This is the view of the Confederation of British Industry (CBI), following a recent report.
By imposing a global system, the aviation industry would control future levels of carbon dioxide emissions in a "cost-effective" manner while preventing "damaging leakages to other countries," the report concluded.
John Cridland, deputy director-general at the CBI, commented: "The best way for the world's aviation industry to meet its climate obligations is through a global cap and trade scheme.
"Such a scheme would include all airlines, removing scope for leakage of emissions from one country to another, and would run with, not against, the grain of this international industry."
Last week, the secretary of state for energy and climate change, Chris Huhne, backed plans to reduce the EU's carbon dioxide emissions by 30 per cent by 2020 instead of by 20 per cent, as is currently agreed.
