Permanent materials that won’t degrade quickly would be far more beneficial for the goal, as it truly captures and removes the carbon from the cycle that feeds warming. Fuels, not so much, as the only good part is it supposedly replaces fossil fuels from the ground (i.e. new carbon), so less of a true impact on carbon in the environment. But will it be at a competitive cost to even make a large difference?
