6 de abr. de 2022 · Aviation contributes an estimated 2.4% of global annual CO 2 emissions, most of it from commercial travel. However, Klöwer said, “Most people think of warming in terms of degrees, not tons of carbon emitted, so we wanted to calculate that.” Air travel contributes 4% to global warming, more than almost all countries.
In 2022 aviation accounted for 2% of global energy-related CO 2 emissions, having grown faster in recent decades than rail, road or shipping. As international travel demand recovers following the Covid-19 pandemic, aviation emissions in 2022 reached almost 800 Mt CO 2, about 80% of the pre-pandemic level.
1 de nov. de 2020 · Aviation is one of the most energy-intense forms of consumption, and has in the past been characterized by strong growth, with estimates that emissions have increased by a factor 6.8 between 1960 and 2018 ( Lee et al., 2020 ). Industry estimates prior to COVID-19 have suggested a further tripling between 2020 and 2050 ( ICAO, 2016 ).
