Entering its 28th year, the 100 Best Corporate Citizens ranks the largest publicly-traded companies in the United States based on their non-financial disclosures and how they impact communities, workers and the environment.
3BL updates the 100 Best Corporate Citizens methodology each year in response to the latest developments in corporate sustainability, feedback from corporate and NGO stakeholders, and guidance from our data partners at ISS-Corporate.
The updated methodology for 2026 is now available, including changes from 2025, all factors used to determine the ranking, and an overview of how the ranking is processed.
Russell 1,000 companies in scope for the research can validate the data and information used to score them through ISS-Corporate’s Compass data verification portal, accessible at no cost.
In the methodology, you’ll notice each 100 Best factor is assigned an ID number, which corresponds to the factor ID numbers used in the Compass portal. Please note factors without ID numbers — marked N/A — are not subject to company verification.
Russell 1,000 companies have until July 16 to verify their data for the 100 Best Corporate Citizens. If you already have access to Compass, sign in here to start verifying your data.
