There are carbon border taxes that do no sound that bad

Sir in the greening of globalization, January 4, you correctly speak out against carbon border taxes since these could be sheltering a new dangerous breed of protectionism. But, given that Europe and the world has to pay so much more for oil and has to see its environment so much more contaminated, just because the US does not want to restrain its consumption of gasoline/petrol perhaps a carbon border tax on US products that considers this would not be such a bad idea after all.
