As the world grapples with climate change and an economic downturn, new research from the World Resources Institute suggests that sustainable ocean-based investments will yield benefits at least five times greater than the costs.

Over the next 30 years, investing $2 trillion to $3.7 trillion globally across several sustainable ocean-based policy interventions would generate a net benefit of $8.2 trillion to $22.8 trillion, according to the report.

The investments focus on four key areas: production of sustainable protein from the ocean, maintaining mangrove habitats, increasing offshore wind production and decarbonizing international shipping.
