Personal profile

My research in a nutshell

As a climate lawyer my primary research foci are on the regulation of carbon dioxide removals (CDR) and climate constitutionalism. I am an interdisciplinary scholar and routinely co-author with non-lawyers and/or practitioners. My research profile extends across the breadth of climate law, including international regulatory regimes (on the Paris Agreement here and here), regions (e.g. Asia, and EU), institutions (UK Supreme Court, Export Credit Agencies, UNFCCC), technologies (CCS), and legal approaches/practices (Just Transitions, theory, and definitions).


I have been at Edinburgh Law School since 2003. Previously a barrister in London and Lecturer at King's College London, I undertook my graduate work at the University of Cambridge, the European University Institute (Florence) and the University of California, Berkeley (Fulbright Scholar). 

Current and past community roles include: Director of Alumni Relations; Head of Public Law Subject Area; Convenor, Equality Diversity and Inclusion committee, Society of Legal Scholars (and Executive Committee member); Board Member and Chair of Climate Strategies.

3. Constitutional Clauses - project to develop climate/net zero constitutional clauses, esp in the global south. Funding University of Edinburgh/philanthropies. See here. Principal Investigator. 

I have been funded by a wide range of research funders (public, private, philanthropic, domestic, and international). These include:
European Commission/Horizon Europe; Economic and Social Research Council; Natural Environment Research Council, the British Academy, Daiwa Foundation, UK Energy Research Council, Laudes Foundation, and the KR Foundation.


My research and practices areas deeply influence my teaching in the Global Environment and Climate Change graduate LLM programme, which I have long directed (but no longer!), integrating  cutting edge legal thinking with climate research in cognate disciplines including finance and geosciences.

In 2023/24 I will lead the following modules:
International Climate Change Law (LAWS11245)
Climate Change Litigation: Practice and Theory (LAWS11421)

I also teach on the Business School's Climate Change Risk in Finance

Collaborative Activity

I am a long time member of the leading global research network, Climate Strategies, and chaired its Board from 2020-2023. Climate Strategies has over 100 members (by invitation only) and offices in London and The Hague.

I have also led activist campaigns on climate issues, bringing together influential groupings of concerned academics and scientists. See Open Letter From Climate Scientists.

A significant part of my work consists of engaging with practitioners in the climate world: legal professionals, public bodies, and civil society actors. These engagements include advisory roles, board memberships, and sharing research with stakeholders via presentations or publications. For example, I write the climate law content for LexisNexis and my work has been widely cited and reviewed in the quality press, and parliamentary reports. I advise philanthropic foundations, regulatory agencies, committees, international organisations and industry.
