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. Only 11% of the world’s population took a flight in 2018 and 4% flew abroad. US air passengers have by far the biggest carbon footprint among rich countries. Its aviation emissions are bigger than the next 10 countries combined, including the UK, Japan, Germany and Australia, the study reports.
