The Nature Conservancy (TNC), together with its partners Vizzuality and Bain & Company, have launched the Blue Carbon Cost Tool (BCCT). The interactive tool is designed to assist NGOs, researchers, investors and policymakers in aligning investment decisions with environmental sustainability and community prosperity within the blue carbon market. “The Blue Carbon Cost Tool (BCCT) will enable smarter investing in blue carbon from the start – which will build the much-needed trust to unlock scalable investment opportunities.”The challenges facing blue carbon investmentCarbon markets could grow from their present $1-2 billion annually to $100 billion by 2030. Blue carbon projects, by contrast, store carbon while also enhancing coastal resilience, biodiversity and sustaining fisheries. The Blue Carbon Cost Tool aims to bridge this divide, bringing transparency and fairer pricing to support ecosystems, communities and long-term viability.
