ESG CORPORATE RATING
Transparent Methodology
At ISS STOXX, we firmly believe in the value of transparency as a catalyst for selecting the sustainability solutions best suited to realizing sustainable investment objectives. As such, we are making our comprehensive Methodology and Research Process Document, an overview of the approach to evaluating the performance of companies through the ESG Corporate Rating, as well as the results of our latest ESG Corporate Rating Survey publicly available.
The methodology document provides detailed information on our approach to evaluating the sustainability performance of companies, and supports investor clients’ reporting needs in specific jurisdictions, as well as fulfilling stakeholder expectations with regard to (public) methodology transparency. In addition to exploring fundamental questions such as methodological foundations and materiality, the document comprehensively covers the rating methodology and process, including:
- Industry Classification
- Rating Structure, Weightings, and Key Issues
- Assessment Rules
- Rating Outputs and Signals
- Rating Process
- Quality Assurance

Holistic Approach to Assessing Sustainability Through a Double-materiality Lens
Building on extensive experience and expertise
in the field of sustainability
We have developed a holistic and
forward-looking concept of materiality
that focuses on long-term value creation.
Our performance analysis assesses risks and impacts related to all relevant stakeholders such as:
EMPLOYEES
SUPPLIERS
CUSTOMERS
COMMUNITIES
ECOSYSTEMS

PRIME STATUS
Awarded to companies with an ESG performance above the sector-specific Prime threshold, which means that they fulfil ambitious absolute performance requirements.
ESG CORPORATE RATING PERFORMANCE SCALE
Companies are rated, from D- to A+, on their sustainability performance on an absolute best-in-class basis.
Introducing the Financial and ESGF (ESG + Financial) Ratings
The Financial Rating is a standalone rating that can be used on its own to assess companies’ financial performance. The ESGF Rating combines the Financial Rating and ESG Rating to provide a holistic assessment of companies’ performance. Both ratings and the underlying data factors leverage data from ISS EVA, an established standard in measuring, analyzing, projecting, valuing, and discounting a firm’s underlying economic profit rather than its accounting profit.
High-level and detailed company reports are available for download on our proprietary DataDesk platform. Recent enhancements to the reports include:
- New design that presents key outputs and signals in an easily digestible manner
- Further insights related to Key Issues (Key Issue detail, Key Issue materiality graph)
- Introduction of new financial (EVA Margin), SDG-, and climate-related scores and metrics
- Additional rating performance summary pages
- Integration of a year-on-year trend factor at the indicator level
