Sustainability Ratings & Rankings
Easily factor sustainability into your investment decisions by identifying risks, assessing long-term value, meeting regulatory requirements, and seizing new opportunities.
Our Ratings and Rankings—Backed by Research, Analysis and Data
With our holistic datasets, rigorous analytics, and global team of experts, we can help inform your investment decisions by giving you a deeper understanding of your portfolio’s impact across multiple sustainability dimensions.
We evaluate companies across their corporate value chain and assign them a Performance Scale rating from D- to A+ based on their sustainability performance on an absolute best-in-class basis. Our comprehensive methodology is guided by established international guidelines.
We evaluate the world’s largest issuers of sovereign bonds across over 100 social, environmental and governance criteria. See ratings from the European Union (EU), the Organisation for Economic Co-operation and Development (OECD) and Brasil, Russia, India, China, South Africa, Saudi Arabia, Egypt, United Arab Emirates, Ethiopia, Indonesia, and Iran (BRICS), as well as other important sovereign issuers from Asia and South America.
Using our Corporate and Sovereign Ratings, we evaluate and benchmark the performance of equity and bond funds globally—helping you identify investments that align to your objectives and values.
We evaluate hundreds of data points across regions and industries to give you a comprehensive assessment of the climate impact and risk exposure of global labeled debt. It gives you an easy way to assess whether your Green, Social, Sustainability Transition, and Sustainability-linked fixed income securities are compliant with international standards.
Our Rating Methodology is Robust and Transparent
We firmly believe in the value of transparency. That’s why we make the methodologies we use to evaluate sustainability performance available to the public.
QualityScores
Our QualityScores go beyond what’s publicly available to help you assess the risks and opportunities of companies and municipal bonds in your portfolio. Their broad coverage allows you to get a complete picture of performance.
We examine 8,000 companies’ public reports across 25 industry groups to identify key disclosures, omissions and other details to determine the quality of their disclosure practices—helping you identify environmental and social risks beyond what a company makes publicly available. Companies are only compared to peers in their industry group, with an annual methodology review that ensures our scores remain aligned with evolving disclosure standards.
Drawing on our global coverage, we deliver a scoring and screening solution that supports comprehensive, high‑quality reviews of corporate governance across four key areas: Audit & Risk Oversight, Board Structure, Compensation, and Shareholder Rights.
With an unmatched level of transparency, we give you access to sustainability rankings, scores and underlying data for municipal bonds in all 50 states at the GEO.id level, as well as the CUSIP6 level for issuers.

Our intuitive, easy-to-use tool gives you a straightforward assessment of private companies’ environmental, social and governance risks and opportunities.
