In this report the World Ocean Initiative assesses the challenges facing key sectors in the ocean economy, including seafood, shipping, tourism and renewable energy. We look at the role of banks and investors in financing the transition towards clean, low carbon technologies, as well as opportunities in data and analytics. We examine solutions to marine plastic pollution from source to sea, and the ocean’s potential to remove carbon from the atmosphere and increase resilience to the impacts of climate change. Drawing on the latest data and in-depth interviews with experts in government, business, finance and conservation, this report provides valuable insights for all stakeholders working to achieve a sustainable ocean economy.
