SET Sustainability Requirements & Guide

What is SET Sustainability?

SET Sustainability refers to the Stock Exchange of Thailand (SET)’s ecosystem of policies, frameworks, and tools designed to integrate environmental, social, and governance (ESG) principles into Thailand’s capital market. This covers how listed companies operate and report, as well as how investors assess long-term value. It supports transparent disclosure, risk-informed investment decisions, and sustainable economic development aligned with global expectations and UN Sustainable Development Goals (SDGs).

The framework spans multiple components, including sustainability governance, sustainable capital market development, social development, climate action, and employee development. It reinforces the concept that ESG is embedded at both system and corporate levels.

What is the SET rating and how is it determined?

The SET ESG Rating program is a voluntary evaluation of listed companies’ ESG performance, producing rating levels such as AAA, AA, A, and BBB. While participation is optional, companies are assessed based on disclosed data and criteria set by SET’s Sustainable Investment Committee. The ratings serve as an additional tool for investors, analysts, and fund managers to compare risk profiles and growth prospects across firms.

Ratings represent performance outcomes, not regulatory mandates
Companies typically need to meet minimum thresholds across all ESG pillars and maintain good governance, among other qualifying conditions
Results are publicly published annually to foster competitive improvement and transparency

Who needs to comply with SET Sustainability requirements?

Compliance with the SET’s Sustainability requirements are categorized as follows:

Mandatory compliance (regulatory disclosure)

All companies listed on the SET and the Market for Alternative Investment (mai) must include sustainability-related information in their annual Form 56-1 One Report. This filing integrates ESG disclosures alongside traditional financial information, and requires disclosure of material policies, risks, management approaches, and performance results relevant to the business.

Voluntary participation (performance programs)

Initiatives such as the SET ESG Rating and Thailand Sustainability Investment (THSI) are optional. Companies that participate are assessed against defined performance criteria, but these programs do not replace or modify the mandatory One Report disclosure obligations.

Private companies and unlisted entities

Private companies are not subject to SET reporting rules, but they may choose to adopt SET’s reporting guidance or global frameworks such as the GRI, TCFD, or ISSB to enhance transparency or appeal to investors, customers, and lenders. Legal obligations beyond the SET still apply to private companies and may overlap with ESG topics.

Is sustainability reporting mandatory for all SET-listed companies?

Yes, sustainability disclosure is mandatory through the 56-1 One Report for all listed companies. Performance ratings such as the SET ESG Rating remains voluntary and are separate from regulatory reporting.

Why is SET Sustainability Framework important for listed companies?

The framework:

Enhances investor confidence and market credibility by making ESG information transparent and comparable
Helps companies manage ESG risks and seize opportunities that affect long-term value
Supports alignment with international sustainability practices, increasing Thailand’s attractiveness to global capital
Encourages continuous improvement across environmental, social, and governance areas, not just annual reporting

What are the key ESG disclosure requirements under SET Sustainability Framework?

The framework supports the ESG content disclosed in the Form 56-1 One Report. Companies are expected to report material, decision-relevant information in areas such as:

Governance and oversight
- Governance policies and structures relevant to ESG
- Board and risk management processes covering environmental and social risks
Environmental information
- Management approaches and impacts related to climate, resource use, pollution, and natural capital
- Relevant performance indicators, such as emissions, energy, water, climate-risk exposure
Social information
- Workforce practices, safety, human rights, supply chain, stakeholder, and community impacts
- Associated performance results
Materiality, metrics and progress
- How material ESG issues influence strategy and value creation
- Metrics, targets, and year-on-year performance with appropriate context
Alignment with global frameworks
- Optional use of standards such as the Global Reporting Initiative (GRI)
- Climate-related frameworks like the TCFD or ISSB Sustainability Standards where applicable to enhance comparability and investor usability

The SET Sustainability Reporting Guide provides supporting metrics and checklists to help companies disclose these topics consistently within the One Report structure

What is the scope of SET Sustainability?

The SET Sustainability framework applies to:

All SET and mai listed entities through mandatory disclosure requirements
Voluntary ESG performance programs that companies may join, such as SET ESG Rating and ESG Indices
Ecosystem tools and initiatives, including data platforms, reporting guides, and capacity-building programs that support quality ESG integration and reporting
