What Tunley Environmental does

Tunley Environmental is a privately held, science-led environmental sustainability consultancy founded in 2017 and headquartered in Wakefield, United Kingdom, with an additional US presence. The firm delivers carbon, nature/biodiversity, water, climate risk, and product/project sustainability services — including carbon footprinting across Scopes 1-3, Life Cycle Assessments (LCA), Environmental Product Declarations (EPD), Biodiversity Net Gain assessments, Supply Chain Biodiversity Footprint (SCBF) analyses, water footprinting, and CSRD/CBAM/SECR regulatory compliance — through a team dominated by PhD-level scientists.

The company operates a consultative, sales-led go-to-market with both inside-sales coverage in the UK (+44) and US (+1), supported by content marketing, free downloadable guides, webinars, whitepapers, and a service-discovery quiz.

Customers span manufacturing, pharmaceuticals and medical devices, construction, mining/metals/steel, airports, ports and maritime, transport and logistics, chemicals/coatings/cleaning, architects and developers, and public-sector/education clients (e.g., University Hospitals Birmingham NHS Trust, Leicester College).

Emerging players

• Greenly: Greenly is a SaaS carbon accounting and climate management platform that has expanded into consulting-adjacent services such as CSRD readiness and net-zero advisory. It represents the tech-enabled, productised model that could disrupt or complement Tunley's bespoke consulting approach.

Direct peers

• Ricardo plc: Ricardo is a UK-listed sustainability and engineering consultancy offering carbon management, life cycle assessment and environmental compliance services. Its sustainability practice competes directly with Tunley on LCA, EPD and carbon strategy engagements.
• Anthesis Group: Anthesis is the largest pure-play sustainability consultancy globally and offers carbon footprinting, LCA, nature and supply-chain services to the same enterprise buyer segments (manufacturing, pharma, CPG) as Tunley. It is the closest scale-and-scope analogue to Tunley's science-based sustainability offerings.
• Carbon Trust: Carbon Trust provides carbon footprinting, net zero strategy, and supply chain sustainability advisory to UK and international organisations, including SMEs and large corporates. Its mission-aligned mandate and UK origin put it in direct competition with Tunley for UK enterprise and manufacturing clients.
• South Pole: South Pole is a global climate solutions provider offering carbon footprinting, target setting, nature-based solutions and sustainability advisory. It serves the same enterprise buyer set and overlaps on carbon, scope 3 and nature services, including supply chain engagement.
• SLR Consulting: SLR Consulting is an environmental and sustainability consultancy with deep UK presence, offering carbon, EIA, biodiversity and ESG advisory to industrial, mining, infrastructure and built environment clients. It overlaps materially with Tunley's sectors-and-services matrix.
• Avieco: Avieco is a UK-based sustainability consultancy delivering carbon footprinting, supply chain sustainability, LCA and ESG advisory to enterprise clients. As a similarly-sized UK specialist, it is one of the closest competitive analogues to Tunley.

It competes head-on with Tunley on CSRD, SBTi, TNFD and biodiversity engagements, but at much greater scale.

Broad incumbents

• RSK Group: RSK is a UK-based environmental services and engineering group offering carbon, EIA, biodiversity net gain and sustainability advisory among a wide portfolio. It overlaps with Tunley on BNG, carbon and construction-sector sustainability work but operates across a far broader environmental services value chain.
• WSP Environment & Sustainability: WSP is a global engineering professional services firm with a large environment and sustainability practice spanning carbon, biodiversity, climate risk and ESG advisory. It competes with Tunley across the same service lines but as part of a much broader infrastructure and built-environment portfolio.
