Would a carbon tax on luxury items cut emissions?

A study published by One Earth found that taxing luxury items like private & long haul flights and carbon heavy vehicles could cut more GHG emissions than a blanket carbon levy on all goods. With a blanket carbon fee, all households are charged the same, disproportionately penalizing those on lower incomes. The study suggests that if 88 countries adopted luxury taxes, it would likely deliver 75% of the emissions reductions needed to keep global warming below 2°C by 2050.
