Kathryn Khamsi, a partner in the Paris office of Three Crowns, will chair a seminar on “Emissions Trading: International Law and Dispute Resolution.” The virtual event, hosted by the British Institute of International and Comparative Law (BIICL) in collaboration with Three Crowns, takes place on Wednesday, 18 November, from 1:00 to 3:00 pm UK Time.

In April of this year, the COP26 UN climate change conference set to take place in Glasgow in November 2020 was postponed due to COVID-19. One consequence: agreement on the rules for a global emissions trading scheme under Article 6 of the Paris Agreement will be deferred again, to at least 2021. As agreement under Article 6 has been delayed in the past, various groups have advocated for increased linking of domestic schemes. The thinking is that this would encourage the creation of a global carbon market, involving a range of State and non-State actors, and thus lead to harmonisation of regulatory standards and lower the costs of reducing emissions.

In that context, Khamsi and an esteemed panel will consider existing international and domestic schemes, as well as the risks to market actors as those schemes evolve and interact, before discussing how these risks may give rise to international disputes.

Three Crowns counsel Leilah Bruton (London) and associate Nicola Peart (Washington, DC) were instrumental in the development of the programme.


Khamsi acts for states and corporate clients in disputes ranging from investment treaty to commercial to State-to-State.  Her practice has a particular emphasis on the energy and natural resource sectors.

Clients have commended Khamsi’s “grasp of the technical detail, and her ability to identify and articulate game changing arguments.”  She is recommended by Who’s Who Legal as a leader in the energy field, as well as by The Legal 500.


Bruton has extensive experience acting as counsel for corporations in complex disputes arising out of investment treaties and contractual relationships. She has a particular focus on disputes in the energy and natural resources sectors, including in relation to environmental issues.

Bruton has been recognised by Who’s Who Legal as a “Future Leader” from 2018-2020 and by The Legal 500 (UK 2021) as a “Rising Star” in International Arbitration.


Peart acts as counsel in commercial, investment treaty, and ad hoc arbitrations, and has appeared as counsel before the International Court of Justice, including in matters relating to energy and the environment.

She is a member of the ICC Task Force on Arbitration of Climate Change Related Disputes and has attended the international climate change negotiations since 2009, providing legal support to poor and climate vulnerable developing countries and NGOs.
