What data do you provide?

ISS ESG’s Corporate Ratings provide a detailed assessment of a company’s ESG performance. The areas and indicators assessed are influenced by several factors such as international norms and conventions, social debate, regulatory changes and technological progress.

In order to analyse a company’s management of ESG issues within its core business, ISS ESG’s sector specialists select a set of criteria from its pool of over 800 indicators. The social and environmental dimensions of the rating are weighted according to ISS ESG’s industry classification system, which is based on the environmental and social impact of particular sectors.  The Corporate Ratings universe covers issuers in approximately 60 sectors.

Where and how do you source your data?

ISS ESG’s Corporate Ratings data is primarily sourced from publicly available information, including a company’s own disclosure and reporting, proxy statements, reputable news, governmental and international institutions, recognised international or local non-governmental organizations, and non-biased subscription databases such as the CDP. 

During the rating process, considerable importance is attached to the dialogue with the company under evaluation. Every other year, ISS ESG provides companies with the opportunity to comment on and add to the provisional findings by submitting a draft rating report to the company for revision. After the period of consultation, the report is finalized, integrating the comments and additions that are deemed appropriate by the analyst in charge of the rating.
