Symposium on International Investment Law & Contemporary Crises – Part 6 of 8
Energy Finance Market Design & IIA Claims

As climate regulation intensifies, how might energy finance measures trigger investment treaty claims?

In this afternoon’s symposium contribution, Freddy Sourgens (Tulane University Law School) bridges two critical systems: energy market design and international investment law.

Drawing on the BIICL (British Institute of International and Comparative Law) empirical study, the piece explores how State interventions in energy finance—particularly in the context of climate policy, climate finance, and sanctions—may attract scrutiny under international investment agreements (IIAs).

Three areas stand out:

- Climate-related lending restrictions—Could limits on fossil fuel financing expose States to treaty claims by foreign lenders?
- Climate finance structures—What happens when shifts in national energy policy undermine financing assumptions underpinning climate-backed projects?
- Sanctions regimes—Can lenders challenge sanctioning States where financial restrictions disrupt protected investments?

The study’s findings on emergency measures, police powers, sovereign debt analogies, and proportionality offer a structured lens through which tribunals may assess such disputes.

The core message? Investment treaty arbitration may operate as an under-estimated guardrail in the design of energy and energy finance markets—especially during the global energy transition.
