The International Civil Aviation Organization said countries "should not" apply aviation emissions trading systems to airlines of other countries

, "except pursuant to mutual agreement." A European Commission statement expressed "disappointment" and cited a lack of global consensus in insisting that the European Union "will not feel bound" to recognize other countries' veto rights should it add commercial aviation to the E.U. Emissions Trading Scheme. E.C. proposes to include all intra-E.U. flights--operated by both E.U. and non-E.U. carriers--by 2011, followed a year later by all international flights to and from E.U. airports.
