Developed by The Nature Conservancy in collaboration with Vizzuality and Bain & Company, the Blue Carbon Cost Tool (BCCT) is a first-of-its-kind platform that helps align investment with impact by revealing where blue carbon restoration is most needed, what it costs, and the potential carbon and community benefits.

The Blue Carbon Cost Tool brings financial transparency to blue carbon markets; helping policymakers, investors, and NGOs make data-driven decisions that align funding with real conservation impact. Already, it’s being used in New Zealand to assess financial feasibility of tidal marsh restoration projects; in the Virginia Coast Reserve seagrass project to support valuation for the upcoming first seagrass carbon credits; and will soon be used in India and Mexico to support project valuation and scope the financial feasibility of blue carbon projects.

Global reach
Covering over 400 modeled scenarios across nine countries, the tool reveals where conservation and restoration can have the biggest impact.

Smarter decisions
By combining scientific and financial data, the platform helps investors and policymakers identify true project costs and potential carbon returns.

Empowering action
Users can design custom projects, contribute data, and compare scenarios, ensuring decisions are grounded in evidence and aligned with local needs.



We focused on ensuring the platform not only conveys accurate cost and carbon benefit information but also empowers users to make informed, strategic decisions for conservation and restoration, bridging the gap between scientific complexity and actionable outcomes.
