Taxing carbon is probably the most effective way of curbing greenhouse gases that cause climate change. But because taxing carbon emissions will raise gasoline and other energy costs for households and industry, it may be the most politically treacherous step any government can take. Undaunted, Europe should forge ahead with an ambitious plan to make the cost of using fossil fuels effectively exorbitant. The economic impact on Europe would be enormous. But Europe’s actions could also have a significant impact on the United States.
