The blue economy is the sustainable use of ocean resources for economic growth, improved livelihoods and jobs while preserving ocean ecosystem health. Blue growth is the FAO’s narrower term for the sustainable development that results from ocean, wetland and coastal economic activities while minimizing environmental degradation.
How do major institutions define the blue economy?
The World Bank defines the blue economy as the sustainable use of ocean resources for economic growth, improved livelihoods and job creation while preserving the health of ocean ecosystems. The United Nations echoes this definition and adds that a blue economy prioritizes all three pillars of sustainability: environmental, economic and social. NOAA describes the term as fluid in its definition, ranging from being directly equivalent to the ocean economy to including aspects of sustainability.
The World Bank’s definition is the most widely referenced in policy documents and investor materials. When you cite a definition in a pitch or grant application, the World Bank’s wording carries the most recognition. The UN’s framing adds the social pillar explicitly, which matters when you are addressing equity or community impact in your narrative.
What does blue growth mean and where did the term come from?
Blue growth is defined by the FAO as sustainable growth and development emanating from economic activities in oceans, wetlands and coastal zones that minimize environmental degradation, biodiversity loss and unsustainable use of living aquatic resources. The FAO’s Blue Growth Initiative was established to carry out this definition across four components: marine and inland capture fisheries, aquaculture, livelihoods and food systems, and economic growth from ecosystem services.
This is not a generic synonym for the blue economy. It is a specific FAO framework with named components and measurable targets. If you see “blue growth” in an FAO document, it refers to this structured initiative, not to a loose policy label.
How does the European Union distinguish blue growth from the blue economy?
The EU uses blue growth to describe the sustainable development of ocean-based economic activities, while the blue economy refers more broadly to all economic activities related to oceans and coasts. The EU’s Blue Growth Strategy frames growth as the outcome of managing ocean sectors sustainably, whereas the blue economy is the overall system those activities sit within.
In practice, EU policy documents use “blue growth” when discussing the trajectory of development and “blue economy” when describing the sector landscape. If you are writing for an EU audience or citing EU strategy documents, this distinction matters for precision.
Which sectors does the blue economy include and how large is it?
The World Bank’s blue economy portfolio exceeded $11.1 billion in active projects as of FY25, spanning sustainable fisheries and aquaculture, circular economy and solid waste management, sustainable coastal tourism, maritime transport, offshore renewable energy, and integrated coastal and marine ecosystem management. The UN estimates that the world’s coastal populations contribute about $1.5 trillion per year to the global economy, with expectations of roughly $3 trillion by 2030.
| Institution | Definition focus | Key scope or figure |
|---|---|---|
| World Bank | Sustainable use of ocean resources for growth, livelihoods and jobs | $11.1 billion portfolio (FY25) |
| FAO | Sustainable growth from ocean, wetland and coastal activities | 10–20 million tonnes capture fisheries target |
| NOAA | Emerging ocean economy inclusive of Great Lakes, evolving for sustainability | Descriptive term for multi-sector activity |
| UN | Blue economy prioritizes environmental, economic and social pillars | $1.5 trillion coastal contribution per year |
These figures anchor the concept in concrete scale. The World Bank portfolio tells you where institutional capital is flowing. The UN estimate tells you the size of the market your venture enters.
What are the main criticisms of blue growth?
Critics argue that blue growth can become a label for economic expansion without enforceable environmental limits. The World Bank’s own documents acknowledge there is no globally accepted definition of the blue economy, which means the term can be stretched to justify activities that do not actually preserve ocean health. The FAO’s blue growth definition explicitly requires minimizing environmental degradation and biodiversity loss, which is a stricter bar than some uses of the term.
When you use either term in a pitch, be ready to show how your venture meets the sustainability criteria. A vague claim of “blue growth” without specifics on environmental impact will not satisfy a grant-maker or an investor who has read the FAO’s definition.
How do ocean economy, blue economy and blue growth differ in practice?
NOAA uses ocean economy for the sum of all economic activities of ocean-based industries plus assets, goods and services from marine ecosystems. It uses blue economy for an emerging, developing ocean economy that conserves resources for future generations and reduces pollution. Blue growth, as the FAO uses it, is the sustainable development outcome from those activities.
In practice, ocean economy is the descriptive term for current activity. Blue economy adds a sustainability lens to that activity. Blue growth names the development trajectory you are pursuing. Use ocean economy when describing what exists today, blue economy when framing the sustainable version of that system, and blue growth when naming your specific contribution to sustainable development.
How large is the FAO’s blue growth target?
The FAO estimates that implementing its Blue Growth Initiative will eventually contribute 10 to 20 million tonnes per year from capture fisheries, valued at $50 to $100 billion, and 50 to 100 million tonnes per year from aquaculture. It also estimates contributions of around 10 million tonnes from non-food uses and 15 million tonnes from waste food.
These targets are rarely cited alongside the World Bank portfolio figures, but they give you a sense of the scale the FAO expects from its framework. If your venture touches fisheries or aquaculture, aligning your impact narrative with these targets makes your case legible to funders who follow FAO guidance.
Which term should a founder use when pitching investors?
Use blue economy when describing the overall market and sector landscape, because it is the term investors and institutions recognize. Use blue growth when you are specifically framing your venture’s contribution to sustainable development, because it signals alignment with the FAO and UN sustainability pillars. Avoid using them interchangeably in a pitch deck, because mixing the terms can make the narrative look imprecise.
