MSCI ESG Ratings runs an AAA-CCC industry-relative, materiality-weighted scale; Sustainalytics (Morningstar) measures unmanaged risk exposure with a risk rating; S&P Global ESG Score is based on the CSA (Corporate Sustainability Assessment) survey; LSEG Refinitiv ESG produces a quantitative score from disclosed data; ISS ESG combines proxy advisory with ratings; FTSE Russell ESG defines index-inclusion criteria; Bloomberg ESG focuses on disclosure score; RepRisk is an outside-in news/NGO risk screen. On the regulatory side, ISSB IFRS S1/S2 took effect in 2024, CSRD started in the EU, and the US SEC adopted climate-related disclosure rules in 2024. Korea follows a track of KCGS, Sustinvest, and KRX-based mandatory ESG disclosure (large caps from 2026), while Japan has GPIF applying ESG integration across `$1.6T AUM` of five asset classes. This article maps ESG data provider methodologies, SASB-to-ISSB standards, TCFD/CSRD disclosure, Scope 1/2/3, green bonds and SLL, greenwashing enforcement, GPIF and KCGS case studies, and ESG ETFs in one read.

MSCI ESG Ratings는 산업 상대평가와 materiality 가중치를 결합한 AAA-CCC 스케일을 운영하고, Sustainalytics(Morningstar)는 risk rating으로 unmanaged risk exposure를 측정한다. S&P Global ESG Score는 CSA(Corporate Sustainability Assessment) 설문 기반이고, LSEG Refinitiv ESG는 보고 데이터의 정량 점수, ISS ESG는 의결권 자문 결합 모델, FTSE Russell ESG는 인덱스 편입 기준, Bloomberg ESG는 disclosure score, RepRisk는 외부 뉴스/NGO 기반 risk screen이다. 규제 측면에서는 ISSB IFRS S1/S2가 2024년 발효되고 CSRD가 EU에서 시작됐으며, 미국 SEC는 climate-related disclosure 룰을 2024년 채택했다. 한국은 KCGS·서스틴베스트·한국거래소 ESG 공시 의무화(2026 대형사) 트랙으로 가고, 일본은 GPIF가 `$1.6T AUM` 5대 자산 전반에 ESG 통합을 적용한다. 이 글은 ESG 데이터 공급자의 방법론, SASB→ISSB 표준, TCFD/CSRD 공시, Scope 1/2/3, 그린본드·SLL, 그린워싱 단속, GPIF·KCGS 한일 사례, ESG ETF까지 한 호흡으로 정리한다.
