NERA is pleased to sponsor London International Disputes Week (LIDW) 2026 and to co-host a series of expert-led sessions addressing the economic, valuation, and damages issues that increasingly define complex international disputes. Across litigation, competition, ESG, and tax, these sessions bring together leading lawyers and economists to explore practical insights at the intersection of law and economics.

Carbon Offsets and Corporate Carbon Neutrality Claims: Disputes and Quantum Issues

Registration 11:00 | Seminar 11:30–13:00
Tower Place West, 5 Lower Thames Street, London | Herbert Smith Freehills Kramer LLP and NERA

Join NERA Senior Managing Director George Anstey, Herbert Smith Freehills Kramer Of Counsel Louise Barber and Partner Craig Tevendale, and South Pole General Counsel Kushal Bhimjiani in a session that will consider the developing disputes connected with the voluntary carbon market and sustainability claims made in reliance on investments in carbon offsets. The discussion will also examine the complex quantum and valuation issues that arise in disputes involving carbon offsets, including how such instruments are assessed and valued in contentious proceedings.

Using Competition Law and Economics to Enhance Your International Dispute Resolution Toolkit

Registration: 8:30 | Seminar: 9:00–10:30
Tower Place East, 5 Lower Thames Street, London | Monckton Chambers and NERA

Competition law and economics provide a valuable framework for parties involved in a wide range of international disputes. Join NERA Senior Managing Director Grant Saggers and Monckton Chambers Barrister Kassie Smith KC as they present substantive examples of techniques used by leading competition barristers, economists, and solicitors.

The discussion will demonstrate how a competition framework can be applied to:

• Define relevant markets and trade affected by disputed government interventions;
• Disentangle the effects of a disputed event from other contemporaneous factors;
• Model how markets or prices would have evolved in the counterfactual scenario, providing a coherent benchmark against which damages can be measured;
• Measure the effects on different levels of a supply chain (e.g., pass-on and lost profit issues);
• Measure the effects of subsidies and tariffs on trade between countries; and
• Measure the present value of future damage (discounting).

International Tax Disputes: Navigating Challenges and Opportunities in Dispute Resolution

Registration: 11:30 | Seminar: 11:45–13:00
Pinsent Masons LLP, 30 Crown Place, London | Pinsent Masons LLP and NERA

Join NERA Senior Managing Director Emmanuel Llinares and Managing Director Amanda Pletz, Pinsent Masons Partners Jake Landman and Sylvia Tonova, Maisto e Associati Partner Professor Guglielmo Maisto, and Temple Tax Chambers Barrister Jonathan S. Schwarz in a session that will explore the evolving landscape of international tax disputes and the practical considerations facing taxpayers and advisers when resolving cross‑border tax controversies. The discussion will focus on established and emerging dispute resolution mechanisms.

Topics will include:

• Mutual agreement procedures, including the process involved and key challenges faced by taxpayers; and
• The role of international arbitration in resolving treaty disputes and the circumstances in which such matters may transition into investor‑state disputes.
