Launched in December 2016, the Sustainable Insurance Forum (SIF) is a network of insurance supervisors and regulators from around the world who are working together on sustainability challenges facing the insurance sector. The United Nations Environment Programme serves as the SIF Secretariat. Since its inception, the SIF has evolved into a dynamic platform for international collaborative action on climate issues. This has resulted in research on emerging risks, knowledge-sharing on supervisory practices, high-level policy engagement, and joint supervisory statements. In 2020, the SIF continued to gain momentum with four new members joining since January 2020, bringing the total membership to 30. Building on the progress to date, in March 2020 members endorsed the prospect of SIF continuing its work, through a new phase running from 2021- 2023. Finalized by the end of July, the development of a 2021-2023 work plan is currently under way. Despite the challenges posed by COVID-19, SIF members have continued to drive the sustainability agenda in their respective jurisdictions. This update covers some of the exciting work being carried out by the SIF members.
