Investor-State Arbitration and Climate Challenges 🌎👨🏼⚖️
Fawcett 9.04, Grantham Research Institute on Climate Change and the Environment, London, WC2A 2AZ
Wednesday 5th November 2025
Legal Voices for the Future presents our first November 2025 Knowledge Session on Investor-State Arbitration and Climate Challenges 🌎👨🏼⚖️, hosted in partnership with the Grantham Research Institute on Climate Change & the Environment and led by WilmerHale Senior Associate Xiaohan Cai and LVF Stewardship Committee member Carol Yuen.
The session, happening on 5 November 2025 (Wednesday) at 6.30pm, will discuss the challenges of States balancing obligations to foreign investors in energy and mining projects with State duties to combat climate change and environmental degradation. The session will also critically look at whether the current investment treaty system is an obstacle or could be a vehicle for the urgent energy transition.
Join us in person in Room FAW 9.04 in the Fawcett House Building on the LSE campus (a map of the campus showing the FAW building can be found here) or online (the joining link is below).
Creative content
We will start this session by screening the first 10 minutes of a short documentary called The Tribunal, and have a breakout discussion at the end of the knowledge session (after the presentation and panel). Our discussion questions will relate to the entire knowledge session. If you have some time, we encourage you to watch the whole documentary (which is only 30 minutes long!) beforehand.
Presentation
The presentation, given by Xiaohan Cai, will introduce the investor-state dispute settlement (ISDS) framework and institutions. It will explain the obligations of States to foreign investors (for instance in bilateral investment treaties (BITs) and the Energy Charter Treaty), and how these obligations may conflict with State obligations on climate change.
The presentation will also give an overview of recent developments in relation to arbitral tribunals’ consideration of States’ environmental regulatory duties, energy transition and critical minerals, and sustainable investments.
Panel discussion
We will be joined by an expert panel from private practice and academia to discuss the impact of investor-state arbitration on climate change and the environment, and potential reforms in ISDS.
