Thaipat’s Homegrown Second-to-none ESG Rating Unit
Firmly Entering Its 12th Year of ESG Data Products Provider in Thailand
14 January 2026 – Thaipat Institute, through its "Thaipat ESG Rating" unit, reaffirms its commitment to rating organizations with outstanding Environmental, Social, and Governance (ESG) performance. Aiming to elevate sustainability disclosure among Thai businesses—not limited to listed companies—the institute is prepared to expand its ESG assessments to over a thousand Thai enterprises within 2026.
Since Thaipat Institute established the Thaipat ESG Rating unit in 2014, it has pioneered the development of sustainability data for Thai businesses. It was the first in Thailand to initiate ESG ratings for listed companies based on publicly disclosed information, utilizing assessment frameworks and sustainability reporting standards that are internationally recognized.
Thaipat Institute’s ESG ratings are conducted independently as an entity external to the capital market. The assessment process adheres to the principles of the International Capital Market Association (ICMA) Code of Conduct for ESG ratings and data products providers. Thaipat ESG Rating produces results from its annual assessment categorized into the following lists:
ESG100 List: The list of 100 securities recognized for outstanding ESG performance and profitable financial results within the assessment year. Established in 2015, this list caters for investors who prioritize investments in securities that are socially and environmentally responsible with no evidence presents sufficient ground for regulatory enforcement during the assessment year, aligning with sustainable investment goals.
ESG Emerging List: The list comprises securities with proactive ESG initiatives or ongoing activities that drive revenue growth or cost saving, so that they offer promising long-term returns for investors. Launched in 2020, the ESG Emerging List serves as an additional investment universe to the ESG100, based on company ESG initiatives’ potential during the assessment year.
ESG Turnaround List: The list includes securities that have experienced negative earnings or have underperformed the market during the assessment year but show potential for recovery through their core business, supported by ESG factors. Introduced in 2023, this list provides an alternative for sustainable investment beyond the ESG100, capturing return opportunities from securities in a recovery phase.
Notably, The ESG100 list has now established itself as the cornerstone for sustainable investing. The constituents of ESG100 list are used to construct Thaipat ESG Indices based on the liquidity criteria calculated and maintained by S&P Global, a leading global index provider. Since 2018, the indices have been made available to global investors via Bloomberg and Reuters platforms. These indices also serve as benchmarks for asset management companies offering ESG-themed investment products (for more details, visit S&P Dow Jones' Custom Indices).
Thaipat ESG Indices are the only ESG indices in Thailand to employ equal weighted methodology where each constituent in the indices has the same weight, regardless of its market capitalization, to avoid concentrating into a few large securities. By eliminating the market capitalization constraint, the equal weighing scheme gives more exposure to smaller cap securities compared to cap weighting. This will give opportunities to small market cap securities with good ESG taking effect in the indices as well as the large market cap ones.
Furthermore, Thaipat ESG rating results – provided as in-depth, entity-specific ESG Rating Reports – offer participating enterprises valuable insights into their annual ESG performance. This enables them to address operational gaps in line with internationally accepted ESG indicators and serve as input data for continuously improving company ESG performance and disclosures.
Currently, the Thaipat ESG rating data covers 953 entities (as of year-end 2025), including listed companies, funds, private companies, and other enterprises. It is anticipated that this number will surpass 1,000 in 2026.
Note: The ESG100 list and other information compiled by Thaipat Institute are provided for informational purposes only. None of the information constitutes an investment advice or an offer to sell, or a solicitation of an offer to buy, any securities.
