Rethink Carbon
Rethink Codes is an AI-powered platform that transforms the management of Woodland Carbon Code and Peatland Code projects. It streamlines workflows, automates stakeholder queries, and integrates real-time digital monitoring, reporting and verification (DMRV) - accelerating project delivery and reducing costs.
By combining smart administration, collaborative tools, and performance analytics, Rethink Codes brings greater transparency, consistency, and trust to the UK’s nature-based carbon markets, supporting the growth of a voluntary carbon credit system aligned with national climate goals.

The Opportunity
With the global market for nature-based carbon infrastructure projected to reach $1 - 1.5B by 2030, Rethink Codes targets the UK and international opportunity with a scalable SaaS model for code administrators, project developers, and validation bodies.
Next Steps
Rethink Codes will launch with Woodland and Peatland Code administrators in the UK in 2026. Later that year, we'll onboard project developers, validation bodies, and DMRV data providers. With a proven UK deployment, we'll drive commercial growth, build case studies, and expand into international markets and other nature-based codes.
The Team
Rethink Carbon is led by a cross-functional team with deep expertise in software, land management, GIS, and product delivery. We’ve previously launched the Rethink Carbon platform and have built strong relationships across the sector, positioning us to deliver trusted digital infrastructure for the future of nature-based carbon markets.
