The Monetary Authority of Singapore (MAS) has announced the appointment of Abigail Ng as Chief Sustainability Officer (CSO), effective 6 October 2025. She will succeed Gillian Tan, who has served as CSO since October 2022 while concurrently holding the role of Assistant Managing Director (Development & International).
During her three-year tenure, Tan led MAS’ Sustainability Group in launching the Finance for Net Zero Action Plan, which aims to mobilise capital to support Asia’s transition to a low-carbon economy. Under her leadership, the Group also spearheaded several flagship initiatives, including the Singapore-Asia Taxonomy to harmonise sustainable finance standards, the Transition Credits Coalition (TRACTION), the Financing Asia’s Transition Partnership (FAST-P), and the Sustainable Finance Jobs Transformation Map to strengthen skills in sustainable finance.
With MAS’ sustainability agenda now moving into a more mature phase, the authority said the handover marks the right time to establish a dedicated CSO role. Ms Tan will continue as Group Head of the Development & International Group.
Abigail Ng, who currently leads MAS’ Markets Policy & Consumer Department, has extensive experience in sustainability policy. She has worked closely with international organisations and stakeholders to advance sustainability disclosure frameworks and requirements, positioning her to steer MAS’ sustainability strategy in its next chapter.
