The pre-existing policy environment in the Baltic Sea region, defined by national interests and implemented within sectoral silos, has historically constrained innovation and implementation of systemic measures to safeguard the fundamental bio-physical basis that sustains 60 million people and 10 nations forming this vibrant region; namely its waters, its land and its air. Existing measures tend to only address challenges within a single sector and/or locality, often leading the translocation of challenges elsewhere in the Baltic Sea Region or the emergence of new challenges in another sector.

This BONUS RETURN project will focus on eco-technologies that reconcile key conflicting challenges inhibiting sustainable development in urban and rural settings within the Baltic Sea Region whilst reducing nutrient enrichment and carbonization in water bodies.

Pilots in Sweden, Finland and Poland will be set up to test the most promising eco-technologies identified by the project. Envisaged project outputs include an evidence-based review of eco-technologies; innovative models comprising both nutrient and carbon cycling; sustainability assessments of selected eco-technologies; policy recommendations for promoting the eco-technologies; and market strategies for the most promising eco-technologies.

SEI is coordinating the project with the following partners:
