At Retree, we regenerate ecosystems and revitalize rural territories through impactful reforestation grounded in science, technology, and social commitment. We transform degraded land into living, traceable carbon sinks, using native species adapted to climate change and restoring biodiversity in a lasting way. We don’t just plant trees — we regenerate soils, protect water resources, and create economic opportunities in areas affected by depopulation. Our model integrates technology to ensure precise measurement, traceability, and transparency. Through our own platform, we monitor in real time the tonnes of CO₂ captured, biodiversity evolution, water status, and other key indicators. This enables companies, organizations, and public institutions to offset their carbon footprint in a reliable way, aligned with European regulations, the green taxonomy, and ESG criteria. 🌱 Regenerative reforestation with environmental, climate, and social impact 📊 Real-time data and traceability for verifiable compensation 📍 Territorial regeneration and rural job creation 🛰️ Technology and science applied to climate action We work with committed companies, regions, and institutions to scale real solutions to the climate crisis.
