The "Tony deBrum" Declaration (2017) is a call for ambitious progress within the International Maritime Organization (IMO).

The “Tony deBrum” Declaration, an initiative launched by France, represents a call for ambitious progress within the International Maritime Organization to regulate shipping-related greenhouse gas emissions. These emissions represent 3% of the global total and could increase by 50 to 250% in 2050.

The Tony deBrum Declaration was signed by 36 countries at the 2017 OPS. In March 2018, 49 countries signed the Declaration before the start of the IMO negotiations.

The strategy for reducing greenhouse gases emitted by shipping was adopted by the IMO in April 2018.
