November 10th, 2025 – As world leaders, policymakers, and stakeholders gather in Belém, Brazil, for COP30, new research from B Lab reveals that scaling the current practices of Certified B Corporations across the economy could reduce global warming by 0.5°C by 2100, prevent 600,000 deaths from extreme heat, and lower extinction risk for thousands of species.

The new whitepaper, released today by B Lab, demonstrates that more than 10,000 B Corps are leading the way in adopting practices across circularity, environmental stewardship, and climate action, and achieving measurably better outcomes than their peers.

The B Corp Movement Set Sail for Folkemødet

Each June, the small island of Bornholm transforms into Denmark’s largest gathering for democracy, values, and political dialogue: Folkemødet. This year, the Nordic B Corp community showed up in a different way: By sea.

Together with B Corps, allies and friends, B Lab Nordics boarded the historic schooner Mira and sailed to Bornholm. We wanted to bring our message into the heart of national debate: that business can, and must, be a force for good.

A call to policymakers: Recognize businesses driving change

At Folkemødet, many conversations revolve around the future of society, climate, and economy.We were there to add a clear voice:

  • Yes, B Corps exist and they’re already doing the work many only talk about.
  • Yes, we believe in triple bottom lines where social and environmental responsibility stands alongside financial health.

  • And yes, regulation matters but we think those not taking responsibility should carry the documentation burden, not the ones already leading the way.

Voluntary standards like the B Corp Certification show what’s possible. But we need political will, incentives, and frameworks to help make good business the norm, not the exception.

Impact on board

Our schooner became a space for a packed Friday program with events centred around redefining the role of business in society:

  • Social run and ocean dip with our friends from Meyers

  • Talk on Good Money with Merkur Andelskasse, Planetary Impact Ventures, and Klimate

  • Imagination workshop with MäRK Cph

  • Green transition panel featuring voices from Rudolph Care, Sinatur, Plandent, Meyers, and Round

  • Treasure hunt for the sustainable bottom line with ESG4Business

It was personal. It was political. It was about redefining the role of business in society.

This is just the beginning

We left Bornholm with stronger connections, new allies, and a shared sense that the B Corp movement belongs in every conversation about the future. We’re not here to do business as usual. We’re here to help shift the entire system.

Thank you to everyone who came aboard (literally and figuratively).

Let’s keep the wind in our sails.
