B Corps Demonstrate Path to Reduce Global Temperature Rise by 0.5°C as Business Leaders Mobilize at COP30
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.
