Aviation pollution set to go sky-high

Aviation will account for five per cent of the world’s carbon emissions by 2050, according to a climate change study by researchers at

(MMU).

The scientists at MMU’s Centre for Air Transport and the Environment (CATE) calculated C0₂ emissions based on traffic predictions from sources including the International Civil Aviation Organisation. In 2000, air traffic contributed two per cent of global carbon emissions, but that figure could grow to five per cent by 2050.

The forecasts account for improvements in technology and air traffic management as total air traffic is predicted to increase by six to eight times 2000 levels by 2050. But the researchers say technological solutions to increased pollution lag well behind growth of the industry.

CATE’s David Lee, Professor of Atmospheric Science at MMU, said, "This research confirms the message from the Aviation White Paper that the aviation sector is forecast to make up a considerable proportion of global emissions in the future.
