A group of leading airlines has called for CO2 emissions from aviation to be included in the new global climate deal.
The Aviation Global Deal (AGD) coalition is keen to have international aviation emissions reflected in the new Copenhagen deal as it was not featured in the original Kyoto Protocol.
The group published a communique as a contribution to preparations by the UN International Civil Aviation Organisation, which stipulates that an aviation deal includes "genuine environmental benefits".
Speaking on behalf of the group, chief executive of Cathay Pacific Airways Tony Tyler said: "Aviation has a key part to play in reducing global emissions and for too long has been seen as part of the climate problem rather than part of the solution.
"We hope the work of our group will offer a practical industry-led solution that creates a level playing field and appeal to policy-makers, environmental groups and businesses."
The pledge follows Continental Airlines’ first successful test flight using sustainable biofuels.
