It was Prime Minister Raffarin who made a public statement at the time of the Nairobi conference, saying that one of the things the French government was looking at was imposing a tax on annex 1 countries who either didn't take on Kyoto commitments, which would be Australia and the U.S., or countries like Canada who have Kyoto commitments but have turned their backs on it. It was the first time I heard about it. Some colleagues in France had been hearing about it for a little while. Where this will go in terms of the European Union and member states we don't know yet, to be quite honest with you.
