Why WeForest

Current global efforts are not enough to keep global warming to the 2 °C as agreed upon at COP21. Global emissions must peak at the latest by 2020 and the excess carbon dioxide must be removed from the atmosphere now. A simple solution exists that will buy us time until a low carbon economy is available everywhere. Healthy and growing forests remain the best technology for removing excess carbon dioxide from the atmosphere.

Our vision 
We imagine a world where communities and nations sustainably manage their forests and natural resources for the benefit of our climate, our environment and humanity.

Our mission
Building upon corporate and scientific partnerships, WeForest empowers communities to sustainably advance and implement innovative, high standard, scalable and lasting solutions to restore forest landscapes.

Our values
The values that inspire our work are: Integrity, Transparency, Excellence, Collaboration, Passion, and Courage.

Our goal
Our goal is to successfully transform 250,000 ha of forest landscape by 2021, restoring  25,000 ha of forests (with an estimate of  25 million trees) demonstrating FLR best practices in different ecosystems and leading to the adoption of an international standard.

Trees are the best known ‘technology’ to cool our planet:

Why it matters

We plant trees and bring back forests in order to Make Earth Cooler.

Explore our approach

How it all started

The idea of WeForest came to Bill Liao in 2008 out of a thorough search for scientific evidence : Bill wanted to find a simple solution to the urgent issue of global warming. Marie-Noëlle Keijzer met Bill in 2009 and they decided to transform this idea into an NGO. WeForest has overtime developed a unique capacity to mobilize companies  (ranging from start ups to large multinationals) to engage their employees and millions of consumers in restoring the world’s forests.

Who We Are

Our team is spread over 3 continents and 12 countries sharing the same commitment for a better world.
