Who we are

We are scientists and engineers with over 20 years of experience in building global carbon monitoring systems and solutions that have informed climate change policies.

We have convened a group of leading experts, public and private partners to launch CTrees with philanthropic support. Our mission is to serve a larger community of project developers, investors, supplier countries, and decision makers with sustained and operational science-driven data.
