Blue Economy













Is the Blue Economy relevant for your organization?
Are you looking for new ways to offset your remaining CO₂ emissions?
Does your organization develop offshore projects and want to create ecological added value?
Are you investing in marine activities and want to make your environmental impact measurable?
Do you want to innovate with nature-based solutions in the marine environment?
Yes, then the Blue Economy offers your organization unique opportunities for CO₂ compensation and ecosystem restoration.


Why invest in blue?
The Blue Economy still holds enormous potential for reducing CO₂ and strengthening marine ecosystems. Our team is actively committed to harnessing this potential for tangible ecological and economic added value. We would be happy to do the same for your company.
Enormous CO2 potential
Blue carbon ecosystems like seagrasses and mangroves sequester 10x more CO₂ per hectare than tropical forests and can store carbon in marine sediments for thousands of years.
Multiple Use Innovations
Combine various marine activities in the same location: for example, wind energy + aquaculture + nature restoration. Maximize space utilization without harming nature.
Leveraging Ecosystem Services
Healthy marine ecosystems protect coasts, filter water, and provide an ideal habitat for commercial fish species – services that are also economically valuable.
Belgian expertise
Flanders is among the world leaders in offshore wind energy and a pioneer in multiple use of marine space – the ideal testing ground for innovative applications.

Frequently asked questions

Yes, you can! After taking steps to reduce your emissions, you can offset your remaining CO2 by investing in the Blue Economy. In addition to reforestation with carbon credits, you can, for example, invest in the restoration and preservation of blue carbon systems, such as mangroves and seagrasses, which are very effective at sequestering CO2. There is already a voluntary market for blue carbon credits, and in the future, more ways to invest in other marine ecosystems are likely to emerge.
The Blue Economy plays a crucial role in the conservation and restoration of marine biodiversity. Through sustainable fisheries, aquaculture, and the protection of vulnerable marine habitats, it helps prevent overexploitation and species loss. Initiatives such as marine protected areas and the restoration of coral reefs and mangroves are examples of how economic activity can be successfully combined with biodiversity goals.
The Blue Economy plays an increasingly important economic role in Flanders, accounting for 5.2% of its gross domestic product. The sector also plays a crucial role in key transitions, such as towards a circular economy, sustainable energy, and mobility. Through innovation and collaboration, the Blue Economy contributes to economic growth, job creation, and strengthening Flanders' position as a leader in sustainable development.
As a business, you can capitalize on the growing demand for sustainable marine products, such as responsibly sourced fish, seaweed, and marine biotechnology, by making your production and supply chains more sustainable. For example, by meeting certifications like MSC (Marine Stewardship Council) for sustainable fisheries, your company can gain access to markets that increasingly value sustainability, thereby improving your competitive position.
The Blue Economy plays a significant role in protecting coastal areas from the effects of climate change, such as rising sea levels and increasingly severe storms. Marine ecosystems like mangroves and seagrass beds offer natural protection by preventing coastal erosion. Your company can also invest in this, which not only helps protect coastlines but also enhances biodiversity and sequesters carbon. Additionally, sustainable marine projects, such as floating wind farms, contribute to an energy supply that is more resilient to climate change.
