Climate Hero Winner 2026
Claire Rainsford
Head of Sustainability at Winston Taylor
Claire exemplifies the spirit of the LSA Climate Heroes Award through her sustained commitment to driving meaningful, measurable environmental change within her firm and across the wider legal profession.
She has embedded sustainability into the DNA of Winston Taylor, developing a comprehensive framework spanning carbon reduction, responsible procurement, circular resource management and cultural engagement. She led the firm’s commitment to the Climate Pledge for Net Zero by 2040, established science-based targets and introduced robust governance and third-party assured data processes to strengthen accountability. Her decarbonisation programme has translated complex emissions data into a clear, actionable multi-year plan, driving reductions through energy efficiency, renewable energy procurement and significantly reduced business travel, while embedding sustainability into supplier selection and the refurbishment of the London office at 5 New Street Square.
Claire has also transformed the firm’s sustainability culture. Through training, communications, volunteering and a network of sustainability champions across departments and seniority levels, she has made environmental responsibility a shared commitment rather than a specialist function.
Her influence extends well beyond her own organisation. Through active involvement with the LSA, Legal Charter 1.5 and the Sustainable Markets Initiative, she champions collaboration and collective action across the legal sector. She also supports lawyers, colleagues and clients in navigating ESG challenges, regulatory expectations and sustainable business transformation.
Claire’s leadership was recognised when Taylor Wessing (which began trading as Winston Taylor in June 2026) was named Lamp House’s overall Responsible Business Leader for 2025. Her achievement demonstrates how ambitious targets, rigorous measurement and genuine cultural change can combine to make a lasting contribution to climate action.
