International aviation carbon dioxide emissions totaled 420 million metric tons (MtCO₂) in 2022, accounting for roughly six percent of global transportation CO₂ emissions that year.
International aviation emissions more than doubled between 1990 and 2019, to reach a record high of 619 MtCO₂. The outbreak of COVID-19 and subsequent travel bans caused aviation emissions to plummet more than 50 percent in 2020 to levels last observed in the mid 1990s. Although emissions rebounded in the following years, they remained well below pre-pandemic levels.
