Navigating the International Marine Organization's Green Passport

by Matt Thorn

Executive Summary


“Green Passport” is the alternative name for the International Certificate of Inventory of Hazardous Materials. These certificates are carried by non-military vessels operating in international waters and document the type, quantity, and location of non-cargo hazardous materials such as asbestos, PCBs, and heavy metals contained within them, either as a result of their initial construction or subsequent modifications.

The purpose of Green Passport is to identify the hazardous materials onboard a ship, including quantities and locations. This, in turn, can aid in the decommissioning of ships because ship recyclers can develop dismantlement plans that protect human and environmental health based on the specific hazardous associated with the hazardous materials on board.


The requirement for Green Passports was created by the 2009 Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships. 64 nations are signatories to the Convention and, though it has not yet come into force internationally, its requirements have been adopted by many members. The European Union, for instance, as part of its 2013 EU Ship Recycling Regulation, requires all EU-member flagged ships to have Green Passports as of December 31, 2018, and all international ships that wish to dock at EU ports, to have an accurate and up to date Green Passport aboard by 2020.
