Every ESG rating a Thai company faces, compared.
FTSE Russell, S&P Global’s CSA, MSCI, Sustainalytics, CDP, EcoVadis — a SET-listed company can be scored by all six, on different scales, by different people, for different audiences. This is the one place they are laid out side by side, with the through-line that decides most of them: five of the six score you from whatever you have already published.
- 01FTSE Russell — 0–5.0
- 02S&P Global CSA / Best-in-Class
- 03MSCI — AAA to CCC
- 04Sustainalytics — risk score
- 05CDP — A to D−
- 06EcoVadis — 0–100 + medals
Six systems. One evidence base.
A single SET-listed company can face all six of these at once. They use different scales and different mechanics — but most draw on the same public disclosure, and only one of them publishes a language policy at all. This is how they compare, as of 2026.
| Rating system | Scale | Best result | How you’re assessed | Who drives it |
|---|---|---|---|---|
| FTSE Russell | 0 – 5.0 | 5.0 | Unsolicited — your public disclosure, no questionnaire | Index inclusion (SET → FTSE, 2026) · investors |
| S&P Global CSA / Best-in-Class | 0 – 100 | Top 1% · index | Questionnaire — participate, or be scored on public data | Investors · index inclusion · Yearbook |
| MSCI ESG | AAA – CCC | AAA (Leader) | Unsolicited — public data, 33 industry key issues | Investors · index screening |
| Sustainalytics | 0 – 100 (lower better) | Negligible (<10) | Unsolicited — public data, unmanaged-risk model | Investors · Morningstar funds |
| CDP | A – D− | A (Leadership) | Questionnaire you submit, request-driven | Investors + customers (supply chain) |
| EcoVadis | 0 – 100 + medals | Platinum (top 1%) | Evidence you upload, customer-requested | Customers · procurement |
Here you control the input — so evidence quality and framing decide the score.
- EcoVadis — upload evidence; customer-requested.
- CDP — complete the questionnaire; investor/customer-requested.
- S&P Global CSA — participate to submit evidence public-only scoring never sees.
Built from public data without asking — so the lever is what you disclose and how clearly.
- FTSE Russell — scores your public disclosure; no questionnaire.
- MSCI — public data, 33 key issues; correct it via the issuer portal.
- Sustainalytics — public data, unmanaged-risk; a two-week draft window.
Different scales, one source of truth.
Read across the table and a pattern appears: the ratings differ in mechanics but converge on the same raw material — your disclosed ESG evidence. Manage that once, coherently, and you move all six at the same time.
Submit vs unsolicited
EcoVadis, CDP and the CSA take a submission you control; FTSE, MSCI and Sustainalytics rate you anyway from public data. The strategy differs — the evidence base does not.
One states a language
S&P Global’s CSA is the only one of the six with a published language policy — English is its official language, and it disclaims accuracy on any automated translation it applies. FTSE lists six research languages in a FAQ, and Thai is not among them, though its scoring methodology says nothing about language. The rest are silent.
Reconcile, don’t repeat
The same target or policy is scored six ways. We keep one coherent set of ESG facts so your CDP, FTSE and EcoVadis answers never contradict each other.
Pick your battles
Not every rating matters equally to every company. We map which ones your investors and customers actually use, and sequence the work accordingly.
Carbon underneath
Climate scores across all six lean on measured Scope 1·2·3 numbers. Our TGO CFO/CFP bench produces the inventory the ratings read.
Two mechanics. And what each one publishes about language.
The ratings split on one thing before anything else: whether they come to you with a questionnaire, or score whatever you have already published. Everything below is quoted from the raters’ own current documents — including where they say nothing at all.
One place English is simply the law. Not a rating at all: under the EU Carbon Border Adjustment Mechanism, an operator’s emissions report “shall be submitted in English.” That is the only hard legal English-language requirement any Thai exporter faces — and it sits in a regulation, not a methodology.
Commission Implementing Regulation (EU) 2025/2547, Article 10(4)
And the fact that cuts the other way. Thai companies are scoring well and improving fast. In the 2025 round the Stock Exchange of Thailand published an average FTSE Russell ESG Score of 3.6 out of 5.0 across 222 Thai listed companies, with Governance averaging 4.5 and Environment lowest at 3.0. We publish that because it is true and because you would find it in one search — the case for a strong English edition is about reducing avoidable risk, not about Thai companies being penalised.

Proof, not adjectives.
Othello is a Bangkok bilingual technical-translation and ESG-advisory firm founded in 2020 on US CDC and State Department work. The disclosure this page describes is delivered by the same in-house, ISO 17100-aligned bench — under NDA from the first email.
FTSE Russell ESG Score 4.0/5.0
The first FTSE Russell ESG result after the SET ESG transition announcement — secured under LSEG global methodology for a SET-listed healthcare operator. Our bench led the climate disclosure, GHG inventory, framework alignment and submission. The same methodology stack drives the 2026 disclosure cycle across every SET sector.
What boards ask first.
The questions Thai listed companies raise when the rating requests start arriving — click any to expand.
01Which ESG rating matters most for a Thai company?+
It depends on your investors and customers. For SET-listed companies, FTSE Russell is pivotal because of the 2026 transition; exporters and suppliers are most often pushed into EcoVadis and CDP by customers; index-focused issuers prioritise the S&P Global CSA. MSCI and Sustainalytics affect you regardless, because they rate from public data. We map your actual exposure rather than chasing all six equally.
02Do I have to do all of them?+
No. Some are unsolicited (FTSE, MSCI, Sustainalytics) and some are requested by specific investors or customers (CDP, EcoVadis, the CSA). We identify which ones your stakeholders actually use and sequence the work — but because they share an evidence base, improving one usually helps the others.
03What do all six have in common?+
They all reward disclosed and verifiable evidence over intentions, and they all draw heavily on your public reporting and your carbon numbers. That shared foundation is why a single, well-built English disclosure moves several ratings at once.
04Are these the same as a credit rating?+
No. These are sustainability/ESG ratings, produced by specialist providers for investors, customers and index inclusion — separate from credit ratings. Some (like MSCI and Sustainalytics) are unsolicited; others (like CDP and EcoVadis) you actively complete.
05Can you help across all of them?+
Yes — that is the point of the service. We keep one reconciled set of ESG facts and prepare each rating from it: EcoVadis, CDP, S&P Global CSA, MSCI & Sustainalytics and FTSE.
