Cambridge Centre for Carbon Credits (4C)

We launched the Cambridge Centre for Carbon Credits (4C) in early November 2021.  Our first goal is to scale up the supply of deforestation avoidance carbon credits in order to halt tropical deforestation as soon as possible. We have published software prototypes and original science on the topic.

Our Approach

The Cambridge Centre for Carbon Credits (4C) is creating digital tools and a trusted, decentralized platform to help purchasers of carbon credits to confidently and directly fund trusted deforestation avoidance projects, bringing together corporate funders and conservationists via automated and transparent smart contracting tools.

If you're a conservation organisation interested in using our digital carbon credits calculation platform to issue robust credits, please get in touch. We are currently operating on moist tropical forests, with a view to expanding out to other forests (seasonal dry, temperate, and coastal mangroves) in a future phase.

If you're a Web3 developer who wants to help with the development or integration of our Tezos smart contracts, then please see our prototype code and paper in ICBC2024.

Fixing the biodiversity leak

27 February 2025

Members of 4C have joined with economics and conservation science colleagues in an opinion piece in Science highlighting the problem that efforts to safeguard and restore biodiversity in places which produce food or wood risk simply displacing that production elsewhere. Such leakage is acknowledged as a significant issue...

Scientific credibility for high-integrity voluntary carbon markets

We are excited to share this position paper from 4C on ‘ Scientific credibility for high-integrity voluntary carbon markets ’, based on our reflections on our work over the past three years, and setting out our hopes and ambitions for nature-based carbon credits and the Voluntary Carbon Market in 2025. We are encouraged by...

The Global Challenge

The world is facing simultaneous biodiversity and climate crises. Pressure is mounting from governments and the general public to rapidly roll out a global programme of well-executed nature-based solutions to sequester several giga-tons of carbon each year and protect biodiversity.

Over 100 world leaders at COP26 pledged to end deforestation by 2030. Our urgent challenge is figuring out how to verify that deforestation solutions are working, and tracking the associated carbon credits used to offset necessary emissions.
