Dan McIntyre‑Clark
Environmental, Health & Safety Manager
Browne Jacobson
Starting with the foundations of a GHG inventory and moving to SBTi target verification and ISO 14001 certification, Dan has covered a lot of ground in an impressively short amount of time. It is fantastic to hear that Dan has become a trusted sustainability advisor to colleagues and senior leadership within the firm owing to his collaborative approach.
LSA Co-Chairs:
Becky Clissmann, Global Sustainability Expertise Counsel, Ashurst Perkins Coie
Paddy Linighan, Chief Sustainability Officer, Clyde & Co LLP
Dan has demonstrated exceptional leadership in turning climate ambition into credible, measurable progress since joining the firm in 2022. In just four years, he has established a comprehensive greenhouse gas inventory covering Scopes 1, 2 and 3, strengthened emissions management and built the foundations for long-term decarbonisation. This work enabled an independently assessed baseline and the submission and subsequent approval of science-based Near-Term and Net Zero targets by the SBTi, a milestone first discussed in November 2023, formally committed to in February 2024, submitted in February 2026 and now successfully achieved.
His impact is demonstrated through significant measurable achievements. Dan led the firm to ISO 14001 certification with zero non-conformances across all UK and Ireland offices, delivered three CCS-verified Carbon Reduction Plans, and helped increase its EcoVadis environmental score from 40 to 82 in just three years. He has also driven strong colleague engagement, achieving 80% participation in the firm’s commuting survey.
Dan combines technical expertise with creativity and an ability to bring people with him. He established the Sustainability Steering Group and Green Network, developed community and supply-chain partnerships, and has led successful firm-wide World Environment Day initiatives. His 2026 #WED100 campaign generated 163 volunteering hours across six offices, involving 71 participants.
What sets Dan apart is his humility and collaborative approach. He consistently gives credit to others, builds engagement and creates a culture in which sustainability is collectively owned rather than the responsibility of one team. He has been a trusted and constructive voice for colleagues and senior leadership alike.
Through robust data, strong governance, measurable results and authentic leadership, Dan has transformed sustainability from an aspiration into an organisation-wide priority and positioned the firm for meaningful, long-term environmental change.
