Trade, investment and financial laws and policies could foster or frustrate sustainable development. Global economic growth is slowly resuming, and in 2021 world merchandise exports rose 8%. Alongside global rules and continuing, though hampered, dispute settlement in the World Trade Organization (WTO), global flows of foreign direct investment only recovered to pre-pandemic levels in 2022, reaching $1.6 trillion (UNCTAD 2022 World Investment Report), and 796 Regional Trade Agreements (RTAs) were notified (WTO RTA Gateway) in 2022. There is new impetus for international economic law to support a global green economy, and significant potential for international legal innovation. With slow progress in global trade round negotiations, widespread trade skepticism, Brexit, the growth of protectionism and the breakdown of the WTO dispute system new forms of economic cooperation are being developed and economic nationalism being opposed. 

While a growing web of RTAs increasingly recognize sustainable development objectives; create exceptions for health, environment, natural resources and other public policies; address sustainability aspects of procurement, intellectual property rights, subsidies and investments; move from referencing climate change to making it an essential element, environmental goods, services and technologies; encourage sustainable energy, forestry and other resources use; highlight corporate social responsibility; and seek mutual supportiveness with social and environmental policies, these new ‘progressive’ trade agreements will be the focus of the research, especially when advancing the economic interests of indigenous peoples. Research into the impacts and opportunities of international investment law for sustainable development, and the possibilities for financial law, is also expanding exponentially. With many countries reforming their laws and institutions to implement new international instruments for a global green economy, there is a pressing need for legal expertise, capacity and advice.

In contribution to global efforts, through our Trade, Investment and Finance Programme in 2022-2027, CISDL aims to:

  • Advance knowledge and understanding of international trade law for sustainable development within the context of progressive trade agreements respectful of human rights, indigenous rights, gender equality, climate change and broader sustainability; building global legal research and advisory capacity and disseminating key findings among trade regimes such as the WTO and RTAs.
  • Lead legal research and build capacity to strengthen the contribution of international investment law toward sustainable development and which realises the SDGs and assists in the transition to net-zero, including in the World Bank International Centre for Settlement of Investment Disputes (ICSID), the UN Commission on International Trade Law (UNCITRAL), BITs and investment chapters of RTAs.
  • Analyse the implementation of trade, investment, and financial law regimes, including innovative legal practices and recent disputes related to sustainable banking, energy, aviation, the World Bank, the Energy Charter Treaty, the International Civil Aviation Organization, the International Maritime Organization and other related fora.
  • Research and build capacity on the concept of the global green economy, especially how national and international law facilitates the transition to a greener, carbon neutral, biological diverse economy and how such instruments interact with existing international social, environmental, and economic legal frameworks.
