Prof Lavanya Rajamani

Yamani Fellow and Tutor in Public International Law

Professor of International Environmental Law

I am the Yamani Fellow in Public International Law at St Peter’s, and a Professor of International Environmental Law at the Law Faculty. I did my graduate studies in Oxford, taught in Cambridge, and worked at the Centre for Policy Research in New Delhi before joining St Peter’s and the Law Faculty in the summer of 2019. 


In college, I teach Public International Law and Jursiprudence, and at the Law Faculty I lecture on Public International Law to the undergraduates, and run a seminar on International Environmental Law for the graduates (B.C.L and M.Jur). 


My research is focused on international environmental law, in particular international climate change law. I have worked extensively on the international climate change negotiations. I have represented small island states, advised climate change negotiators from around the world, and provided legal expertise to the United Nations Climate Secretariat, including as part of the core drafting and advisory team for the 2015 Paris Agreement.

My expertise lies in drafting constructively ambiguous compromise language in the vanishingly small sweet spot between the red lines of states. The dysfunctional politics of the international climate negotiations have led to considerable innovation and experimentation in the legal character of obligations, in differentiation between developed and developing states, and even in the processes and procedures used to organise multilateral negotiations. My research explores the ways in which the international climate change regime, and innovations within it, are shifting the boundaries of international law.

I have authored several books and articles in this field. My latest co-authored book, International Climate Change Law won the 2018 ASIL Certificate of Merit in a Specialized  Area of International Law. I delivered a Hague Academy Special Course on the International Climate Change Regime in July 2018, which will feature in the Collected Courses of the Hague Academy of International Law, under the title, Innovation and Experimentation in the International Climate Change Regime. I also serve as Coordinating Lead Author for the Intergovernmental Panel on Climate Change’s Sixth Assessment Report.
