TUNLEY ENVIRONMENTAL'S TIMELINE

The Tunley name has its roots in engineering. Dr William Beer's great-grandfather, Frank Tunley, worked as a pattern maker for Laycock Engineering in Sheffield from the 1920s to the 1960s. 

Generations later, a shared interest in engineering, design and environmental improvement inspired the creation of Tunley Engineering. What began as a business focused on improving engineering processes has since evolved into Tunley Environmental - a science-based sustainability consultancy supporting organizations across carbon, nature, water and regulatory compliance. 

  • 2016: The idea begins

    The early concept for what would become Tunley Environmental began in 2016. Dr William Beer recognized how improvement to engineering processes could create lasting operational change, laying the foundations for the business that followed.

  • 2017: Tunley Engineering is established

    Tunley Engineering became a registered company, with William Beer committing fully to growing the business. Initially focused on helping organizations improve engineering processes and lead times, Tunley also secured its first customer during the year.

  • 2018: Going global

    Tunley secured its first global contract and adopted a cloud-based Business Management System. The company also achieved ISO 9001:2015 certification, demonstrating its commitment to quality management as the business continued to grow. 

  • 2019: Expanding Tunley's expertise

    Following continued growth, Tinley expanded its offering to include training solutions for engineers, building on the experience gained through its engineering assessments and clients work. 

  • 2020: Adapting through change

    As COVID-19 changed the way organisations operated, Tunley's existing remote working model enabled the team to continue supporting clients without relying on on-site delivery. 

  • 2021: A greater focus on decarbonization

    Tunley launched 'Engineering a Decarbonized Future', bringing together a team of carbon specialists and marking a significant expansion into supporting organizations with understanding and reducing their carbon emissions.

  • 2022: Growing environmental services

    Demand continued to grow for Tunley's environmental work, including Embodied Carbon Assessments, alongside an increase in recurring client partnerships.

  • 2023: Tunley Environmental is born

    Tunley Engineering became Tunley Environmental, reflecting the company's evolution beyond engineering and carbon into wider environmental sustainability. 

    The team expanded its expertise into biodiversity, introducing new services to support organizations in understanding their impact on nature and responding to emerging Biodiversity Net Gain requirements. 

  • 2024: Expanding our environmental expertise

    Tunley continued to broaden its environmental services, introducing support across areas including water footprinting, supply chain biodiversity, Environmental Product Declarations and CBAM support. The company also became certified to support organizations with Airport Carbon Accreditation and partnered with training provider Astutis to deliver specialist sustainability and carbon accounting training. 

    The year also marked the beginning of Tunley's international team, with our first team member based in Mauritius. By 2026, this had grown to a team of four. 

    Tunley's also launched its Sustainability Verification Badge, giving organizations completing eligible assessments with Tunley a way to demonstrate their commitment to credible environmental action. 

    Recognition: Dr William Beer was named a finalist for CEO of the Year at TheBusinessDesk.com Yorkshire Leadership Awards, while Tunley Environmental was recognized as Best Sustainability Consultancy 2024 at the Northern Enterprise Awards. 

  • 2025: Broadening our sustainability offering

    Tunley continued its evolution into a multidisciplinary environmental sustainability consultancy, expanding its services across carbon, nature, circularity and regulatory reporting. New areas of support included CSRD and Double Materiality Assessments, Sustainable Procurement aligned with ISO 20400, SBTi alignment, Circular Economy Assessments and a wider range of nature and biodiversity services. 

    The year also saw Tunley reorganize its offering around the environmental challenges organizations face, introducing its 'What We Do' and 'Our Expertise' structure and launching dedicated sector pages to make it easier for organizations to find support relevant to their industry. 

    Tunley also moved into publishing with the launch of its first book, 99 Facts of Climate, Science and Society, using AI-generated imagery to illustrate the impact behind the facts. Dr William Beer and Dr Tara Garraty also continued as featured authors to The Customer is The Planet.

    Recognition: Tunley ranked #18 in Elite Business's Top 100 SME Businesses 2025, was named Net Zero Champion 2025 at the Good Small Business Awards. Dr William Beer also received Sustainability Entrepreneur of the Year - North East, Yorkshire and Humber.

  • 2026: From specialist support to sustainability technology

    Tunley continued to expand its specialist support in 2026, introducing new services across climate risk and resilience, nature regulation, BREEAM, Extended Producer Responsibility and PAS 2090, alongside a new retainer model designed to provide organizations with ongoing access to Tunley's environmental expertise. 

    The launch of the Tunley Impact Network also strengthened our approach to external partnerships, while a growing collection of client case studies began showcasing the progress being made through longer-term relationships. 

    Sharing our expertise

    Early in 2026, Tunley published The Sustainability Leader's Playbook 101, continuing the company's work to make sustainability knowledge more accessible to business leader's and sustainability professionals.

    Launching VerdaMetric

    Later in 2026, Tunley Environmental launched VerdaMetric, its sustainability management software, marking a new chapter in the company's development. 

    Built around the challenges our scientists encounter when supporting organizations with carbon accounting, reporting and sustainability management. VerdaMetric brings sustainability data, calculations, evidence, performance monitoring, reduction planning and supplier engagement into one platform. 

    The launch brings together Tunley's science-based consultancy expertise with technology designed to support organizations with the ongoing management of environmental sustainability. 

    Recognition: Tunley's work was recognized at the International CSR Excellence Awards, while Dr William Beer received the Green Leader award at the North West Leadership Awards.
