On 24 November 2023, the Centre for International Law (CIL), the Organisation for Economic Co-operation and Development (OECD) and University College London (UCL) jointly organised an in-person, closed-door, off-the-record meeting on investment treaties and climate change for ASEAN-Plus government officials in Singapore. This in-person meeting was a follow up to a virtual meeting held on 25 May 2023, which focused on the investment treaty regime, its impact on high-carbon and other investment incentives, and its interaction with policies designed to mitigate and adapt to climate change. Following an introductory presentation of the Paris Agreement and key recent climate developments, the in-person meeting proceeded to discussion of whether investment treaties can contribute to addressing climate change, and how to ensure that investment treaties do not hinder the achievement of climate goals.
