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 are currently working on a prototype of a trusted nature based marketplace.

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 2023.

If you're a Web3 developer who wants to help with the development or integration of our Tezos smart contracts, then please also get in touch. We will be deploying on the Tezos ghostnet in Summer 2022, with wider availability later in the year. Now is the best time to tell us about your carbon credit needs.

The 'why' of 4C: Prof Keshav on the power of trees

14 August 2023

Prof Keshav, one of the directors of 4C, has spent the past decade reducing the carbon cost of energy, buildings and transport. But that's only part of the puzzle: we still need to remove carbon from the atmosphere. In this video, Keshav explains how forestry and nature-based solutions are a 'two-for-one', supporting biodiversity as well as removing carbon from the air.

Detectree2 - a new way to delineate individual tree crowns in tropical forests

23 May 2023

James Ball and colleagues have developed a computer vision method for delineating tree crowns in tropical forests from aerial RGB imagery, available as an open-source Python package.

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.
