MSCI ESG Ratings

MSCI ESG Ratings are designed to help institutional investors understand ESG-driven risk and opportunities and integrate these factors into their portfolio construction and management process.

Our global team of over 170 research analysts rates over 6,400 companies (11,800 total issuers including subsidiaries) and more than 400,000 fixed income securities globally. The team assesses thousands of data points across 37 ESG issues, focusing on the intersection between a company’s core business and the industry issues that can create significant financial risks and opportunities for the company. Companies are rated on a AAA-CCC scale relative to the standards and performance of their industry peers.

To maintain our leading edge in research methodology, MSCI ESG Research periodically seeks feedback and opinions from external experts on specific ESG issue areas through the MSCI ESG Research Thought Leader Council.

MSCI ESG Indexes

Our ESG Research ratings and data are used in the construction of the MSCI ESG Indexes. Our suite of over 900 equity and fixed income ESG Indexes designed to represent the performance of some of the most prevalent ESG strategies can be used to help institutional investors more effectively benchmark ESG investment performance, issue index-based investment products, as well as manage, measure and report on ESG mandates.

MSCI ESG Governance Metrics

As long-term institutional investors, asset owners often look to managers to more fully assess governance-related risks. Following MSCI ESG Research's acquisition of corporate governance research and analysis provider GMI Ratings in August 2014, governance expertise is now integrated within MSCI ESG Research’s global team. Our analysts provide critical insight into timely corporate events, including analysis of potential governance concerns associated with high profile IPOs like Facebook and Alibaba and controversies such as Volkswagen and Valeant Pharmaceuticals

MSCI ESG Research’s unique corporate governance research process examines company events and corporate behavior as well as governance structure, providing data and analysis through MSCI ESG Governance Metrics, specifically:

  • 96 governance metrics organized into four pillars (Board, Pay, Ownership and Control, Accounting)
  • Coverage of 7,000+ global companies
  • Comprehensive data on 65,000 corporate directors and officers
  • 13+ years of shareholder proposals and meeting results data

Corporate governance can help identify risk associated with lax oversight, excessive pay, corporate misconduct and accounting irregularities. Through a combination of data, analysis, ratings and other tools, Governance Metrics is designed to enable institutional investors to both conduct bottom-up research on individual securities and to assess governance risk across an entire portfolio.


MSCI ESG Controversies is designed to provide timely and consistent assessments of ESG controversies involving publicly traded companies and fixed income issuers.

The tool monitors company involvement in notable ESG controversies related to the company’s operations and/or products, possible breaches of international norms and principles such as the UN Global Compact, and performance with respect to these norms and principles. Each Controversy is attributed a 0-10 score and a flag color depending on the severity of its environmental, social or governance impact.

MSCI ESG Controversies covers approximately 8,800 companies in the MSCI ACWI Investable Market Index, in addition to approximately 95% (by market value) of a leading fixed income index.


The MSCI ESG AGR model is designed to help institutional investors, insurers and other financial institutions understand and manage accounting risk. With coverage for over 29,000 companies worldwide, AGR ratings help identify potential accounting irregularities that may go undetected by traditional research methods.

  • MSCI ESG AGR provides a comprehensive measure of corporate integrity, based on an extensive statistical evaluation of both accounting and non-accounting metrics which have been associated with lack of integrity of a firm’s financial reporting and corporate governance. These metrics can identify patterns that have been found among companies that have manipulated their financial reporting in the past. Metrics that are outliers relative to peers or whose change over time is extreme are flagged as concerns
  • Updated quarterly, the AGR score ranges in percentiles from 1-100, with lower values representing greater risks
MSCI ESG Screening and Carbon Tools

Many asset owners and managers are subject to guidelines that restrict investments or place thresholds on companies involved in certain lines of business, including federal and state sanctions on companies with operations in countries such as Sudan and Iran. Our screening research enables institutional investors to satisfy client investment guidelines, implement client mandates, and manage potential ESG portfolio risks.

We also offer an extensive suite of low carbon tools and solutions designed to help institutional investors better understand portfolio exposure to carbon asset risk and implement fossil fuel exclusion, low carbon or thematic investment strategies.

Our ESG Research products and services are available on our integrated online platform, MSCI ESG Manager, and are also available on MSCI’s BarraOne and Barra Portfolio Manager platforms, as well as in FactSet and StyleResearch.


Institutional investors are increasingly looking for ways to steer capital towards companies and projects that provide solutions to major social and environmental challenges, but achieving impact at scale can be a challenging proposition. The United Nations Sustainable Development Goals (SDGs) provide a useful foundation for scalable impact, representing a broad consensus of global stakeholders around 17 ambitious development goals.

MSCI ESG Research has developed a new framework designed to allow institutional investors to measure their current exposure to listed companies providing sustainable impact solutions. MSCI ESG Sustainable Impact Metrics covers over 2,500 companies for social impact themes and over 8,500 companies for environmental impact themes. The MSCI ACWI Sustainable Impact Index, which leverages the data, is designed to target companies with high net exposure to sustainable impact themes while meeting minimum ESG standards.
