Sustainalytics ESG Risk Rating
The Sustainalytics ESG Risk Rating is Morningstar’s broad-based, flagship ESG risk assessment. It is forward-looking in nature and identifies a company’s financial exposure to material ESG risks that are specific to its industry and that company itself. Sustainalytics then determines how successfully a company has managed those ESG risks. The remaining unmanaged ESG risks form the basis for its ESG Risk Rating, which spans from Negligible to Severe.
ESG Risk Rating Building Blocks
Three considerations form the foundation of Sustainalytics’ ESG Risk Rating: Corporate Governance, Material ESG Issues and Idiosyncratic Issues.
Corporate Governance impacts all companies and is a foundational element of the Sustainalytics framework. It reflects their conviction that poor Corporate Governance poses material risks for companies that can have negative financial consequences.
Material ESG Issues are focused on a topic, or set of related topics, that require a common set of management initiatives or a similar type of oversight. Human Capital issues, for example, revolve around the management of human resources. Business Ethics focuses on the management of general professional ethics from taxation and accounting to anti-competitive practices. Another example of a Material ESG Issue is Emissions, Effluents and Waste which focuses on the management of a company’s impact to air, water and land from their own operations. There are approximately 20 Material ESG Issues identified by Sustainalytics and each is considered, if applicable to a company’s business model, in their ESG Risk Rating.
Idiosyncratic Issues are those additional risks that are considered unpredictable or unexpected. Examples of Idiosyncratic Issues are accounting scandals, bribery scandals, or other “black swan” events.
Identify Manageable vs. Unmanageable Risks to Measure Unmanaged Risk
The ESG Risk Rating is predicated on identifying the level of a company’s unmanaged ESG risk. To that end, Sustainalytics identifies the manageable and unmanageable risks applicable to each company and their respective industry. Of a company’s total ESG risk, some portion simply cannot be addressed by management practices. For example, an oil and gas exploration and production company cannot eliminate the carbon emissions risks associated with its business practices. Those companies can manage other ESG risks such as employee safety and human rights issues, among others.
Once manageable ESG risks are identified, Sustainalytics assesses the extent to which those risks have been managed. The “management gap,” reflecting manageable risks that have not been managed, are combined with unmanageable ESG risks to form a company’s total unmanaged risks which are represented by its ESG Risk Rating.
Measuring Unmanaged ESG Risk

- Starting point is a company´s exposure to material ESG issues
- Some companies have unmanageable risks, e.g. an oil company will always face risks related to carbon until it changess its business model
- Of the manageable risk, a portion is managed through a company´s policies, programs, management systems, etc.; the remainder is considered unmanaged (Management Gap)
- The ESG Risk Rating evaluates unmanaged ESG risk
Absolute Rating System
The ESG Risk Rating is absolute, meaning that a company operating in the energy sector can be compared to a company in the consumer discretionary sector. ESG Risk Ratings place companies in five risk categories ranging from Negligible to Severe. The Morningstar US Sustainability Moat Focus Index will include only those companies with ESG Risk Ratings of Negligible, Low or Medium.

A Sustainable Approach to Moat Investing
Many of the most popular sustainable investment strategies seek to offer broad exposure to market indexes while applying some level of exclusionary or inclusionary ESG screens. This may reduce ESG risk in a portfolio, but does not address other performance drivers. The Morningstar US Sustainability Moat Focus Index’s unique combination of forward-looking equity research and ESG screening offers investors a U.S. equity strategy that seeks to provide investors with attractive risk-adjusted returns while mitigating ESG risks.
