What data do you provide?

ISS ESG’s Environmental and Social QualityScore is a data-driven scoring and screening solution designed to help institutional investors monitor the ESG disclosures of their portfolio companies. Environmental and Social QualityScore provides a measure of corporate disclosure practices and degree of transparency provided to shareholders and other stakeholders using a numeric, decile-based score that indicates a company’s disclosure practices relative to their industry group. Measuring the depth and extent of disclosure of approximately 4,700 companies globally, decile-based scores represent a relative measure based on the raw score calculations of the other companies in their specific industry group. A score of 1 indicates relatively higher quality disclosure and transparency practices, and conversely, a score of 10 indicates relatively lower quality.

Where and how do you source your data?

ISS Environmental and Social QualityScore focuses on a company’s disclosure practices. Data is collected from company publications including mainstream filings, sustainability and corporate social responsibility reports, integrated reports, publicly available company policies and information on company websites. Confirmation of company participation in or formal endorsement of authoritative multi-stakeholder initiatives is collected from websites or member list made available by the relevant initiatives.

Aside from issuer requests for updates, company data is updated annually on a rolling basis, based roughly on the timing of their annual general meeting which is the typical time of filing annual reports and sustainability reports, issuing updates on company policies and introducing other significant changes to corporate disclosures.
