A locked glossary beats a per-translator guess.

This lexicon is the public tip of the termbase we lock into every bilingual ESG report — so the same concept reads the same way across your 56-1, your annual report and your investor English.

Why a bilingual ESG lexicon decides disclosure quality

Every Thai listed company now writes sustainability disclosure twice — the 56-1 One Report filed to the SEC in Thai, and the English edition that FTSE Russell, CDP and international investors actually read and score. When the two versions use drifting terminology — when "การปล่อยก๊าซเรือนกระจกขอบเขตที่ 1" becomes "greenhouse gas release" in one chapter and "Scope 1 emissions" in another — a rater reads inconsistency, and inconsistency reads as risk.

This lexicon locks the vocabulary that matters: the ISSB IFRS S1 and S2 terms Thailand’s TSRS adopts, the GRI and SASB metric names, TGO carbon-footprint terminology, and the SET/SEC filing vocabulary — each with English, Thai script, transliteration and a usage note on where the term belongs in a filing. It is the same terminology base our bench locks before translating an 80–200 page bilingual report under ISO 17100.

Use it when drafting the ESG section of your One Report, reviewing a translated sustainability report before it goes to print, or aligning your IR website’s English with the Thai filing.

Answers

Frequently asked questions

What is the Thai-English ESG Lexicon?
It is a bilingual reference that pairs ESG, climate, and carbon terminology in Thai and English so the same concept is expressed consistently across both languages. Othello maintains it drawing on its linguist-approved terminology and disclosure experience.
Why does consistent ESG terminology matter across Thai and English?
ESG frameworks use precise defined terms, and a loose or inconsistent translation can change technical meaning or confuse readers and rating agencies. A shared lexicon keeps disclosure accurate and comparable across languages and across reporting years.
How can the ESG Lexicon help my reporting team?
The lexicon gives reporting and translation teams an agreed vocabulary so that Thai and English versions of a disclosure align and technical terms are used correctly. This supports the consistency that FTSE, IFRS S2, and GRI readers expect.
