French carbon tax

It is my personal believe that a carbon tax is one of the few real policy measures that might curve the ever increasing carbon dioxide emissions. It is promising to see that more and more countries are looking at ways to implement a carbon tax. Of course this should be accompanied by an equal reduction in other taxes (e.g. VAT, why do we tax added value anyway ?). Just now Reuters published some news on the French plans for a carbon tax in which they also mention the Swedish initiative for an EU carbon tax.
