Singapore’s upcoming chairmanship of the Association of Southeast Asian Nations (ASEAN) in 2027 is expected to prioritize sustainability and regional energy integration amid ongoing global challenges. During a recent discussion at the Association of Chartered Certified Accountants (ACCA) annual conference on October 9, Ramesh Singh, a key figure in ASEAN economic affairs, outlined plans to leverage the chairmanship to advance clean energy adoption and enhance regional cooperation.
Singh highlighted energy security as a critical issue for Southeast Asia, particularly given the region’s vulnerability to disruptions originating from the Middle East. Around 80% of the oil transported through the Strait of Hormuz, which services much of Southeast Asia, was at risk during recent conflicts, causing anxiety over supply stability. Although commodity prices and supply chain disruptions earlier in the year led to inflation in some ASEAN countries, these factors have since stabilized.
The regional economy nevertheless showed resilience, growing nearly 5% in 2025, according to ACCA’s Asia-Pacific public affairs manager George Thomson. As the Philippines concludes its 2026 chairmanship, Singapore is set to assume the role with a focus on sustainability and digital integration.
A cornerstone of Singapore's agenda will be the implementation of the Digital Economy Framework Agreement (DEFA), scheduled for signing at the 49th ASEAN Summit in November 2026. The agreement aims to harmonize digital trade rules, including cross-border data flows, supporting the broader goal of regional economic integration. Alongside DEFA, efforts will intensify on the Green Economy Framework Agreement (GEFA), which guides cooperation on emerging green industries.
Singh stressed that Southeast Asia currently lags behind in renewable energy use, with renewables constituting just about 12% of the region’s total primary energy supply, compared to a 20% global average. To address this gap, Singapore plans to promote an innovative regional cooperation framework aimed at reducing greenhouse gas emissions from power generation, transportation, buildings, and waste management. This includes encouraging the adoption of renewables such as offshore wind and solar power, as well as investments in clean fuels like bioenergy, hydrogen, and ammonia.
The ASEAN Power Grid, a long-discussed initiative facilitating cross-border electricity trade, is poised for renewed momentum under Singapore’s leadership. The grid would enable countries with abundant renewable resources, such as Cambodia, Laos, and Myanmar, to supply cleaner electricity to more industrialized economies including Thailand, Indonesia, Malaysia, Singapore, and the Philippines. This integration is expected to optimize energy production and consumption, reducing reliance on fossil-fuel-based electricity generation.
Singh also emphasized the need for balanced progress to ensure no member state is left behind as the region adopts advanced technologies and deepens market integration. He underscored the importance of connectivity and smart grid technologies to support this transition.
Beyond energy and sustainability, Singh called for enhanced collaboration in professional services across ASEAN. Despite mutual recognition of qualifications like those from ACCA, legal and regulatory barriers persist, constraining mobility and cross-border practice for professionals. With digital transformation, artificial intelligence, and sustainability reporting reshaping the sector, Singh urged for greater inclusivity and interoperability to meet growing regional demands for specialized skills.
As the world’s major economies advance their energy transitions, ASEAN’s collective approach under Singapore’s 2027 chairmanship aims to balance immediate energy security concerns with long-term sustainable growth strategies. The forthcoming chairmanship intends to position Singapore as a hub linking innovation, market demands, and regional cooperation within ASEAN.
