In November, TreeHugger covered France's proposed plan to impose a carbon tax on non-Kyoto countries. Last week, President Jacques Chirac demanded that the United States sign both the Kyoto Protocol and a future agreement that will take effect once Kyoto expires in 2012. His demand was paired with a renewed threat that Europe would impose a carbon tax on imports from nations that have not signed the international accord. Although the legality of the proposed tax remains in question, it could create significant pressure for the United States, as the European Union is the largest export market for American goods. Mr. Chirac said: "a carbon tax is inevitable, if it is European, and I believe it will be European, then it will all the same have a certain influence because it means that all the countries that do not accept the minimum obligations will be obliged to pay." Despite increasing international pressure, it remains unlikely that the current administration will ratify the Kyoto protocol.
