The Blue Economy: The Next Frontier in Global Growth

The Blue Economy emerges from the ocean and will create a new level of economic opportunity for those who are able to develop it. Similar to how the Green Energy Revolution has transformed the energy markets and the structure of industries and capital allocation over the last ten years. The Blue Economy is based on the concept of utilizing ocean resources sustainably. Thus, it has the potential to create a major economic transformation throughout the 21st Century.

What Is the Blue Economy? From Fisheries to Fintech

According to its basic definition, the Blue Economy comprehensively incorporates all aspects of economic activity that involve the seas, oceans, and coastal areas and highlights the necessity of responsible and sustainable usage of ocean resources for the benefit of future generations as well as today (ie, providing long-term employment/opportunities), through the creation of sustainable livelihoods. Multiple factors can help define what constitutes a “Blue Economy,” including:

• From the view of the World Bank, the “Blue Economy” represents the responsible and sustainable use of marine resources by supporting the development of robust ocean economies, leading to sustainable job creation and higher-quality livelihoods while maintaining the integrity of ocean and coastal habitats.

• Some definitions tend to expand to include freshwater ecosystems, which widens the definition even further to include a comprehensive view of the environment and the communities that depend upon it for their well-being and quality of life.¹

Historically, the ocean economy encompasses sectors that are visible to the mainstream, such as fisheries, shipping, shipping ports, and coastal tourism. These sectors make up the bulk of what is considered in terms of marine economics. With the rise of ideas such as the Blue Economy, traditional ocean economies are now being redefined to include “non-traditional” and emerging ocean economies, including marine renewables (offshore wind, tidal, and wave power), aquaculture and sustainable “blue foods”, marine biotechnology, seabed minerals (under a regulated framework), and ocean connected fintech and data services.

Every major sector of the ocean economy is being impacted by advances in digital technology. The use of blockchain-enabled supply chains for sustainable seafood or the creation of ocean data aggregators for the valuation of natural capital are just two examples that demonstrate the ability of digital technology to expand the scope of traditional blue sectors to encompass the broader knowledge economy.

The Scale of the Opportunity: A $3-5 Trillion Global Market by 2030

There are numerous estimates by expert organizations worldwide for the ocean (or “blue”) economic potential of the blue ocean economy and how it will continue to grow rapidly in this fast-developing sector. International organizations, from the World Bank to the International Energy Agency to the United Nations Environmental Programme (UNEP), estimate that the ocean economy may double to $3.0-5.0 trillion by 2030, based on current innovation cycles and if sustainability is achieved.²

If the Blue Economy were a country, it would rank among the world’s top economies in terms of aggregate output. Based on the latest OECD analysis, the ocean economy generated approximately US$2.6 trillion in gross value added globally in 2019 and provided millions of jobs worldwide. Projections under “high-end” (favourable) scenarios indicate the potential to grow nearly fourfold by 2050.

• Ocean trade and transport accounted for approximately $2.2 trillion in global ocean trade in 2023, which emanates with a strong services component tied to freight and tourism.³
• Coastal and marine tourism is a growing segment across small islands and emerging economies.⁴
• Fisheries and aquaculture are central to food security, which provide approximately 20% of global animal protein intake and supporting livelihoods.⁵

How Sustainability and Profitability Can Coexist

Sustainability is not treated as an add-on in the Blue Economy like it is in most other marine industries, but rather viewed as the foundation for all activities. In other marine industries, sustainability was almost always a result of economic exploitation, leaving only damage and degraded ecosystems or services available to develop new industry options.

In contrast, when developing the Blue Economy, there needs to be a focus on finding a way to ensure that environmental sustainability exists as well as economic development. In addition, it is now considered an increasingly important need to develop sustainable ocean-based economies; if an economy is built upon a degraded marine environment, it will collapse and lose its economic revenue potential.

The central principle around which the Blue Economy is based is referred to as natural capital. There are three types of benefits provided by oceans through ecosystem services:

• Carbon sequestration, especially in areas such as coastlines, including coastal blue carbon systems (mangroves and seagrasses). These three areas are considered to be vital contributors to climate change mitigation strategies.⁶

• The potential for fisheries productivity and food security. However, due to unsustainable practices, many fisheries have exceeded their biological sustainability boundaries, which has contributed to increasing calls to action for increased governance and sustainable fishery practices.⁷

• Coastal protection from storm surges and rising sea levels.

