ESG Reporting in Singapore (2026 Guide): ACRA & SGX Explained

Written by Ascentium Content Team | 19 March 2026

ESG reporting has become an important part of doing business in Singapore. Investors, banks, customers, and regulators increasingly want to understand how companies manage environmental, social, and governance (ESG) issues alongside their financial performance.

Singapore has also introduced new sustainability reporting requirements in recent years. According to ACRA's sustainability reporting roadmap, mandatory ISSB-aligned climate disclosures are being phased in from FY2025, with all listed companies and certain large non-listed companies expected to come within the reporting framework by FY2030. This marks one of Singapore's most significant corporate reporting reforms in recent years.

In this blog, we will explain what ESG reporting is, the latest reporting requirements in Singapore, key ESG frameworks, common reporting challenges, and the practical benefits ESG reporting can bring to businesses.

What is ESG Reporting?

ESG reporting is the process of disclosing information about a company's environmental, social, and governance performance. It helps stakeholders understand how a business manages sustainability-related risks and opportunities alongside its financial performance.

Common ESG topics include:

  • Carbon emissions and energy usage
  • Employee wellbeing and workplace practices
  • Diversity and inclusion
  • Data privacy and cybersecurity
  • Business ethics and corporate governance

The objective is to provide greater transparency and demonstrate how sustainability considerations are integrated into business operations and decision-making.

Why is ESG Reporting Becoming Mandatory for Businesses in Singapore?

ESG reporting in Singapore is becoming mandatory as part of the shift toward ISSB-aligned climate disclosures under ACRA and SGX RegCo.

Key Requirements Under The Latest Roadmap Include:

  • FY2025: All SGX-listed companies must report Scope 1 & 2 emissions
  • FY2025: STI companies must provide ISSB-aligned disclosures
  • FY2026: STI companies must report Scope 3 emissions
  • FY2028: Non-STI constituent listed companies with market capitalisation of S$1 billion and above must report other ISSB-based CRD
  • FY2030: Non-STI constituent listed companies with market capitalisation of less than S$1 billion must report other ISSB-based CRD

Key Drivers Behind Mandatory ESG Reporting

  • Climate risk is now treated as financial risk
  • Global alignment with ISSB reporting standards
  • Stronger investor and lender demand for verified ESG data
  • Supply chain pressure from multinational companies
  • Increased board-level governance and accountability expectations

Singapore supports ESG adoption through funding schemes such as the Enterprise Development Grant (EDG) and the Productivity Solutions Grant (PSG), which help businesses offset the costs of sustainability consulting, carbon reporting tools, and energy-efficiency improvements.

Initiatives such as SME Go Digital and green financing incentives further support digital ESG adoption and low-carbon investments, making it easier for companies to meet reporting requirements and sustainability goals.

ESG Reporting Requirements in Singapore

Singapore follows a phased approach to ESG reporting to give businesses time to adapt. The requirements are gradually increasing in scope and depth.

SGX-Listed Companies

  • Mandatory reporting of Scope 1 and 2 emissions from FY2025
  • ISSB-aligned climate disclosures for STI companies from FY2025
  • Scope 3 emissions required for STI companies from FY2026
  • External assurance requirements for emissions data will be introduced gradually

Large Non-listed Companies:

From FY2030, companies meeting both thresholds must comply:

  • Revenue ≥ S$1 billion
  • Total assets ≥ S$500 million

This phased rollout gives businesses time to build systems, collect data, and strengthen reporting processes.

What Should Be Included in an ESG Report?

An ESG report should provide a clear picture of how a company manages sustainability-related risks and opportunities, and of its business performance. The information disclosed should be relevant, measurable, and aligned with the company's operations and industry.

Most ESG reports typically include:

  • ESG governance structure and board oversight
  • Material sustainability risks and opportunities
  • Greenhouse gas emissions and energy consumption data
  • Climate-related risks and mitigation measures
  • Employee wellbeing, diversity, and workforce metrics
  • Data privacy, cybersecurity, and business ethics practices
  • Supply chain sustainability initiatives
  • ESG targets, performance indicators, and progress updates

Beyond compliance, ESG reporting helps businesses identify risks earlier, improve operational transparency, strengthen stakeholder trust, and support long-term growth.

Key ESG Reporting Frameworks Used in Singapore

Singapore's ESG reporting framework is increasingly aligned with global sustainability standards to improve transparency and consistency across businesses. Depending on their reporting obligations and stakeholder expectations, companies may use one or more of the following frameworks:

Framework

What It Covers

ISSB (IFRS S1 & S2)

The global baseline for sustainability and climate-related disclosures. Singapore is progressively adopting ISSB standards for listed companies and certain large non-listed companies.

GRI Standards

A widely used framework covering environmental, social, and governance impacts across the business.

TCFD Framework

Focuses on climate-related risks, opportunities, governance, and risk management. Many of its principles are now incorporated into ISSB standards.

SASB Standards

Provides industry-specific ESG metrics that help investors assess financially material sustainability issues.

SGX Sustainability Reporting Guide

Offers reporting guidance for SGX-listed companies and recommends key ESG metrics and disclosures.

How Can Companies Prepare for ESG Reporting in 2026?

As ESG reporting requirements continue to expand in Singapore, businesses should start preparing early. Building the right processes now can make reporting easier, improve data accuracy, and reduce future compliance risks.

Some practical steps companies can take include:

  • Identify the ESG reporting requirements that apply to your business.
  • Focus on the ESG issues that have the biggest impact on your operations and stakeholders.
  • Put systems in place to consistently collect and track ESG data.
  • Measure greenhouse gas emissions, including Scope 1, Scope 2, and where applicable, Scope 3 emissions.
  • Assign clear ESG responsibilities to management and key decision-makers.
  • Maintain accurate records and supporting documents for reporting purposes.
  • Set realistic ESG goals and regularly monitor progress.

Where to Next?

ESG reporting is quickly becoming a core part of corporate governance and regulatory compliance in Singapore. With mandatory climate-related disclosures already underway and reporting requirements expanding through FY2030, businesses should start building their ESG reporting capabilities now.

More importantly, ESG reporting is not just about meeting regulatory obligations. It helps businesses improve transparency, strengthen risk management, build investor confidence, and respond to growing stakeholder expectations.

With the right preparation, ESG reporting becomes less of a burden and more of a way to strengthen business performance. Ascentium supports businesses in building practical ESG reporting systems, staying compliant, and adapting to Singapore’s evolving sustainability requirements.
