you can't help them get rehabilitated. Half measures are almost always worse than not doing anything.
