Tan heads CWR, a non-profit that aims to “mainstream” water and climate risks into financial decision-making and corporate strategies. She built CWR from an idea into a 'go-to' resource in the global climate water risk conversation. Today, CWR’s work on assessing and valuing risk exposure to rising freshwater scarcity to coastal threats, is highlighted as tools and useful resources under the IFRS’s CDSB Application Guidance for Water-Related Disclosures, TCFD Knowledge Hub and featured in Palgrave MacMillan textbooks. CWR as well as Tan are widely cited by IGOs, the financial sector as well as mainstream media. Besides the numerous ground-breaking reports she had curated/written for CWR and financial institutions, Tan is also published by SpringerNature, China policy journals and was a contributing author to the latest IPCC 6th Assessment Report: “Climate Change 2022: Impacts, Adaptation and Vulnerability”. Before water, Tan spent over a decade in finance. She spends her spare time exploring Himalayan glaciers.
