IISD Model International Agreement on Investment for Sustainable Development

The IISD Model International Agreement on Investment for Sustainable Development provides a comprehensive legal framework designed to align foreign investment with sustainable development goals. It moves away from the traditional focus on solely protecting foreign capital by introducing binding investor obligations, including environmental and social impact assessments, anti-corruption requirements, and adherence to core labour standards. The model establishes a new institutional structure featuring a Conference of the Parties, a Secretariat, and a reformed Dispute Settlement Body with a standing panel of arbitrators and an appellate division to ensure transparency and accountability. It explicitly protects the right of host states to regulate for public welfare objectives, such as public health and the environment, and introduces mechanisms for the abrogation of investor rights in cases of persistent non-compliance.

• The document argues that the existing model for international investment agreements (IIAs), developed in the 1950s and 1960s, is outdated and focused exclusively on the "protection of foreign capital and investments," failing to meet 21st-century needs.
• The model agreement introduces binding obligations for investors, requiring them to comply with environmental and social impact assessments prior to establishment, applying the "precautionary principle" to these assessments.
• Investors are required to adhere to specific post-establishment standards, including maintaining an environmental management system (with ISO 14001 certification for companies over 250 or 500 employees or high-risk enterprises) and upholding core labour standards from the 1998 ILO Declaration.
• The agreement establishes a reformed dispute settlement mechanism to replace the current investor-state arbitration process, featuring a standing body of 35 panelists appointed by lottery and a permanent appellate division.
• Host states retain the inherent right to regulate for legitimate public welfare objectives, and such non-discriminatory regulatory measures for public health, safety, and the environment do not constitute indirect expropriation.
• The model introduces a mechanism for the abrogation of investor rights if an investor breaches anti-corruption obligations or persistently fails to comply with environmental, social, or corporate governance obligations.
• Home states are obligated to ensure their legal systems allow for civil liability actions against investors for damages, personal injuries, or loss of life caused in the host state, specifically requiring the removal of constraints like the 'forum non conveniens' rule.
• The agreement mandates transparency in dispute proceedings, requiring that all pleadings, evidence, and decisions be made available to the public via the Internet and that oral hearings be open to the public.
• A Legal Assistance Centre is proposed to provide confidential legal advice and capacity building for developing and least-developed countries in responding to investor claims or initiating procedures against investors.
