The International Civil Aviation Organization (ICAO) said the target, agreed after five days of U.N.-led talks in Dubai, called for a 2030 percent reduction in carbon emissions by using clean energy sources such as sustainable aviation fuel by <>. The target ranged from five to eight percent in an earlier draft.

The United States said at the closing session of the meeting, which took place ahead of next week's COP28 climate summit, that the aim was to send a "clear and positive signal" to the financial community, which must invest in new clean energy projects.

Aviation is estimated to contribute between two and three percent of global carbon emissions. Sustainable aviation fuel is essential to reducing these emissions, but it is expensive and accounts for less than one percent of total global jet fuel.
