Head of Ocean Programme, Planet Tracker

Ocean health is of primary importance to our planet. Marine issues have a direct impact on climate and biodiversity, affecting billions of people whose lives and livelihoods depend on a healthy ocean. The top 50 investor holdings in the Global Seafood database account for more than $150 billion. But although it’s just one economic sector and a small fraction of global financial markets, fishing has a disproportionately large environmental footprint.

In our latest publication, we explore overfishing through an investment lens. We consider why it's a financially material issue, how it interacts with wider environmental and social risks, and what this means for asset owners seeking to invest responsibly over the long term.
