CTrees

CTrees is a U.S.-based science and technology 501(c)(3) nonprofit organization that has developed the first global system to monitor, report, and verify (MRV) carbon stocks and land-use activities for every ecosystem on land. Founded in 2022, CTrees was created by scientists to bridge the gap between science and technology innovation and the data needs of policy and markets. Today, our trusted, independent data is used by leading governments and organizations to measure the impact of programs and projects worldwide.
