Thomas Crowther

Scientist. Trillion Tree Campaign Advisor. Problem Solver.

Thomas Crowther is a British scientist specializing in global ecosystem ecology and the chief scientific advisor to the UN's Trillion Tree Campaign. He is a tenure-track professor of Global Ecosystem Ecology at ETH Zürich where he formed the Crowther Lab. His work aims to generate a holistic understanding of the global scale ecological systems which regulate the Earth's climate.

After his Ph.D., Tom received a postdoctoral fellowship from the Yale Climate and Energy Institute, to pursue his postgraduate research at Yale University. In 2015, he was awarded a Marie Curie fellowship to research the impact of carbon cycle feedbacks on climate change at the Netherlands Institute of Ecology (NIOO).

Through the Crowther Lab, teaching, talks, and collaboration with the World Economic Forum, Tom seeks to build consensus and uncover and advance straightforward solutions to address climate change and biodiversity loss.

Progress in the Quest for Climate Change Solutions

The conservation and restoration of natural ecosystems are among our most effective strategies to help in the fight against biodiversity loss and climate change. Managing ecosystems effectively requires intricate knowledge of the organisms that regulate our climate.  The Crowther Lab is dedicated to analyzing the Earth’s ecological systems to understand how best to preserve and restore biodiversity around the world, and the benefits that brings for carbon capture and human wellbeing. This can be achieved through the conservation and restoration of forests, grasslands, and peatlands, along with the holistic management of agricultural soils to promote diverse mixtures of species. This is the idea behind the Trillion Tree Campaign ( In this talk, Tom shows how his team at Crowther Lab, with the support of the World Economic Forum and it’s Trillion Tree Campaign, are sharing data and scaling solutions to enable citizens everywhere to be a part of the solution.
