Yes, there it worked because there is a good alternative, healthier and same price, readily available.
There are many products on which society depend where the alternatives will have a similar CO2 footprint. Taxing these products will only serve to increase the base price.
Edit: I suppose what I mean to say is that adding a co2 tax shouldn’t become an issue for the lower incomes by raising prices while more well off persons can circumvent it somehow, further increasing the gap between poor and rich.
