Blue Bonds: Financing Ocean Conservation and Sustainable Development

The extensive biodiversity crisis and ocean conservation have garnered significant attention recently, particularly regarding the marine ecosystem and water sustainability. Approximately 71% of the Earth's surface is composed of water bodies. In contrast, the Sustainable Development Goal (SDG) linked to water conservation, SDG 14, which addresses life below water, is the most underfunded amongst the 17 SDGs. Blue bonds play a pivotal role in addressing water scarcity, conserving the marine ecosystem, and ensuring the availability of clean water for consumption. This chapter examines how blue bonds revolutionise the sustainability of ocean economies, particularly addressing the issue of water scarcity in developing economies located near coastlines. The ocean economy has enormous potential in terms of returns generated from investments made under climate financing. In terms of yield benefits, investing USD 2–4 trillion in such projects is expected to generate over USD 8 to 23 trillion in the next 30 years. This chapter critically discusses the case studies of Blue Bond-issuing countries, namely the Seychelles, the Nordic countries, China, Indonesia, and Belize. It discusses how AI and Fintech are being utilised to measure the impact of issuing Blue Bonds. Investors interested in sustainable projects tend to prefer small-scale bonds, unlike the Seychelles blue bond, which is small-scale but has a high transactional cost. The challenges associated with Blue Bonds typically stem from the use of proceeds, which often require repaying investors regardless of the project’s success. The environmental impact of blue bonds is evaluated, and a future scope of research is suggested to improve transparency, standardized reporting formats, and enhance global collaboration.
