1% of people cause half of global aviation emissions – study

Frequent-flying “‘super emitters” who represent just 1% of the world’s population caused half of aviation’s carbon emissions in 2018, according to a study.

Airlines produced a billion tonnes of CO2 and benefited from a $100bn (£75bn) subsidy by not paying for the climate damage they caused, the researchers estimated. The analysis draws together data to give the clearest global picture of the impact of frequent fliers.
