Shipping Emissions Statistics:  Key Numbers

  • In 2021, international shipping emitted nearly 700 million metric tons of carbon dioxide (MtCO₂) into the atmosphere. This was an increase of roughly five percent from the previous year.
  • In 2021, international shipping accounted for ~2% of global energy-related CO2 emissions.
  • Some scientists have projected that maritime shipping could account for 17% of total annual CO2 emissions by 2050.
  • In 2021 emissions from the international shipping sector grew by 5%
  • Global shipping spews out 3% of worldwide greenhouse gases (GHG)
