Jonathan Rauch, dla National Journal, propone una via "di mercato" alla riduzione della dipendenza petrolifera.
Here is the idea: Propose an international treaty whose signatories would agree to eliminate gasoline from their transportation systems by a date certain -- say, in 30 years. Seek initial support from Europe and Japan, but open the treaty to any country that cares to join. Specify only that the treaty should allow signatories to reach the goal in any fashion they please and that it should allow for tradable credits against whatever interim targets it sets. That way, countries can act at different speeds and in different styles. Then let the negotiations begin.
Sicuramente si tratta di un'alternativa preferibile ad una sovrattassa sul petrolio od a sussidi per gli amici "ecologici", con le conseguenze che ben conosciamo.
