CTrees contributes data to Climate TRACE emissions inventory

When former vice president Al Gore took the stage at COP27 this week to present the latest global greenhouse gas emissions data from the nonprofit coalition Climate TRACE, he relied on CTrees for information on emissions from forestry and land use. 

Climate TRACE’s update to its global inventory provides the most complete view available of emissions by country and sector.

CTrees provided data on carbon stock, emissions, and removals for forests and other land cover types, including wetlands, shrublands, and mangroves, globally from 2015 to present.  Forestry and land use is the 8th leading sector for global emissions, according to Climate TRACE. In 2021 alone, the sector accounted for 12.6 billion tons of carbon dioxide equivalent emissions. CTrees’ data covers three subsectors: forest and mangroves; grasslands and shrublands; and wetlands. 

The measurements were generated in CTrees’ data platform, which applies peer-reviewed science and state-of-the-art technology to measure changes in forest carbon at all scales. Using cloud-based computing and artificial intelligence, CTrees integrates advanced satellite technology (lidar, radar, optical imagery), science-based algorithms, and inventory plot data to accurately map variations of carbon stored in forest and non-forest landscapes.

CTrees is one of more than 90 organizations contributing to the Climate TRACE data initiative, which strives to make emissions information freely available and inform how leaders prioritize emissions cuts. 

Emissions inventories will be especially important this year as countries tally their emissions as part of the global stocktake, a UNFCCC effort to track progress against the Paris Agreement’s goals. 52 countries have not submitted any emissions inventories covering the last ten years, and those that have submitted often contain emissions or lack sufficient detail to inform decisionmaking. 

Anyone on the Climate TRACE website can view forestry and land use emissions for every country globally and compare emissions from forestry and land use to emissions from other sectors, like power, manufacturing, and agriculture. CTrees’ forestry and land use data and our underlying methodology are available for download.
