What Trees4Travel does

Trees4Travel Limited is a UK-based environmental 'Tech For Good' company founded in 2020 and operating as a subsidiary of ZEERO GROUP (company registration no. 12434435). Its core product is a carbon management platform for the travel industry that calculates emissions for trips and events using a methodology stack combining DEFRA, GHG Protocols, HCMI, Greenview, Google TIM, and Cirium standards, then visualises impact through traveller, travel-advisor, and corporate dashboards. Distribution is multi-channel: direct self-serve at my.trees4travel.com, API and booking-system integrations for OTAs, hotels, and travel management companies, and a partner program with white-label options.

The company monetises through three streams: per-trip and per-booking climate contributions (suggested €2–€5 per booking) that fund tree planting via the Eden Reforestation Projects partnership across Madagascar, Kenya, Mozambique, Haiti, and Nepal, with each tree backed by a UN renewable energy carbon credit; subscription programs for regular travellers; and licensing of its carbon-measurement technology via APIs and white-label integration into enterprise partner platforms. Hybrid Climate Contribution Packages combine reforestation with renewable energy investments under two SKUs (UN Hybrid CC and ZEERO Hybrid CC). Cumulative reported impact includes 1.75 million trees planted and 252,878 tons of emissions reduced.

Trees4Travel sits within a broader ZEERO GROUP portfolio that includes ZEERO 360 (corporate carbon accounting and reporting), ZEERO Events (carbon management for the MICE industry, integrated into the Cvent App Marketplace as v2.0, formerly Trees4Events), and ZEERO Energies (renewable energy including Hydrothermal Liquefaction waste-to-biofuel technology claimed to deliver at least 81% lower emissions than fossil fuels for aviation, marine, rail, road, and generator applications). The customer base spans enterprise logos such as Flight Centre, Avalon, SilverDoor, Uniglobe, National Grid, Cvent, Agiito, and ETOA, with industry association memberships in IATA (Strategic Partnerships Program from April 2025), GBTA, GSTC, USTOA, ATAS, ETOA, and the Sustainable Hospitality Alliance.

Direct peers

• Lune: Lune provides an API and dashboard for businesses — including travel brands — to embed carbon offsetting at checkout. It is a direct competitor in the per-booking climate contribution space Trees4Travel targets.
• Chooose: Chooose is a climate engagement platform that enables travel, aviation, and mobility companies to integrate carbon calculations and offsetting at checkout — directly overlapping Trees4Travel's per-booking climate contribution model.
• Patch: Patch provides carbon credit APIs for embedding offsetting into digital products including travel booking flows. It is the closest direct competitor to Trees4Travel's API-first carbon management offering for travel brands and OTAs.
• Cloverly: Cloverly offers a carbon offsetting API used by travel and logistics companies to calculate and offset emissions at point of sale. It competes head-to-head with Trees4Travel on enterprise API integration and embeddable climate contributions.
• CarbonClick: CarbonClick offers a simple, one-click carbon offset solution for e-commerce and travel sites, similar to Trees4Travel's €2-€5 per booking model. Both target consumer-facing and SME travel brands for point-of-sale climate contributions.

Emerging players

• Persefoni: Persefoni is a climate management and accounting platform for enterprises, focused on financial-grade carbon accounting. It is comparable to ZEERO 360's measurement and reporting tools for corporate travel buyers.
• Watershed: Watershed is an enterprise carbon accounting and reporting platform used by corporates for ESG and Scope 3 reporting. It overlaps with ZEERO 360's corporate measurement, accounting and dashboard functionality.

Others

• Cvent: Cvent is the dominant meetings and events management platform and a Trees4Travel distribution partner through the Cvent App Marketplace. It is an ecosystem enabler rather than direct competitor, but its strategic importance to ZEERO Events' GTM is high.

Broad incumbents

• ClimatePartner: ClimatePartner is a larger, established carbon offset and climate action consultancy serving many industries including travel. It is a broad incumbent competing with Trees4Travel on enterprise carbon management programs and offset procurement.
• South Pole: South Pole is a major carbon project developer and advisory serving corporates across sectors including travel and aviation. As a broad incumbent, it overlaps with ZEERO Energies' project development work and Trees4Travel's corporate advisory offerings.
