2030 Marine Biodiversity and Ocean Health Breakthrough and Roadmap

The 2030 Marine Biodiversity and Ocean Health Breakthrough and Roadmap provides specific near-term actions and milestones for the maritime sector with respect to ocean health and biodiversity, and creates a shared vision for climate and nature across all stakeholders. By utilizing resilient solutions and an equitable approach, the Roadmap details how maritime actors can minimize impacts on marine biodiversity whilst tackling the triple global crises of climate change, biodiversity loss, and pollution.

The Marine Biodiversity and Ocean Health Roadmap provides milestones for 2030, 2040, and 2050, as well as Actions required before 2030 to achieve these milestones. Milestones are identified under the following themes: Voyage and Port Planning, Emission Reduction, Efficiency, Pollution, Marine Spatial Planning and Marine Protected Areas, Ocean Policy and Governance, and Ocean Finance.

Milestones are aligned with international commitments and initiatives, including the Paris Agreement, Kunming-Montreal Global Biodiversity Framework, and the High Level Panel for a Sustainable Ocean Economy. Actions and milestones are identified by scale, at fleet level or sector level, and by sector relevance. Indicators are provided to help track progress against milestones.
