The ISS ESG Corporate Rating content set provides investors with highly relevant, material, and forward-looking environmental, social and governance (ESG) data and performance assessments. The methodology has been consistently updated for more than 25 years, delivering high-quality and in-depth research on companies’ sustainability performances.

The rating grasps ESG risks, opportunities, and impacts along the entire corporate value chain, including a dedicated SDG-based component measuring the positive and negative impact of products and services. Additionally, it monitors and integrates the existence and severity of controversies and violations of global norms in the topic-specific and overall assessment.

“Prime” status is granted to industry leaders who fulfill demanding performance expectations. These companies are well-positioned to adequately manage key ESG risks associated with their specific business model and, on the other hand, capitalize on opportunities offered by transformations towards sustainable development.

ISS ESG Corporate Rating supports strategies aligned to several regulations and guidelines:

  • UN Global Compact
  • UN Sustainable Development Goals
  • International Labor Organization
  • OECD Guidelines for Multinational Enterprises
  • UN Principles for Responsible Investment
  • EU Sustainable Finance Regulation

Data Methodology

The ISS ESG Corporate Rating methodology was originally developed by Institutional Shareholder Services Germany (formerly Oekom Research) and has been consistently updated for more than 25 years.

ISS ESG uses a multitude of sources from over 4,500 from selected media outlets and 150+ stakeholder sources. ISS ESG continuously updates based on these sources and any company developments such as mergers, acquisitions, spin-offs, and delistings. Company reports (i.e., annual/CSR reports), company website updates, and specific ESG Impact data (e.g., resource efficiency and emission intensity) are reviewed in depth on an annual basis.

The ISS ESG Corporate Rating product is maintained using a staged process. All ratings are continuously updated to account for material incidents such as significant controversies, accidents, or corporate actions. During the rating process, dialogue with the company under evaluation plays an important role and corporate feedback is actively sourced every second to third year. Rated entities may submit ESG updates at any time.
