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)

5% Growth in Emissions from International Shipping Sector Recorded in 2021
|Curb the growth of shipping emissions||The 5% growth indicates an urgent need to decelerate the rise in shipping emissions.|
|Implement effective carbon policies||This growth rate necessitates more robust carbon mitigation strategies.|
|Promote sustainable shipping practices||Increasing emissions suggest a need for more environmentally friendly shipping practices.|
The 5% increase in emissions from the international shipping sector in 2021 is a red flag, necessitating immediate action to curb this trend. Effective carbon policies and sustainable shipping practices need to be prioritized to counteract this surge.
Global Shipping Contributes 3% to Worldwide Greenhouse Gas Emissions
|Address shipping’s GHG contribution||The 3% global share indicates shipping’s significant contribution to GHGs.|
|Prioritize low-GHG propulsion technologies||A transition to low-GHG shipping tech is crucial for emission reduction.|
|Advocate for stricter GHG regulations||This level of GHGs calls for tighter emission standards and regulations.|
Global shipping contributes 3% of worldwide GHGs, revealing a critical area for climate change mitigation. The adoption of low-GHG propulsion technologies and stricter emission regulations are integral to addressing this significant environmental impact.
