Summary: Singapore's phased climate reporting framework gives companies a clear path to mandatory ISSB-aligned disclosure, beginning with SGX-listed issuers and extending to large non-listed companies later. For supply chain and ESG teams, the key takeaway is that climate reporting capability now requires reliable data governance, cross-entity visibility, and controls that can support overlapping obligations in Singapore, the EU, and other jurisdictions.
Singapore’s mandatory climate reporting framework is now operational. As of 2025, SGX-listed companies must disclose climate-related information. These disclosures align with the International Financial Reporting Standards (IFRS) Sustainability Disclosure Standards issued by the International Sustainability Standards Board (ISSB). As a result, Singapore became the first Southeast Asian jurisdiction to mandate ISSB-based reporting.
This landmark requirement extends to large non-listed companies by 2027. Specifically, it covers companies with at least S$1 billion in revenue and S$500 million in assets. The framework marks a significant maturation of Singapore’s regulatory approach to climate risk. Moreover, it reflects a global convergence toward standardized, investor-grade sustainability disclosure.
For multinational enterprises with operations or supply chains in Singapore, this climate reporting framework intersects with parallel obligations. These include the EU’s Corporate Sustainability Reporting Directive (CSRD), the Corporate Sustainability Due Diligence Directive (CSDDD), and Germany’s LkSG. Consequently, robust climate data infrastructure has become a shared compliance requirement across multiple jurisdictions.
A Phased Approach to Transparency
Singapore implemented its mandatory climate reporting requirements through a phased approach. This design gives companies time to build reporting capability while setting clear accountability milestones. SGX-listed companies began their climate reporting obligations in financial year 2025. Their requirements cover IFRS S2 (Climate-related Disclosures), including governance, strategy, risk management, and metrics and targets.
Large non-listed corporations must comply by 2027. Specifically, this covers those generating at least S$1 billion in revenue and holding S$500 million in assets. The phased structure mirrors the rollout approach the EU adopted under CSRD. Similarly, it reflects the understanding that building robust climate data infrastructure demands sustained organizational investment.
The Roadmap for Sustainability
The mandatory framework follows recommendations from the Sustainability Reporting Advisory Committee (SRAC). Singapore established this committee to guide sustainability reporting advancements. The SRAC’s phased approach provides a structured roadmap for companies to enhance their climate reporting practices. Additionally, it contributes to Singapore’s Green Plan 2030 — a whole-of-government sustainability blueprint targeting net-zero emissions by 2050, clean energy transition, and green economy development.
Most importantly, SRAC’s recommendations aligned Singapore with the ISSB’s global baseline standards (IFRS S1 and S2). This alignment ensures comparability with the TCFD-aligned frameworks already embedded in EU CSRD requirements. International institutional investors have also widely adopted these standards.
The convergence between Singapore’s ISSB-aligned framework and the EU’s CSRD creates practical benefits. Multinational companies can leverage shared data collection and reporting infrastructure. In fact, this shared approach reduces the duplication of effort that has historically burdened global sustainability reporting programs.
Furthermore, supply chain compliance teams should note an important shift. Singapore’s framework will increasingly require Scope 3 GHG emissions data from major suppliers. This mirrors CSRD requirements. As a result, demand for supplier ESG assessment and audit capability throughout Southeast Asian supply chains continues to grow.
Benefits Beyond Compliance
The primary goal of Singapore’s mandatory climate disclosures is to provide investors with transparent climate-related financial information. However, the benefits extend well beyond regulatory compliance. Companies that effectively measure, manage, and disclose greenhouse gas emissions stand to gain improved access to green financing, new markets, and sustainability-focused customers.
Notably, Singapore’s Green Finance Action Plan targets S$50 billion in green and sustainable loans by 2030. The Monetary Authority of Singapore (MAS) oversees this initiative. It creates direct financial incentives for companies with robust climate reporting. Moreover, the SRAC’s foundational analysis identified a US$146.6 billion commercial opportunity for companies in the region that demonstrate credible sustainability commitments.
For supply chain leaders, Singapore’s climate reporting framework also drives upstream visibility requirements. Companies disclosing under IFRS S2 must account for climate-related risks in their supply chains. Therefore, they have strong incentives to conduct systematic supplier risk assessments. These assessments align with what CSDDD and LkSG require from the EU side. In other words, investing in integrated supply chain sustainability infrastructure satisfies multiple regulatory frameworks at once.

Preparing for a Greener Future
Singapore’s government has actively supported companies in building climate reporting capability. The Ministry of Trade and Industry (MTI) and Enterprise Singapore have deployed capability-building programs and grants. These help businesses develop climate measurement and reporting competencies. In particular, they target SMEs operating in complex supply chains.
Additionally, professional training programs aligned with ISSB standards are increasingly available. Singapore’s universities, industry associations, and professional bodies offer these programs.
As Singapore’s mandatory climate reporting enters its operational phase, companies that have invested in digital sustainability data infrastructure hold a significant advantage. On the other hand, those relying on manual data collection, spreadsheet-based reporting, or fragmented supplier data systems face substantial operational risk. This risk grows as reporting obligations expand to cover more entities and more granular data in 2027 and beyond.
Ultimately, Singapore’s mandatory climate reporting is not just a compliance requirement. It is a catalyst for the organizational and technological transformation needed to thrive in a net-zero global economy.

Frequently Asked Questions (FAQs)
What companies are required to report under Singapore’s mandatory climate reporting framework?
Singapore’s mandatory climate reporting framework applies in phases. SGX-listed companies must disclose climate-related information aligned with IFRS S2 (Climate-related Disclosures) beginning with financial year 2025 reporting. Large non-listed companies — those with at least S$1 billion in revenue and S$500 million in total assets — must comply by financial year 2027. The framework will likely extend further over time as Singapore aligns with global ISSB adoption trends.
What is the ISSB and why does it matter for Singapore’s climate reporting?
The International Sustainability Standards Board (ISSB) is an independent standard-setting body under the IFRS Foundation. It was established in 2021 to develop a global baseline of sustainability disclosure standards. The ISSB published IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) in June 2023. Consequently, Singapore’s alignment with ISSB standards ensures that its mandatory climate disclosures are comparable with those from other ISSB-adopting jurisdictions. These include the EU (where CSRD incorporates ISSB compatibility) and Japan. This comparability facilitates cross-border investor analysis and capital allocation decisions.
How does Singapore’s framework relate to EU CSRD?
Both Singapore’s ISSB-aligned framework and the EU CSRD share common foundations. These include TCFD’s four-pillar framework (governance, strategy, risk management, metrics and targets), Scope 1, 2, and 3 GHG emissions disclosure, and third-party assurance of sustainability information. Multinationals operating in both Singapore and the EU can leverage shared data infrastructure and reporting processes. However, CSRD requires additional double materiality assessment and more detailed social and governance disclosures beyond the climate-focused ISSB baseline.
What does Singapore’s mandatory climate reporting mean for supply chains?
Singapore’s IFRS S2-aligned framework requires companies to disclose climate-related risks and opportunities across their entire value chain. This includes supply chain climate risks and Scope 3 upstream emissions. As a result, this creates demand for supplier climate data and ESG assessments. It also drives supply chain transparency requirements similar to those emerging from EU CSRD and CSDDD. Suppliers to Singapore-listed companies should therefore anticipate requests for GHG emissions data, climate risk information, and ESG audit participation as part of their customers’ regulatory reporting obligations.
