In Sweden we're around the equivalent of 7.2 USD / gal, due to high taxes. However, and I expect this to be the case in most European high-taxed countries, the taxes are just fed in to the general tax revenue of the government. Not ear marked for e.g capture programs. These taxes do of course fund some inovation projects etc, but I think it would be a hard sell politically even here to direct all carbon-related taxes directly into buying Co2 capture. For example, as renewables have grown larger in Sweden, the government has started taxing the production of solar power on larger installations (≈ roof of a warehouse), even if the energy is never sold/transmitted to the grid.
