The Securities and Exchange Regulator of Cambodia has stepped up its regional engagement on sustainable finance, with senior officials participating in high-level ASEAN discussions in Manila focused on the future direction of the ASEAN Taxonomy and its practical implementation across capital markets.

A delegation led by Sou Socheat, Director General of the Securities and Exchange Regulator of Cambodia, attended meetings and technical workshops in the Philippines on January 23. The sessions brought together regulators and market authorities from across Southeast Asia to review the 2026 implementation roadmap for ASEAN Taxonomy Version 4 and to align approaches to climate mitigation, adaptation and resilience financing.

Reviewing the ASEAN Taxonomy Version 4 Roadmap

At the core of the discussions was the review of the 2026 work plan for ASEAN Taxonomy Version 4, the region’s evolving framework for classifying sustainable economic activities. As a member of the Alternative ASEAN Taxonomy Board, Sou Socheat joined counterparts in assessing priorities for the next phase of implementation, including how the taxonomy can better support capital flows into climate-aligned investments.

Participants examined ways to strengthen capacity building among regulators, financial institutions and market participants, recognising that effective taxonomy adoption depends not only on technical design but also on market understanding and consistent application.

Advancing Interoperability With Global Frameworks

A key theme of the Manila meetings was interoperability. Regulators discussed expanding consultations with relevant stakeholders to ensure that the ASEAN Taxonomy can align more effectively with other regional and global taxonomies. Improving compatibility is seen as essential for attracting cross-border investment and reducing friction for issuers and investors operating across multiple markets.

By positioning the ASEAN framework alongside international standards, the region aims to enhance credibility, comparability and investor confidence while retaining sensitivity to Southeast Asia’s development needs.

Focus on Mitigation, Adaptation and Resilience

Alongside the taxonomy board meeting, delegates participated in a dedicated workshop on the Mitigation, Adaptation, Resilience and Sustainable Finance Guide. The session outlined implementation plans for assessing Environmental Objective 2 under the ASEAN Taxonomy, with an emphasis on translating high-level climate goals into practical evaluation criteria for financial activities.

The mARs Guide initiative is being developed jointly by the Alternative ASEAN Taxonomy Board and the ASEAN Capital Markets Forum. Its objective is to promote consistent and robust sustainable finance practices across ASEAN capital markets, particularly in areas where climate resilience and adaptation are becoming increasingly important.

Cambodia’s Role in Regional Sustainable Finance

Cambodia’s participation reflects a broader effort by the country’s capital markets regulator to stay aligned with regional sustainable finance developments. By engaging directly in the design and rollout of ASEAN-wide standards, SERC is positioning itself to support domestic market readiness while contributing to regional coherence.

As ASEAN moves toward the next phase of taxonomy implementation, discussions in Manila underscored a shared recognition that sustainable finance frameworks must balance ambition with practicality. For regulators like SERC, the focus is now shifting from framework design to execution, capacity building and regional alignment, laying the groundwork for more credible and scalable sustainable finance across Southeast Asia.
