Foil Forward is structured to promote new business development in the marine technology sector.  Marine technology is a broad area of industry and innovation that is part of a larger sector – the blue economy.

The Blue Economy: Defined

The blue economy encompasses revenue generation activities from a range of ocean resources.  In this unique system, the development and extraction of ocean resources considers and emphasizes sustainable use of the ocean to preserve ocean ecosystems and enhance human quality of life.  

The core concepts in the Blue Economy are:

• Sustainable Use: Unlike other economies, the blue economy aims to balance economic benefits with the long-term health of the resource – in this case, the ocean. This concept is manifested as intentional action to mitigate damage to the ocean environment.
• Economic Growth: The blue economy aims to foster economic development and create opportunities for businesses and communities. It recognizes the significant potential of the ocean to contribute to global economies.
• Improved Livelihoods: A key goal is to enhance the well-being of people who depend on the ocean, including coastal communities, fishers, and those working in marine-related industries.
• Ecosystem Health: The blue economy acknowledges the vital role of healthy ocean ecosystems in supporting both human well-being and economic activity. It prioritizes the conservation, restoration, and protection of marine environments.

The World Bank defines the blue economy as the “sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem.” This definition encapsulates the core principles of this evolving economic model.

Beyond Traditional Industries

It’s important to understand that the blue economy is not just a new name for existing ocean industries like fishing and shipping. While these sectors remain important, the blue economy encompasses a much broader range of activities, including emerging sectors that offer significant potential for innovation and sustainable development.
