The European Union is to limit carbon dioxide emissions from aircraft, probably from 2010, the Financial Times reports Tuesday, with emissions trading the most likely route to be taken.

The European Commission will decide this autumn how soon aviation can be bought within the scheme.
But the FT says many questions remain to be answered, including whether the scheme will apply to all flights originating and terminating in the E.U., and how emissions will be measured.

Industry opinion in spilt.

British Airways, Chief Economist tells the FT emissions trading is "the most environmentally effective and cost effective" method of containing emissions, but the International Air Transport Association says it will put airlines operating in Europe at a disadvantage.
