ReTree

What ReTree does

ReTree is a Madrid-based reforestation and carbon offsetting platform founded in 2018 that targets large enterprises with ESG mandates, CSRD reporting obligations, and carbon neutrality goals. The company converts degraded land into measurable, certifiable carbon sinks using native species selected for climate resilience through 2050–2080 projections, executing projects across decentralized forests in Spain and Portugal. Its core product is CARBIN, a proprietary software platform that combines multispectral satellite data from NASA, ESA, and JAXA with AI, biophysical models, climate variables, and blockchain to deliver real-time CO2 capture measurement and ESG indicator tracking across 100% of project surfaces, with independent verification by EY (operational) and UCAV (scientific). ReTree manages the official MITECO "Calculo, Reduzco, Compenso" carbon offset certification seals on behalf of clients, positioning the company within the regulated Spanish carbon registry framework.

The company operates a vertically integrated model spanning land identification and acquisition, reforestation execution, long-term plantation maintenance, ongoing monitoring, and certification management. Its revenue model combines subscription-based carbon offset programs and CARBIN platform access with transaction fees on generated carbon credits and professional services for corporate reforestation days and gamified sustainability team-building events. The enterprise go-to-market is consultative and direct, beginning with carbon footprint calculation and tailored action plan design and extending through multi-year contracts that bundle reforestation, MITECO certification, and ongoing ESG reporting via APIs, iframes, or custom landing pages. The customer base of 40+ enterprise logos spans hospitality (NH Hotel Group, TRH Hoteles), energy (Sonnedix), banking (Banco Santander, AllianceBernstein), beverages (Mahou, Pernod), healthcare (Sanitas, Abbott), pharmaceuticals (Rovi, Cofares), industrial (ArcelorMittal, Prosegur), retail (Decathlon, Ecoembes), and engineering (AECOM).

ReTree is a privately held Spanish SL (RETREE&SPACE SOLUTIONS, S.L.) with no disclosed external funding, no parent company, and approximately 20 employees organized across R&D, field operations, IT, forest generation, marketing, and finance. The leadership team is headed by CEO Pablo Esteve and Founder Pedro Pérez de Ayala. While the company has achieved meaningful enterprise penetration and a defensible technology and verification stack, geographic operations remain confined to Spain and Portugal, and the absence of disclosed revenue, funding, or ARR limits visibility into scale and growth velocity.

Core offering

ReTree regenerates degraded lands into measurable and certifiable carbon sinks by reforesting with native species adapted to future climate conditions across Spain and Portugal. The company provides carbon offsetting services, MITECO certification management, reforestation team-building events, and a proprietary CARBIN software platform that delivers real-time, satellite-driven CO2 and ESG measurement with double independent verification (operational by EY and scientific by UCAV).

Product overview

Retree is a triple-impact reforestation platform that combines a proprietary technology stack — centered on the CARBIN measurement software — with a suite of service offerings including carbon offsetting, reforestation days, sustainable team-building, and MITECO certification management. CARBIN enables real-time, satellite-driven CO₂ and ESG measurement across all project surfaces, delivering data via API, iframes, or customizable landing pages for client reporting and stakeholder communication. The broader service portfolio encompasses land selection, native-species reforestation, biodiversity corridors, and post-fire restoration, all supported by R&D+i capabilities in carbon absorption modelling, fire-risk prediction, and biodiversity conservation.

Broad incumbents

• Climate Impact X: CIX is a global carbon credit exchange and marketplace backed by DBS, Standard Chartered, SGX, and Goldman Sachs. It competes with ReTree for institutional carbon credit buyers and offers standardized high-quality nature-based credits at scale.
• Verra: Verra operates the Verified Carbon Standard, the world's largest voluntary carbon credit standard, and is integral to credit issuance for forestry projects. ReTree's projects would interact with Verra registries, and Verra's standards directly shape ReTree's credit marketability.
• South Pole: South Pole is a large global carbon credit developer and ESG consultancy offering nature-based solutions, renewable energy credits, and advisory services to enterprises. It is a broader incumbent that competes with ReTree across carbon credit sales and sustainability advisory in Europe.
• EcoAct: EcoAct is an international carbon consultancy and project developer serving enterprises with carbon strategy, offset procurement, and net-zero advisory. It overlaps with ReTree's enterprise GTM motion and CSRD/EU Taxonomy positioning, but operates as a broader consultancy rather than a project developer.

Direct peers

• Tree-Nation: Tree-Nation is a reforestation platform that enables companies and individuals to plant trees and offset carbon via certified projects worldwide. It overlaps with ReTree's reforestation-as-a-service offering and corporate team-building events, though with less proprietary MRV technology.
• Sylvera: Sylvera provides independent ratings and MRV for carbon credits using satellite data and machine learning, helping enterprises evaluate credit quality. It directly overlaps with ReTree's CARBIN verification approach and competes for the same enterprise ESG procurement budget.
• Pachama: Pachama is a leading AI-powered carbon credit marketplace and MRV platform connecting companies to verified reforestation and nature-based projects globally. Like ReTree, Pachama combines satellite imagery and ML for forest carbon measurement, but operates at much larger scale and serves global enterprise customers.

Emerging players

• Cloverly: Cloverly is a carbon offset API and sustainability platform offering both carbon credit purchasing and embedded sustainability tooling for enterprises. Like ReTree, it emphasizes API-driven integration with enterprise ESG reporting workflows.
• Patch: Patch provides a carbon offset API enabling developers to embed carbon credit purchases directly into apps and platforms. It overlaps with ReTree's CARBIN API strategy but is more developer-focused and operates globally with a marketplace model rather than project development.

Regional players

• Bosques Amazónicos (BAM): BAM is a Latin American nature-based solutions developer focused on Amazon reforestation, but operates in a different geography than ReTree. It illustrates a comparable project-development model that combines forest restoration with carbon credit generation and community impact.
