About Carina Thomassen
Carina Thomassen
Associate Expert, Waste and Marine Litter

Empowering communities and ecosystems through action on marine litter.

I am an Associate Expert at GRID-Arendal focusing on waste and marine litter. My work supports evidence-based initiatives that reduce pollution at its source, strengthen circular systems, and improve environmental health for both people and planet.

What I Bring

With a multidisciplinary background in environmental science and community development, I combine data analysis with stakeholder engagement to support holistic solutions to marine litter. I collaborate across sectors to design and implement projects that address the impacts of waste in vulnerable coastal and marine environments. My approach centres on inclusion, innovation, and a deep commitment to sustainable change.

My Focus Areas

  • Systems Intelligence & Project Stewardship
  • Collaborative Facilitation & Transformative Engagement
  • Catalytic Knowledge & Insight Generation
  • Immersive Storytelling & Strategic Communication

In My Own Words

″Tackling marine litter means working together—across disciplines, communities, and coastlines—to restore what connects us all.″
