What Greengage | B Corp™ does

Greengage Solutions Limited is a UK-headquartered sustainability certification and consultancy founded in 2020, focused exclusively on the travel, hospitality, and events sectors. The company is structured around three integrated product lines: ECOsmart, a third-party-verified sustainability certification scheme covering accommodation, venues, and event agencies; the CO2 Toolkit (paired with the IMPACTportal), which provides carbon measurement and reporting functionality; and 360 Consulting, an advisory service built on the founder's 20+ years of travel industry experience and a leadership team drawn from TUI, Carnival, dnata Travel, and Visio. The platform is aligned to recognized external frameworks including UN Sustainable Development Goals, GSTC Industry Criteria, ISO 14001, and emerging CSRD requirements, and the company itself holds B Corp certification (2024).

The technology layer consists of the CO2 Toolkit, IMPACTportal data aggregation, the ECOmap directory of 400+ certified suppliers, and SMARTscan AI (launched 2025), which applies AI-assisted review and anomaly detection to the certification assessment workflow. Partnerships with Replacer (sustainable supplier recommendations), Zedible (food/hospitality decarbonization), and Carbon Footprint extend the platform into adjacent workflows, and an Impact Reports feature (launched April 2026) standardizes disclosure outputs. The certified network spans the UK, continental Europe, the USA, Asia (including Singapore), Australia, and the Middle East (Ras Al Khaimah).

Greengage's revenue model combines recurring certification subscriptions, enterprise and venue-level consultancy engagements, and standardized training (priced at approximately £350 per person). Go-to-market is B2B and operates through direct sales to hotels, venues, TMCs, and event agencies, supplemented by ecosystem partnerships and thought-leadership content (including the INSIGHTS Podcast, launched November 2023). The company is privately held and bootstrapped, with no disclosed external funding, and operates with a headcount of approximately 25 employees from its Taplow, UK base.

Direct peers

• Thrust Carbon: Thrust Carbon is a carbon-measurement and reporting platform built for the business travel and events industry — directly comparable to Greengage's IMPACTportal/CO2 Toolkit offering for TMCs, venues and event agencies.
• Green Key: Green Key is an internationally recognised eco-label awarding certificate programmes to hotels, venues and event suppliers — directly competing with ECOsmart in the same hospitality/events sustainability certification niche across multiple regions.
• Travelife: Travelife provides sustainability certification and training specifically for hotels and accommodations in Europe and emerging markets, with comparable Bronze-to-Gold tiering, GSTC alignment, and a focus on independent verification — a direct competitor to ECOsmart.

Broad incumbents

• B Lab: B Lab administers the global B Corp certification that Greengage itself holds; it is a comparable sustainability/credibility certification body that addresses similar buyer concerns around credible ESG credentials, albeit across all industries rather than hospitality-specifically.
• SGS: SGS is a worldwide inspection, verification, testing and certification company with sustainability services that span hotels, tourism and corporate ESG — overlapping with Greengage's certification, training and assurance offerings but as part of a much broader portfolio.
• Bureau Veritas: Bureau Veritas is a global testing, inspection and certification firm that offers sustainability, ESG and environmental certification services across industries, including hospitality — a much larger incumbent that overlaps with ECOsmart's certification remit.
• South Pole: South Pole is a large climate-solutions provider offering carbon accounting, offsetting and advisory services — comparable to Greengage's carbon measurement and consultancy offerings, particularly via partnerships with Carbon Footprint, but with a much broader enterprise focus.

Emerging players

• Watershed: Watershed is an enterprise carbon-accounting and sustainability-reporting platform — comparable to Greengage's CO2 Toolkit/IMPACTportal functionality but oriented toward larger corporates rather than travel/hospitality specialists.
• Replacer: Replacer is a sustainability platform helping hospitality and event venues source sustainable products and suppliers, and is integrated directly into the ECOsmart platform — a partner-and-adjacent peer with overlapping venue-sustainability functionality.
