Initial IMO Strategy on the reduction of GHG emissions from ships

While it is the most efficient way to transport goods, the emissions from international shipping are projected to grow as a proportion of global emissions.

The Initial IMO Strategy on the reduction of GHG emissions from ships, or Initial IMO GHG Strategy, is the framework through which the International Maritime Organization (IMO) aims to reduce greenhouse gas (GHG) emissions from international maritime shipping. GHG emissions from shipping are about 3% of total GHG emissions, and under this strategy the IMO envisions their elimination within this century. However many companies and organizations say shipping should be decarbonized by 2050.

International shipping was not covered by the 2015 Paris Agreement, which seeks to limit climate change. With emissions from shipping expected to increase both in absolute and relative terms, there was pressure on the IMO to take action. In 2016, an agreement was reached to develop a strategy, which culminated in the adoption of the initial strategy in 2018. This is seen as a first step, with a revised strategy expected in 2023.

While the policy of the IMO, the strategy is not legally binding upon members. It suggests a variety of measures which can be adopted along different time frames for member states to adopt. The strategy also envisions cooperation through which more developed countries can support those less able to adapt.
