Asia Pacific Leads Global Sustainability Reporting, but ACCA Warns Implementation Is the Real Test

Asia Pacific is moving faster than any other region in adopting global sustainability reporting standards, but a new report from the Association of Chartered Certified Accountants (ACCA) cautions that regulatory compliance alone will not deliver decarbonisation, energy security or economic resilience. The study, titled Asia Pacific Builds a Sustainable Future: Resilience in Economy, Environment and Society, argues that businesses and governments must translate sustainability commitments into tangible investment and long-term business value.

According to the research, more than 80% of ASEAN economies measured by GDP have adopted or plan to adopt standards issued by the International Sustainability Standards Board (ISSB). When Chinese mainland is included, adopting economies represent roughly US$60 trillion, or about 47% of global GDP. Helen Brand OBE, ACCA's Chief Executive, said the region is building the architecture of sustainability reporting faster than anywhere else, while stressing that adopting standards is not the same as achieving decarbonisation.

The findings carry particular weight for Pakistan, where economic recovery and the energy transition are increasingly tied to climate resilience and sustainable investment. The report notes that Pakistan's economy grew 3.65% in FY2025-26, while installed electricity generation capacity reached 49,651MW, including 7,319MW from solar net metering — a sign of the growing role of distributed renewable energy. At the same time, Pakistan remains exposed to floods, extreme heat, water stress and glacial melt, with direct implications for agriculture, infrastructure and livelihoods.

The report identifies financing constraints, grid integration, energy storage, project bankability and limited institutional capacity as key obstacles to the transition. It argues that decarbonisation should be viewed not only as emissions reduction but as a tool for energy security, helping businesses and governments manage fossil-fuel price volatility, geopolitical disruption and supply-chain shocks. Renewable generation and storage, the authors say, should be treated as strategic economic priorities backed by financing mechanisms that make projects commercially viable.

Sharath Martin, Senior Policy Consultant at ACCA Asia Pacific, said roundtable participants consistently called for a change in narrative: the focus should be on making businesses more resilient rather than on disclosures for their own sake. The report also highlights the role of sustainability disclosures in attracting investment and maintaining access to international markets, noting Pakistan's phased adoption of IFRS Sustainability Disclosure Standards and ESG disclosure guidelines by the Securities and Exchange Commission of Pakistan.

Water scarcity and extreme heat are flagged as potentially defining economic risks of this century. The report warns that, if left unaddressed, water and heat-related risks could cut GDP by 10–15% in lower-income countries by 2050, while floods alone accounted for more than half of the 7.2 billion people affected by disasters across Asia Pacific between 1970 and 2024. ACCA calls on businesses to embed climate and nature-related risks into strategy, budgets and investment decisions, and urges policymakers to mobilise capital, strengthen reporting and assurance capacity, and accelerate renewable energy investment. The report draws on interviews and roundtable discussions with 44 finance and accountancy professionals and subject experts.
