World-first forest carbon mapping initiative


Vital data from a pioneering new initiative will support people around the world to understand the value of forests in tackling climate change.

GEO-TREES is a new global multimillion pound project that will collect ground data and validate carbon storage maps of the world’s forests.

Land vegetation stores a huge volume of carbon, and keeping it out of the atmosphere is essential to limit climate change. Mapping this vegetation supports researchers and practitioners to protect it from degradation.

GEO-TREES is the world’s first ground-based, open-access, equitably developed and funded reference system that supports accurate satellite observations of forest carbon stocks.

Professor Oliver Phillips and Professor Guy Ziv, both from the School of Geography, are collaborators on the initiative.

The project funds and supports data collection and practitioners on the ground, particularly in the Global South. Their vital data will help translate remote satellite estimates of forest structure into valid numbers of forest biomass density, enabling carbon to be mapped accurately across the world’s forests.

GEO-TREES aims to give representation, fair compensation and investment to partners in the Global South, many of whom have limited access to research funding. The project will also assist governments, policymakers and communities to understand its results.

Professor Phillips coordinates the global ForestPlots network, which is a key partner of GEO-TREES and serves on the project’s Executive Board. Professor Ziv is a Scientific Advisor to the project.

Both Professors participated in the GEO-TREES launch meeting at the Smithsonian Institution in Washington D.C. in May 2024, with colleagues from every inhabited continent.

Professor Phillips delivered a keynote presentation titled “The ground network experience, their contribution to GEO-TREES, and the challenge to make tropical forest science fairer.”
