Our take
Nature-based assets are increasingly vital for decarbonising the economy, as they are the most efficient means of removing carbon dioxide from the atmosphere. However, the lack of accessible, understandable, and trustworthy data hinders enterprises from investing in these assets at the necessary scale. This issue, along with regulatory changes like the EU Deforestation Regulation (EUDR) and the demand for supply chain transparency, is creating a positive tipping point that underscores the need for reliable nature-based data solutions.
Treefera is an AI-enabled data fabric platform that enhances transparency and accuracy in nature-based asset reporting. It provides 360-degree visibility into the first leg of commodity supply chains by integrating satellite, drone, and ground truth data via advanced AI algorithms. Working across commodities and carbon capture, it collates and organises large data sets into actionable, risk-mitigating insights. Treefera provides essential data products and workflows for continuous monitoring, assurance, and risk evaluation at a fraction of the computing power used in other AI tools and makes previously unseen information concerning real-world assets transparent, usable and defensible.
Serving a diverse clientele, including project developers, biochar producers, carbon credit market players, and bioenergy companies, Treefera covers jurisdictions across multiple regions and over 500 registered forest projects and harvest sites. The platform consolidates extensive environmental and forestry data and integrates with client analytics through an API, ensuring seamless access to critical information. As a global enterprise with operations in the US, UK, Europe, LATAM, and Asia, Treefera is committed to making the true power of nature-based solutions visible to all.
