International shipping

In April 2018, the International Maritime Organization (IMO) agreed to reduce GHG emissions by at least 50% by 2050 compared with a 2008 baseline, with carbon intensity reduction targets for 2030 and 2050.

CO2 emissions from international shipping in the Net Zero Scenario, 2000-2030


CO2 emissions from international shipping began rebounding in 2021 from a dip in 2020

In 2021 international shipping accounted for ~2% of global energy-related CO2 emissions. While measures approved by the International Maritime Organization are likely to curb the rise of emissions over the 2020s, greater policy ambition is needed to steer the maritime shipping sector onto the pathway in the Net Zero Emissions by 2050 Scenario, which entails an almost 15% reduction in emissions from 2021 to 2030. Technological innovation, supportive policies and collaboration across the value chain are needed to drive the adoption of low- and zero-carbon fuels and technologies for oceangoing vessels.
