“The biggest uncertainty we have in terms of atmospheric CO2 driving climate change is the balance between deforestation and subsequent regrowth. GEDI is helping us address that.”

Proud to launch our Forest Carbon data! Accurate, timely maps of aboveground forest carbon, structure & height, *globally*. 🌳🌲🌍

The goal? Help underpin global carbon markets to accelerate our transition to a sustainable economy.

Really beautiful data, too :)

🌲🔥Exciting Update! We've overlaid our preliminary 30-m res burned area detection results on the Above Ground Biomass (ABG) image for Canada, revealing insights into areas affected by wildfires. It's estimated that 17.7 million hectares of forest have been burned this year!

The biomass of every tree in Europe was mapped. That allows us to quantify the overlooked contribution of trees outside forests, such as in urban areas, to national carbon stocks. Maps and codes for download via the paper in Science Advances science.org/doi/10.1126/sc…
