Peter Hill receives an Honorary Degree of Doctor of Literature at Royal Holloway’s Winter Graduation ceremony.
Peter Hill has been recognised by Royal Holloway, University of London, for his outstanding contribution to public service and his pivotal role in advancing international action on climate change.
The award was conferred during Royal Holloway’s Winter Graduation ceremony on 18 December 2025, where students from the Department of Politics, International Relations and Philosophy celebrated their academic achievements alongside this special recognition.
As CEO of COP26 and Director General of the COP26 Unit, Peter led the UK’s largest ever sustainability conference in Glasgow during the Covid pandemic. Under his leadership, COP26 achieved historic progress, including the first global agreement to phase down coal power and a renewed focus on the relationship between nature and climate.
Peter’s 25-year career in the civil service saw him occupy some of the most senior roles in government. He was Principal Private Secretary to then-Prime Minister Theresa May, Director of Strategy at the Foreign and Commonwealth Office, and worked in the cabinet of European Trade Commissioners Peter Mandelson and Catherine Ashton. He also served as the Prime Minister’s Sherpa for the G7 and G20, and contributed to the Chilcot Inquiry into the Iraq conflict.
Since leaving the civil service, Peter has continued to influence global climate policy and governance. He is founding partner of NorthStar Advisory, Visiting Professor in Practice at the London School of Economics, Associate Fellow of the Institute for Public Policy Research and Chair of Pathways Global, an international climate-focused not-for-profit organisation. His current research explores how countries can accelerate decarbonisation through cooperation.
Speaking about the honour, Peter said: “I’m honoured and surprised! It’s a privilege to be recognised by Royal Holloway, and I hope this inspires more collaboration on the urgent challenges of climate change and sustainability.”
The orator for the award was Professor James Sloam from Royal Holloway’s Department of Politics, International Relations and Philosophy, who praised Peter’s calm leadership and fearless approach to tackling global challenges.
Professor Sloam said: “Peter has brought integrity and vision to some of the most demanding roles in government. His work at COP26 and beyond has helped galvanise international action on climate change at a critical moment for our planet.”
Today, through his academic research and leadership roles, Peter continues to drive progress on sustainability and global cooperation. His career reflects a commitment to public service and a determination to create positive change on a worldwide scale.
