The Sustainable Trade and Investment Law Initiative
The Sustainable Trade and Investment Law Initiative (STILI) is a dynamic programme dedicated to exploring the intersections between international trade, investment, and financial regimes with sustainable development objectives. Led by Legal Counsel Prof. Markus Gehring and coordinated by the Centre for International Sustainable Development Law (CISDL), STILI engages in cutting-edge legal research and analysis to understand how these frameworks can be aligned—or are currently misaligned—with the achievement of climate goals, environmental protection, and social equity. In particular, STILI examines the legal and policy dimensions of international economic agreements to identify opportunities and barriers to the implementation of the Paris Agreement and countries’ Nationally Determined Contributions (NDCs).
This project aims provide legal analysis and informed, engaged communities of practice to promote the highest level of climate ambition and sustainable development in the negotiation and update of EU trade and investment agreements. It generates technical analysis of EU economic agreements, comparing key provisions to global best legal practices, evaluating ongoing negotiations and encouraging meaningful, binding new climate commitments. The communities of practice includes negotiators, legal and policy experts, practitioners, and academics. By strengthening legal communities of practice on climate change and sustainable development, it builds legal expertise to help shape climate aspects of trade and investment debates in the EU, in partner countries and regions (such as Mercosur and Central America countries) and beyond. By enabling legal experts and communities of practice to engage with key ECF and broader networks, it helps to draft, in concrete textual terms, the contours of trade agreements better aligned with climate change objectives.
Recognizing the complex geopolitical landscape and competing global priorities, the initiative also seeks to offer innovative, practical, and legally robust pathways to advance sustainability through economic law. Its global network of legal scholars and practitioners—from Latin America, Europe, New Zealand, and other regions—collaborates on policy briefs, capacity-building, and high-impact publications. Notably, STILI has contributed to two special journal issues: Legal Issues of Economic Integration (2023) and the upcoming issue of the European Foreign Affairs Review (2025). For more insights into the initiative’s ongoing work, see the latest CISDL reports here.
Objectives
- Identify highest priority climate change challenges for key upcoming trade agreement negotiations (Mexico, Chile, Central America, Colombia, and Peru), and undertake careful legal analysis based on existing climate and sustainability related commitments in economic treaties, including existing commitments by the EU (eg, its TCA with the UK) and broader EU climate ambition (eg, the Green Deal);
- Draft a legal technical paper providing an analysis of proposed climate and trade provisions to advance climate ambition in future EU trade agreements, summarizing options for concrete technical text proposals, including the NZ proposals and CBAM options, and publish the paper over social media and partners websites;
- Convene online legal roundtables among trade, environment and climate law experts in the target jurisdictions of the Americas with potential to influence negotiations, to explore options, challenges, and areas of opportunity for changes, consulting law and policy experts and leaders, generating a short, clear report offering legal drafting options, and supporting their participation in ECF decision-maker dialogues and their efforts to inform key countries and regional institutions involved in new trade and investment negotiations.

CISDL has previously organised 4 expert online roundtables dedicated to four main EU trade relations:
