Al Gore has a new ally in his fight for new taxes and regulations to limit carbon emissions. The New York Times reports that, for all intents and purposes, Jacques Chirac is blackmailing the United States:

President Jacques Chirac has demanded that the United States sign both the Kyoto climate protocol and a future agreement that will take effect when the Kyoto accord runs out in 2012.

He warned that if the United States did not sign the agreements, a carbon tax across Europe on imports from nations that have not signed the Kyoto treaty could be imposed to try to force compliance.

Trade lawyers have been divided over the legality of a carbon tax, with some saying it would run counter to international trade rules. But Mr. Chirac said other European countries would back it. “I believe we will have all of the European Union,” he said.