Investors and policymakers are beginning to embrace this way of thinking of ocean health as an economic capital. The integration of ocean-based metrics into Environmental, Social, and Governance (ESG) frameworks is emerging, along with the introduction of blue bonds as a mechanism for funding ocean conservation activities tied to desired long-term economic results.

Case Studies: Pioneers in the Blue Economy

Norway: A Maritime Powerhouse with Sustainability at its Core

The Blue Economy of Norway is shaped by its geographical location and its history, with the ocean area making up 6 times Norway’s land area, and its coastline being part of how Norwegians identify as a nation. The marine industries represent a significant portion of Norway’s GDP and employment.⁸

Key components of the Norwegian Blue Economy are:

• Traditional marine industry sectors (i.e., commercial shipping, seafood, offshore oil/gas – transitioning toward cleaner forms of energy)
• Innovation in the area of sustainable shipping (i.e., Norway’s ongoing efforts to establish zero emission cruise ship operation within UNESCO-approved fjords and support for hybrid propulsion system development.⁹
• Ocean accounting for the purpose of measuring ocean contributions to national economies using state-of-the-art satellite accounts.¹⁰

Norway’s combination of marine industry tradition, coupled with innovations, illustrates the opportunities for developed economies to simultaneously achieve marine economy growth and climate change mitigation objectives.

Indonesia: Maritime Strategy Meets Implementation Challenges

As an archipelagic nation with many islands, Indonesia has great untapped marine resources.  Indonesia’s Blue Economy Roadmap represents an attempt to focus on a strategy to maximize those marine resources.

Despite this focus on marine resources, there are still many obstacles preventing them from reaching their full potential in the local economy.  Research shows that although many industries (like maritime transport and ocean energy) can contribute to local economic growth and create jobs, these opportunities are limited by the lack of infrastructure, inadequate governance, and expectations that they will be operated sustainably.¹¹

For Indonesia to achieve its goal of creating equal and sustained growth will require improving conditions for all sectors that directly and indirectly protect and benefit coastal communities, who are stewards of their marine environments.

Seychelles: Blue Bonds and Small Island Innovation

The Blue Economy is likely to be adopted most easily by small island countries. The ocean serves not just as an economic resource for these nations but as their main source of survival. In 2018, the Seychelles became the first country in the world to sell a sovereign “blue bond” with a total value of $15 million, which will be used to support marine conservation and manage sustainable fishery practices, as well as to provide coastal infrastructure that can withstand changes in weather due to climate change.

This new instrument is setting the stage for others in the small island economy to follow their example of using capital markets to finance ocean health while generating positive returns from an economic standpoint.¹²

The ESG and Investment Angle — Ocean Health as Natural Capital

There is an increase in investor demand for sustainable ocean projects among various groups of investors, such as Pension Funds & Sovereign Wealth Funds. Various types of Blue Finance, including Debt for Nature Swaps, ESG Bonds, and Blended Public – Private Structures, are emerging as methods of closing the current Finance Gap, which currently represents only a small percentage of total capital needed for ocean protection vs what is currently being financed.¹³

Framing ocean ecosystems as Natural Capital is a key element of this shift because by framing ecosystems this way, continuous value can be generated if they are properly managed, therefore creating a new form of investment for long-term profitability. Development institutions and some Investment Banks have integrated Oceanic Risk Assessments into their macroeconomic/sustainability assessments, demonstrating that marine ecosystems represent Systemic Risks to Food Supply, Trade and Climate Resilience.

Conclusion: Blue Growth and Global Prosperity

The Growth of the Blue Economy is not only an academic phenomenon: it has also been driven by real market signals, government policies, and investors wanting to invest in the Blue Economy. The ocean has the potential to create an additional US$3–5 trillion in economic activity by 2030 and will be one of the most underutilized sources of growth potential in the world. Marine transportation, aquaculture, renewable ocean energy, and ocean-based innovation will drive the development of new global business models and industries. The main opportunity and challenge for the Blue Economy will be to align the financial benefits of business with the environmental sustainability of the oceans that support those benefits.
