The Monetary Authority of Singapore (MAS) has announced the appointment of Abigail Ng as its new Chief Sustainability Officer (CSO), effective from 6 October 2025. Ng will succeed Gillian Tan, who has held the dual roles of Assistant Managing Director (Development & International) and CSO since October 2022. This transition marks a significant step in MAS’ sustainability journey, as the organisation seeks to further its commitment to sustainable finance.
Under Tan’s leadership, MAS’ Sustainability Group has made notable strides, including the launch of the Finance for Net Zero Action Plan, which aims to mobilise financing for Asia’s transition to a low-carbon economy. Other key initiatives include the Singapore-Asia Taxonomy, the Transition Credits Coalition (TRACTION), and the Financing Asia’s Transition Partnership (FAST-P), all designed to promote sustainable financing standards and accelerate energy transition in the region.
Ng, currently the Department Head of the Markets Policy & Consumer Department, brings extensive experience in sustainability issues. Her work has involved collaboration with international organisations and stakeholders to develop sustainability disclosure policies. This expertise is expected to bolster MAS’ efforts as it enters a more mature phase of its sustainability agenda.
Tan will continue to lead the Development & International Group as Group Head, ensuring continuity in MAS’ broader strategic initiatives. The appointment of a dedicated CSO reflects MAS’ commitment to advancing its sustainability objectives in a rapidly evolving financial landscape.
