Spotlight on China – the 2nd largest source of passenger related aviation emissions in May 2023.

  • In May 2023, passenger related aviation emissions from China were estimated at 7.32m tonnes, 5% below pre pandemic levels in May 2019.
  • Currently aviation emissions from China are not covered by any compliance scheme.
  • Domestic services are the largest contributor to China’s aviation emissions; since the pandemic, international services have been slower to return, thus domestic services represent a higher contribution to total emissions in percentage terms.
  • China Southern Airlines is the largest emitter of aviation emissions from China over the past 12 months, followed by China Eastern Airlines.
