Except for the fact that if you design pollution taxes correctly, you can address those competitiveness concerns through revenue recycling, revenue neutrality. Again, I can go back to the example of Sweden. Sweden took a leadership position in the European Union and put quite a significant tax on emissions of nitrogen oxides. The result of that was a dramatic decline in nitrogen oxide emissions and the development of some new technologies that Sweden was then able to export.
The beautiful thing about pollution taxes is that they create an incentive for continuous improvement, which is exactly what we want. We're developing clean technologies that we can then not only use here, but export to other countries.
