International aviation carbon dioxide emissions totaled 492 million metric tons (MtCO₂) in 2023. International aviation emissions more than doubled between 1990 and 2019, to reach a record high of 625 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 have remained well below pre-pandemic levels. International aviation accounts for roughly six percent of global transportation CO₂ emissions.
