Tree-Nation credentials

Mission & impact

Tree-Nation was founded in 2006 with a dual purpose: to reforest the planet and combat climate change by sequestering carbon. We have an ambitious mission to plant one trillion trees by 2050, and are working with urgency to reach it. Boasting over 20 years of dedicated experience, we have already nurtured the growth of more than 45 million trees, and we're just getting started.

Sponsor base

Tree-Nation directs the funds of 20,000+ corporate sponsors to planting projects across the six continents. Sponsors enjoy a comprehensive suite of services, including personalized forests, certified trees, impact tracking, frequent project updates, and communication tools to amplify their planting activities.

Our projects

Tree-Nation holds over 40 reforestation projects across more than 20 countries. These projects vary in ecosystem, species selection, and planting techniques. Certified projects are organized under our four certification pathways (Foundation, Mission, Nature, and Forest Gardens), with projects not yet transitioned to one of these pathways categorized as Legacy. All projects are evaluated and monitored under Tree-Nation’s Environmental Certification Methodology.

Environmental certification

Tree-Nation applies its Environmental Certification Methodology to validate, verify, and monitor each reforestation project. This methodology defines the framework applied across all four certification pathways (Foundation, Mission, Nature, and Forest Gardens), covering legal validation, environmental validation, activity validation, and the full Monitoring, Reporting, and Verification (MRV) chain. The methodology provides a consistent and transparent standard for assessing biodiversity restoration, carbon capture, and long-term project outcomes.

Carbon Calculation Methodology

Tree-Nation’s Carbon Calculation Methodology defines the per-tree carbon math applied to every project, including the ex-ante calculation based on species biology, survival rate adjustments, cull-back and prudence reductions, and a 10-year crediting cap. Conservatism is built directly into the calculation rather than through a shared buffer pool, keeping each project’s carbon claim defensible on its own evidence.

Project validation & verification

We maintain the quality and integrity of our projects through a structured verification system. Project holders provide standardized project data that Tree-Nation evaluates to assess environmental impact and long-term viability. Verification relies primarily on remote evidence (satellite data and geolocated photographs), with periodic on-site visits where direct field confirmation adds value. All verification layers are consolidated annually into the Tree-Nation Verification Quality Score (VQS). Projects must adhere to our environmental and social criteria and continue to provide updated data to sustain their VQS.

Independent 3rd-party verification

In addition to project reporting and on-site audits, Tree-Nation uses independent third-party satellite datasets to verify the environmental performance of certified projects. These external measurements allow Tree-Nation to monitor vegetation development and assess project outcomes over time, providing an additional layer of verification alongside field monitoring and project documentation. Foundation and Mission projects additionally receive an independent third-party assurance audit at Year 5 of their crediting period.

Partnerships

Tree-Nation is an active participant in the United Nations Environment Programme (UNEP) initiatives, and our operations are guided by fourteen of its seventeen Sustainable Development Goals. Since 2024, Tree-Nation has also been an official partner of the UNCCD to combat desertification.

Transparency

Tree-Nation provides extensive information about each planted tree via a unique URL which tracks its status, species, associated project, and downloadable certificate. Our projects are described in detail within their dedicated spaces, which showcase their planting sites and respective geolocations, the complete list of species planted therein, and offer a space for sponsors to leave reviews of their individual experiences.

Corporate governance

Tree-Nation operates according to a formal Code of Conduct that sets the ethical, legal, and professional standards governing our business. It covers integrity and anti-corruption, responsible environmental communication, human rights, data protection, fair competition, and whistleblowing protections — among other areas. This document applies to all employees, directors, contractors, and representatives. Download our Code of Conduct (PDF)

Operating Structure

Tree-Nation operates as a private company, leveraging this structure to effectively achieve our mission and professionally meet the needs of our sponsors. While we have previously operated as a non-profit for several years, we believe the private company model provides the best framework to fulfill our mission and maintain operational excellence.

Risk management

Tree-Nation addresses the risks that affect reforestation outcomes through several complementary mechanisms. Planter contracts include minimum survival rate commitments and require project implementers to replant trees that fail to meet these thresholds during the agreed maintenance period. Carbon claims are kept conservative through the structural under-crediting built into the Carbon Calculation Methodology, so that typical variance in survival and site performance is absorbed within the credited figure itself.
