Watch-outs

• High cost for enterprise ESG data: ISS ESG subscriptions are priced for institutional investors with significant compliance requirements — smaller asset managers and non-financial companies find the cost disproportionate for their ESG reporting needs.
• ESG rating methodologies are contested: ISS ESG ratings reflect ISS's specific methodology — ESG ratings from different providers frequently diverge, and institutional investors must understand methodology choices rather than treating any single provider's scores as objective ground truth.
• Competes with MSCI ESG and Sustainalytics: MSCI ESG Research and Sustainalytics (Morningstar) compete directly with ISS ESG for institutional ESG data — investors typically evaluate multiple ESG data providers based on methodology alignment with their investment philosophy.
