ESG Analyst

An ESG Analyst researches and evaluates companies' environmental, social, and governance performance to support investment decision-making, stewardship activities, or corporate ESG strategy. In an investor-facing context, the role involves assessing companies against ESG criteria, engaging with company management on ESG practices, contributing to portfolio-level ESG reporting, and supporting the integration of ESG factors into investment analysis. In a corporate context, the role involves monitoring peer ESG performance, responding to investor ESG queries, managing relationships with ESG ratings agencies, and supporting the development and disclosure of the organisation's ESG strategy. Day-to-day work involves data gathering from ESG databases and company disclosures, quantitative analysis of ESG metrics, writing research notes or disclosure responses, and staying current with evolving regulatory requirements and investor expectations. ESG Analyst roles exist primarily in asset management, investment banking, pension funds, ESG ratings agencies, and at large listed companies managing their own ESG function. The profession has grown dramatically since 2020 as ESG integration moved from a niche practice to a mainstream expectation among institutional investors. The UK is one of the world's leading ESG investment markets, driven by the FCA's ESG disclosure requirements for asset managers, the pension fund trustee duties under the Pension Schemes Act, and the TCFD mandatory reporting regime. Analysts who combine investment analysis skills with deep ESG framework knowledge are among the most sought-after professionals in the asset management sector.

History and context

ESG investing has roots in socially responsible investing (SRI) from the 1970s and 1980s, but the modern ESG framework emerged from a 2004 UN report — "Who Cares Wins" — that argued integrating ESG factors into investment analysis leads to better long-term outcomes. The concept was formalised in the UN Principles for Responsible Investment (PRI), launched in 2006, which now has signatories managing over $120 trillion in assets. In the UK, the Stewardship Code — updated in 2020 — raised expectations for how asset managers engage with investee companies on ESG and systemic risk, and the FCA's Sustainable Finance Disclosure Regulation and SFDR alignment have created new product-level disclosure requirements. The field is maturing rapidly and becoming more technically rigorous. The proliferation of ESG data providers — MSCI, Sustainalytics, CDP, Bloomberg ESG, Refinitiv — has created both more data and more analytical complexity as providers use different methodologies and often disagree significantly on company-level ratings. The ISSB's IFRS S1 and S2 standards, and the EU's CSRD, are driving convergence toward comparable, auditable sustainability disclosures that will eventually make ESG data more like financial data in reliability and comparability. UK ESG analysts who can navigate this evolving landscape — understanding the strengths and limitations of different data sources, engaging constructively with companies on disclosure quality, and applying both quantitative and qualitative analysis — are the most valued in the market.

Question 2 · #2

TechnicalMedium

What are the main ESG rating agencies and how do their methodologies differ?

technicalesg-analyst

Why they ask

ESG ratings are the primary data infrastructure for the industry. Understanding the major providers and their methodological differences is a baseline expectation — an analyst who cannot distinguish MSCI from Sustainalytics has not done minimum preparation.

What they want

A credible overview of the major ESG data providers, the key methodological differences between them, and awareness of the research showing significant divergence between providers.

How to structure your answer

Name the major providers — MSCI ESG Research, Sustainalytics, Bloomberg ESG, CDP, Refinitiv
Describe key methodological differences — industry adjustment, data sources, weighting
Reference the divergence problem — providers frequently disagree significantly
Note the implications for analysis — ratings should be used as a starting point, not a definitive answer

Sample answer

The major ESG data and ratings providers include MSCI ESG Research, Sustainalytics, Bloomberg ESG, Refinitiv, and CDP — each with a distinct methodology and coverage focus. MSCI uses an industry-adjusted approach, rating companies relative to peers in their sector rather than on an absolute scale, which means a mining company can receive a high MSCI ESG rating even if its absolute ESG impact is significant. Sustainalytics focuses on ESG risk — specifically the risk that unmanaged ESG issues could have a material impact on enterprise value — and reports an unmanaged risk score rather than a relative grade. CDP focuses specifically on climate, water, and forests disclosure quality, running annual disclosure processes and scoring companies on the completeness and quality of their environmental disclosures. Bloomberg ESG aggregates ESG data from company disclosures and third-party sources into standardised metrics without applying the same judgmental rating overlay as MSCI or Sustainalytics. A key insight about ESG ratings is that they diverge significantly — academic research has shown correlations between major providers of only 0.4 to 0.7, meaning two providers can assess the same company's ESG performance very differently. This divergence reflects genuine differences in what is being measured, how data gaps are filled, and how metrics are weighted rather than simple measurement error. For an ESG analyst, the practical implication is that ratings should be used as an input to analysis, not a substitute for it — understanding what drives a particular rating, where providers disagree and why, is where analytical value is added.

Common mistakes

Naming providers without describing their methodological differences — lists without analysis are not sufficient
Not mentioning the divergence problem — it is one of the most important and well-documented issues in the field
Treating ESG ratings as objective assessments rather than methodologically-determined outputs with significant limitations

Bonus tips

Reference the Berg, Kölbel, and Rigobon 2022 paper on ESG ratings divergence if you have read it — it is well-known in the field
Mention that CDP scores are specifically for environmental disclosure quality and are often used by procurement teams and investors separately from the broader ratings
Note that some asset managers build their own proprietary ESG scores rather than relying on third-party ratings — it signals awareness that the field is more nuanced than buying a data subscription
