Investors in the Environment (iiE)

What Investors in the Environment (iiE) does

Investors in the Environment (iiE) is a UK not-for-profit national sustainability accreditation scheme established in 2010 and wholly owned by the environmental charity Peterborough Environment City Trust (PECT). Headquartered in Peterborough with a regional presence in Newcastle, iiE operates a three-tier progressive accreditation framework (Bronze, Silver, Green) that guides organisations through structured Environmental Management System development, from baseline implementation to net zero preparation. The framework is delivered through an environmental management system platform, supported by a Smart Carbon Dashboard (built on the Greenhouse Gas Protocol with UK Government and IEA conversion factors for SECR compliance), the Stickerbook gamified microlearning platform, and a suite of accredited training courses including ISEP Pathways to Net Zero, ISEP Foundation Certificate, iiE Green Champion, and Carbon Literacy Training delivered with Change Agents UK.

iiE serves a horizontally segmented UK customer base spanning SMEs, large multi-site organisations, and local authorities/public sector bodies across veterinary, legal, education, healthcare, government, charity, retail, professional services, and leisure sectors. Hundreds of member organisations collectively represent over 40,000 employees. Revenue is generated through annual recurring membership subscriptions (Basic from £999/year, with Advanced and Enterprise tiers quoted on application), one-time training course fees (member discounts of 10-25%), and consultancy services bundled into Advanced and Enterprise plans. Distribution combines self-serve online registration for SME tiers, direct enterprise sales with a 48-hour response commitment, and a licensed hub partner model (e.g., Genee in North England) intended for international expansion.

The commercial model is augmented by an ecosystem of partnerships including PECT (parent charity), ISEP (accredited training), Good Business Charter, Vet Sustain, Croner, Ecotricity, Forest Carbon, Climate Ambassadors, and Change Agents UK. Marketing is event-led (annual iiE Conference and Awards), supported by content marketing, partner referrals, and digital channels. No external funding has been raised; the organisation is funded through membership and training fees with proceeds supporting PECT's charitable mission.

Expansion highlights5 records

Broad incumbents

• EcoVadis: Global sustainability ratings platform used by large enterprises to assess supplier ESG performance. Comparable to iiE in that both enable organisations to evidence sustainability credentials, but EcoVadis operates at much larger scale, serves multinational supply chains, and is technology-led rather than advisor-led.
• CDP (Carbon Disclosure Project): Global non-profit running the leading carbon and environmental disclosure system used by corporates, investors, and cities. Comparable to iiE as a sustainability disclosure/credentialing body, but CDP focuses on disclosure and benchmarking for large corporates and capital markets rather than SME accreditation.
• The Carbon Trust: Established UK-based organisation providing carbon certification, advisory, and standards work. Comparable to iiE in that both operate in UK sustainability certification and advisory, though the Carbon Trust is much larger and serves a broader enterprise and government audience with deeper consultancy capabilities.
• B Lab (B Corp Certification): Operates the global B Corp certification for businesses covering social and environmental performance. Comparable to iiE as a recognised sustainability/responsible-business accreditation scheme, but with a much larger global brand, broader scope (social + environmental + governance), and higher name recognition among corporates.

Direct peers

• Achilles Information: Operates supplier accreditation and prequalification schemes (e.g., Achilles Verify, BREEAM-aligned programmes). Comparable to iiE in that both run membership-style accreditation with tiered certification and audit-based evidence, primarily serving UK and European buyers.
• Planet Mark: UK-based sustainability certification scheme offering annual accreditation and carbon footprint certification to businesses. Directly comparable to iiE in that it sells a recurring membership-style certification tied to carbon measurement and ESG progress, targeting similar UK SME and corporate buyers.
• Vet Sustain: UK veterinary-sector sustainability organisation that supports vet practices with sustainability tools and training. Directly comparable as a vertical-specific sustainability accreditation and tooling partner that co-develops content with iiE and refers veterinary practices into the iiE scheme.
• Good Business Charter: UK accreditation for responsible business covering ten components including environment. Comparable to iiE as a UK not-for-profit membership accreditation scheme, and explicitly partners with iiE via cross-referral (GBC waives fees for iiE members).

Emerging players

• Net Zero Now: UK-based certification scheme focused specifically on credible net zero accreditation for SMEs and corporates. Directly comparable to iiE's higher tiers and Smart Carbon offering, competing for similar UK SME net-zero accreditation budgets.
• SME Climate Hub: Global initiative helping small businesses commit to and act on climate. Comparable to iiE's SME-focused accreditation and net zero framework as an entry-level sustainability commitment and action pathway, though delivered as a free commitment rather than paid accreditation.
