New Report: Tackling the Global Risk of Polluting Shipwrecks

We’re pleased to share the release of a new report from Lloyd’s Register Foundation and Project Tangaroa. Project Tangaroa is a global initiative focused on the urgent issue of potentially polluting wrecks (PPWs) left behind by the World Wars. Many of these wrecks still contain oil, munitions, and other hazardous materials, and as they corrode over time, they pose increasing risks to marine environments and coastal communities.

These wrecks are often located near vulnerable coastal populations, marine protected areas, important fishing grounds, and even World Heritage sites, making the need for action even more urgent.

Supported by Lloyd’s Register Foundation, Project Tangaroa was established by Waves Group and The Ocean Foundation to bring together global experts in developing international standards and protocols for managing these potentially polluting wrecks (PPWs).

The newly published report provides in-depth analysis and expert insight that underpins the Malta Manifesto, released in June 2025. It marks a significant step forward in shaping international cooperation to address this global threat, with contributions from marine scientists, maritime archaeologists, salvage professionals, and other specialists.
