if airlines  from the  us  don't pay up for their carbon dioxide emissions, they have to face curbs in Europe.  On March 14, the  eu's  transport commissioner Jacques Barrot issued an ultimatum to   us  airliners. Barrot said  us  carriers should join the  eu  emissions trading scheme or they had to set up an equivalent system in the  us. 
  The current decision is likely to fuel an already brewing environmental dispute between the  eu  and the  us  which is refusing to let airlines join a carbon trading scheme (see 'Polluting airlines have a supporter',  Down To Earth, June 15, 2007). The International Air Transport Association also said 170 countries opposed the move.
  "It's possible to imagine reducing the number of flights," Barrot said. He even added a member of the  us  Congress' environment committee said a deal would be possible after the Bush administration ends. He asked the  us  to lift restrictions on foreign ownership of airlines and accept  eu  security procedures. The  us  and  eu  will begin negotiating a second phase of their "open skies" agreement in May 2008. 
   eu  airlines will also join the emissions trading scheme in 2012, which could add up to 13 (about  us $30) to the price of a return flight tickets as carriers buy carbon credits. The  eu  carbon emissions trading scheme has an economic angle too.  eu  airlines want foreign airlines to follow the same environmental standards they have to meet. European carriers want foreign rivals co-opted on to the scheme because airlines who refuse to buy carbon credits will offer lower fares.  eu  says all airlines flying in and out of the continent must get carbon credits.
