We count every tree,
Because every tree counts

A platform to track carbon in every
tree and forest on the planet.

Scientific Data
Measurable Impact

CTrees is the first global monitoring system to enable robust forest carbon accounting with methods and data that are transparent, accurate, and actionable.

Our science-driven data products support efforts to reduce carbon emissions from deforestation and degradation and restore forests at all scales. 

Standard information
at all levels

With our products organizations can bring data to the climate fight, accurately measuring, reporting and verifying (MRV) the carbon in every tree, everywhere.


CTrees tracks the loss and gain of individual trees globally to create more accurate activity data and carbon emissions and removals, both inside and outside forest stands.

Projects to Jurisdictions

CTrees measures carbon stocks in forests at fine spatial resolution and over time, allowing policymakers, project developers, and investors to identify opportunities and track progress.


CTrees tracks forest carbon and land use activities within national boundaries, providing accurate data for country-level reporting under the Paris Agreement.


By continuously monitoring emission reduction efforts around the world, CTrees provides a global perspective on Earth’s carbon balance and impacts of climate mitigation investments.
