“Education and love for nature are not always enough to drive systemic change. We need to speak the language the whole world understands: the language of money.”

Let’s decode these words with an example. Whales consume large amounts of krill, small fish, and marine organisms, storing the carbon from this food within their bodies. They also release nutrient-rich waste, which fertilizes the water and promotes the growth of phytoplankton (microscopic, plant-like organisms). These organisms absorb carbon dioxide from the atmosphere and serve as food for the next generation of krill, sustaining the cycle. This way, it is estimated that a single whale provides about $2 million in ecosystem services during its lifetime. In other words, around $2 million would need to be spent elsewhere to offset the same amount of carbon without that whale. Isn’t it interesting?
Similarly, seagrass can absorb carbon 35 times faster than a rainforest, yet its role in mitigating climate change is often overlooked. These are just a few examples.
In 2015, United Nations Member States came up with a very good idea of a global blueprint for peace and prosperity of the planet. These were Sustainable Development Goals (SDGs). Among these 17 SDGs, Goal 14 (Life Below Water) focuses specifically on protecting oceans. Its objective was to ensure the conservation and sustainable use of oceans and marine resources. The goal outlined 7 specific targets that aimed to support a sustainable ocean economy by the year 2030.
However, progress toward achieving these targets has been relatively slow, and SDG 14 is the least funded of all 17 goals, receiving less than 1% of total finance. While there have been modest gains in improving the sustainability of fisheries and an increase in the number of Marine Protected Areas (MPAs), these protected zones currently account for only about 7.5% of the world’s oceans.
It is not only about the finances. Another major barrier for investors is the lack of standardized metrics to evaluate ocean-related sustainability outcomes. While ESG frameworks for carbon emissions and land-based biodiversity are relatively established, measuring ocean health, such as marine biodiversity protection or sustainable fishing practices, remains complex. Even institutional investors acknowledge that the unique nature of ocean ecosystems makes risk and impact measurement more challenging than traditional environmental investments.
Coastal ecosystems such as mangroves, seagrass beds, and salt marshes do store significant amounts of carbon, which makes blue carbon a powerful nature-based climate solution. However, the blue carbon market is still in its infancy. By early 2025, fewer than 7 million blue carbon credits had been issued globally, and only a handful of projects were actively generating tradable credits. Existing projects cover around 2 million hectares of coastal ecosystems, while the global capacity is dozens of times larger.
Oceans cover over 70% of the planet’s surface and contain 97% of its water. More than 3 billion people depend on them for their livelihoods. Yet ocean-linked investments still represent only a fraction of global ESG capital. That gap is precisely why analysts and policymakers describe the blue economy as the next major ESG frontier.
Blue Finance: Financial markets have started developing instruments specifically designed to fund ocean sustainability projects. In April 2025, Laconic Infrastructure partnered with the Government of the Bahamas to launch a groundbreaking climate-finance initiative that monetizes the country’s vast seagrass ecosystems through a new financial instrument called Sovereign Carbon Securities. The project will generate verified blue-carbon removals by scientifically managing up to 150,000 km² of seagrass, converting the captured carbon into tradable financial securities for global investors.
Aligned with Article 6.2 of the Paris Agreement, the initiative is the world’s first Blue-Carbon Sovereign Carbon Securities transaction and aims to attract long-term investment, support climate action, and help the Bahamas progress toward its goal of becoming a net remover of atmospheric carbon by 2035. Financial institutions such as BNP Paribas also highlight the growing relevance of blue finance, noting that investor demand for ocean-related assets is increasing.
Ocean Energy: As the energy transition accelerates, oceans are becoming a major platform for renewable power generation. Wave energy, tidal power, and floating offshore wind are transforming the way coastal regions produce power. Projects like floating offshore wind farms and wave-energy systems demonstrate how ocean energy can provide stable, predictable power while reducing dependence on fossil fuels. Unlike solar and wind on land, marine energy systems can deliver consistent generation due to predictable tidal cycles and ocean currents.
Desalination: Water scarcity is pushing coastal regions to invest heavily in the water desalination equipment market. Jordan, one of the most water-scarce countries on Earth, launched the Aqaba–Amman Water Desalination and Conveyance Project in 2025. Among the largest desalination initiatives ever built, the system will produce around 851,000 cubic meters of potable water per day and transport it nearly 450 km inland to the capital city of Amman, helping address severe regional water scarcity.
Meanwhile, Dubai Electricity and Water Authority (DEWA) is deploying large-scale reverse-osmosis plants powered by solar energy and AI-driven optimization systems to improve efficiency and reduce carbon emissions. These facilities are part of Dubai’s plan to shift 100% of desalinated water production to clean energy sources by 2030.
Sustainable Aquaculture and Marine Biotechnology: As pressure on wild fisheries increases, the blue economy is witnessing a convergence between sustainable aquaculture and marine biotechnology. These two sectors are reshaping how the world produces food, medicines, and bio-based materials from the ocean.
Aquaculture already supplies more than half of the seafood consumed globally. The sector is now shifting toward more technology-driven and sustainable models. Offshore fish farms, AI-based monitoring systems, and alternative feed ingredients are helping reduce environmental impacts while increasing productivity.
Technology companies such as AKVA Group, which provides advanced recirculating aquaculture systems used in new land-based salmon farms in South Korea, illustrate how digital infrastructure and controlled environments are transforming seafood production. At the same time, marine biotech firms like Cyanotech Corporation are commercializing microalgae-derived compounds such as astaxanthin and spirulina for nutraceutical, pharmaceutical, and aquaculture applications.
Ocean Tourism: Coastal and marine tourism has always been a significant segment of the blue economy, but the industry is now shifting toward regenerative models that combine economic growth with marine ecosystem protection. Globally, coastal and maritime tourism supports about 52 million jobs, making it one of the most economically significant ocean industries.
According to the EU Blue Economy Report-2025, coastal tourism accounts for about 33% of the blue economy’s total gross value added and more than half of its employment, underscoring its central role in ocean-based economic activity. The sector is now pivoting toward sustainability-driven growth. In 2025, the Ocean Tourism Pact was launched at the Blue Economy and Finance Forum in Monaco to align tourism companies with marine conservation goals. The initiative seeks to scale sustainable coastal tourism models while supporting global targets to protect ocean ecosystems.
Governments are also investing in next-generation coastal tourism infrastructure. For example, Saudi Arabia’s AMAALA Triple Bay project, part of its Red Sea tourism strategy, is expected to create around 50,000 jobs and contribute roughly $3 billion to GDP , illustrating how regenerative coastal tourism is becoming a strategic economic development tool.
Over the past few decades, economic activities linked to the ocean have expanded rapidly. Since 1995, the ocean economy has grown 2.5 times, outpacing the 1.9-fold expansion of the world economy. Today, the global ocean economy is estimated to be valued at around $1.5 trillion, and projections suggest it could double by 2030. Much of this future expansion is expected to come from a wide range of industries and activities that depend on marine environments. So, the concept of the blue economy is achievable only when we see oceans beyond fishing and shipping.
