How Clarke Willmott gained complete emissions visibility and reduced Scope 1 and 2 emissions by over 90%
Who is Clarke Willmott?
Clarke Willmott LLP is a national law firm with more than 700 lawyers and support professionals, including over 125 partners, across offices in Birmingham, Bristol, Cardiff, London, Manchester, Southampton and Taunton. Established in the South West in 1888, the firm provides legal services across a broad range of practice areas, including commercial property, real estate, family law and private client services.
The Challenge:
Like many professional services firms, Clarke Willmott had a broad understanding that the majority of its emissions were likely to sit within Scope 3, but lacked the detailed data needed to confirm where emissions were coming from or where to prioritise action.
The firm needed to establish a robust carbon baseline to better understand its emissions profile and identify the areas that would have the greatest impact on its decarbonisation journey.
The Goal:
Clarke Willmott was looking for more than a carbon accounting platform. It wanted a trusted climate transition partner with the expertise to navigate evolving regulations, provide strategic guidance and help the business achieve its net zero ambitions.
The firm needed a partner that could simplify complex sustainability requirements while providing practical recommendations tailored to a professional services organisation.
The Solution:
The team worked closely with Clarke Willmott to establish a comprehensive emissions baseline and develop a clear roadmap for reducing emissions.
Beyond the platform, the 51toCarbonZero team became an extension of Clarke Willmott’s ESG function—providing expert guidance, responding quickly to questions and proactively keeping the team informed of changes in climate policy and reporting requirements ahead of compliance deadlines.
With experience supporting professional services firms, 51toCarbonZero understood the unique challenges Clarke Willmott faced and provided practical, industry-specific advice throughout its climate transition.
“The value of 51toCarbonZero is that they really are an extension of your team. We have more minds on the job, and they are incredibly flexible and innovative in helping us understand our decarbonisation journey and make it easier and more engaging for the rest of the company.”
