Background

About Thomas Oneill

Thomas O’Neill is a climate data entrepreneur and researcher recognised on Forbes 30 Under 30 Europe (Law & Policy) for his pioneering work on corporate climate influence. He is the Founder and Director of Danu Insight, an organisation harnessing AI and large-scale data to uncover how corporate lobbying shapes climate policy. Its flagship database, covering lobbying governance across more than companies, is designed to equip institutional investors with the tools to address systemic risks and steer markets toward a net zero economy. Previously, Thomas co-founded InfluenceMap, where he served as Research Director (2015–2020), building the methodologies behind its global LobbyMap and FinanceMap platforms. His research there informed global investors, regulators, and media outlets including Bloomberg, The Guardian, and Reuters. He also conceived and led FinanceMap, which benchmarked asset managers and funds on climate stewardship and portfolio alignment, earning coverage in the Financial Times and other leading outlets. He began his career at CDP, where he worked on the organisation’s first disclosure questions around corporate climate lobbying, shaping what became a global debate about the gap between corporate climate commitments and political advocacy. Based in Berlin, Thomas holds a degree in Politics and an MSc in International Security and Global Governance from Birkbeck, University of London. His background includes training with the British Army, work in the Metropolitan Police, and a longstanding focus on the intersection of climate, governance, and international security.
