    IETA’s 2025 Greenhouse Gas Report has arrived at a pivotal moment for carbon markets. From the rise of Article 6 cooperation to breakthroughs in digital MRV, this year’s report highlights the innovations pushing markets forward and asks what it will take to unlock the next level of climate investment. The report, released this week, draws on the expertise of diverse contributors across policy, industry, finance, law, and digital innovation—including our own Sassan Saatchi, CTrees’ CEO and chief scientist. In his article, Saatchi discusses how the latest advances in satellite imagery and geospatial data are bringing unprecedented transparency and scale to nature-based solutions, especially those focused on trees and forests. Saatchi argues that innovations in earth observation and remote sensing have revolutionized the monitoring of nature-based solutions, with technologies like lidar, synthetic aperture radar (SAR), and hyperspectral imagery setting a new standard for credible carbon accounting and effective climate action.

    What’s on your data wishlist for jurisdictional REDD+? Jurisdictional REDD+ has the potential to deliver $4 billion in annual revenue to tropical forest jurisdictions by 2030 (EDF, 2024)—but achieving this impact requires the international community to commit financial, policy, and technology support to bring programs to scale. In a recent blog post, Raymond Song, CTrees’ carbon markets and policy lead, argues that a successful path forward demands honest conversations about past barriers to JREDD implementation, significant upfront capital, and access to reliable scientific data. To help scale JREDD, CTrees has developed a customizable data platform that jurisdictions or buyers can use to evaluate potential credits or monitor the performance of JREDD programs. The pillars of CTrees’ data system are: • Annual measurement of emission reductions • Near-real-time alerts • Monitoring of fire and reversal risks • Comparison between jurisdictions’ reported results and CTrees’ independent data Access the link to read the full article and learn more in the comment section below.

  • Tropical rainforests are home to more than half of global biodiversity and critical to the global carbon cycle—but they remain one of the least understood ecosystems on Earth. ORCHID, a new science initiative, seeks to change that. Introduced at #COP30, ORCHID would deliver the world’s most comprehensive tropical forest inventory by 2030, providing detailed carbon and biodiversity data on 1.5 billion hectares of tropical forest across the Amazon, Congo Basin, and Southeast Asia. The initiative would revolutionize how we monitor and protect these essential ecosystems. At the COP30 event organized by Sassan Saatchi, CTrees’ CEO and chief scientist, speakers from IPAM, the University of Sao Paulo, and the Science Panel for the Congo Basin discussed how an open-source reference dataset built in collaboration with local science institutions could address long-standing inequities in climate finance.

    Earlier this year, CTrees scientists released the most accurate and detailed canopy height assessment of the Amazon forest to date. Now, the peer-reviewed paper, led by CTrees scientist Fabien H Wagner, has officially been published in Remote Sensing in Ecology and Conservation. To develop the 5-meter spatial resolution map of the Amazon, researchers combined advanced deep learning models, airborne LiDAR data, and extensive satellite imagery. The result? The only open-access canopy height dataset that covers the entire Amazon and allows for identification of every canopy tree in the world’s largest rainforest. The data is available as cloud-optimized GEOTIFF files, with the option to download individual tiles or the entire dataset, through the Registry of Open Data on Amazon Web Services (AWS). Access the data, read the publication, and learn more through the links in the comments section below.

    The Amazon is losing its ability to capture and store carbon, according to an investigation published by Bloomberg this week. CTrees data was highlighted in the feature, which is part of a series on natural carbon sinks that are now faltering due to the effects of climate change. The map, based on CTrees data, shows the distribution of biomass carbon density across the Amazon rainforest in 2024. CTrees has tracked annual changes in biomass carbon in the Amazon basin and beyond for the last 25 years. The article also focuses on the latest investments and policy initiatives aimed at protecting and restoring the Amazon forest, a major theme of climate talks at #COP30 in Belém this week. CTrees is not only providing data to document threats to the Amazon—we are also working with government and private sector leaders to apply our scientific data to help raise finance, design policies, and implement programs that protect the world's most important carbon sinks.

  • At #COP30 this week, CTrees joined a new coalition of governments, Indigenous Peoples, investors, intermediaries, standard setters, and civil society to launch the Scaling J-REDD+ Coalition, a collective effort to accelerate action and finance for forests at the scale needed to meet global climate goals. Jurisdictional REDD+ is a forest finance mechanism that has potential to mobilize $3-6 billion per year by 2030 for jurisdictions taking action to reduce emissions from deforestation and forest degradation. Members of the coalition are working to build a stable market for high-integrity jurisdictional carbon credits. Its members have already helped establish enabling policies, mobilize early finance, and pioneer transactions that demonstrate both integrity and scalability. CTrees provides jurisdictions and buyers with accessible data and technology to evaluate potential credits and monitor the performance of JREDD programs. The four pillars of CTrees' JREDD data system are: 📊 Annual measurement of emission reductions 🛰️ Near-real-time radar alerts 🔥 Monitoring of fire and reversal risks 📚 Comparison between jurisdictions’ reported results and CTrees’ independent data Learn more about the Coalition and CTrees' offering in the comments. CTrees' JREDD team includes scientists, data engineers, and policy experts: Sassan Saatchi, Adugna Mullissa, Ricardo Dalagnol da Silva, Aleena Ashary, Ricardo Dalagnol da Silva, Raymond Song, Aleena Ashary, Daniel M., Janet Smith

    • We're proud to have joined the Scaling Jurisdictional REDD Coalition at COP30, a growing group of countries and organizations committed to accelerating the transition to a forest positive economy through high-integrity jurisdictional carbon credits. The scaling JREDD Coalition will take action to help JREDD mobilize 3 to 6 billion dollars per year for forest countries by 2030.

  • Legacy systems for monitoring and reporting U.S. forest carbon are outdated and inflexible, failing to meet the complex needs of forest managers, policy planners, and communities across the country. In a new commentary for the journal One Earth, Christopher Woodall, CTrees’ director of US forest science and policy explains why existing forest MRV systems in the U.S. need a reboot, and how advances in technology have made a new data infrastructure possible—one that accounts for every tree. Woodall previously served as a scientist with the USDA Forest Service for more than 20 years, where he helped build the infrastructure for reporting U.S. forest carbon to the UNFCCC. But that accounting approach is now insufficient, he argues. “We’re trying to use a system built for static, national ledgers to manage a living and constantly changing ecosystem,” said Woodall, “and that’s why it’s buckling under the pressure.” Woodall envisions a new infrastructure that starts with individual trees. Implemented as a public-private system, similar to our GPS and weather networks, the tree-level data architecture would provide reliable, granular, and verifiable data for public agencies, industry, and communities to plan solutions in any landscape. “I knew the accounting approach would need to be rebooted once science and technology had a chance to mature,” Woodall said. “Ten years later, I think we’ve arrived at that point.”
