Inconsistencies in ESG Metrics

With sustainable and impact investing assets accounting for a fourth of the total U.S. net flows in 2020, it is clear that environmental, social, and governance (ESG) investing continues to grow in popularity. Despite this rapid interest in ESG investing, the data remains inconsistent, and investors are wondering what metrics to use to measure ESG results. In this blog, we detail the current landscape of ESG metrics, explain how we at Wealthspire evaluate funds in this space, and provide resources that can be used by the everyday investor.

What is Impact Investing?

Aligning investment portfolios with personal values can come in many different forms (and many different definitions depending on who you ask). While ESG, impact investing, and socially responsible investing (SRI) are often used interchangeably, there are some subtle differences, which you can learn more about here.

At a high level, impact investing reflects the values of the investor and their specific social and financial goals through direct investment and engagement with companies.

How is ESG Investment Measured?

We consider several metrics to objectively measure performance and identify risk. For example, ESG ratings are designed to measure an individual company’s resilience to environmental, social, and governance (ESG) risks. These can help investors identify industry leaders and underperformers according to their exposure to ESG risk and how well they manage the risks relative to their peers. Different providers of ESG ratings include MSCI, Sustainalytics, and S&P Global.

Why Are Ratings Not the Same?

The challenge is that there is no consistent approach to these ratings. The methodology, scope, and coverage can vary greatly among providers, each with their own subjectivity and their own mix of “art” and “science”. They can use different metrics or weigh different issues such that each provider may evaluate the same company differently due to a lack of standardization. In addition, ESG ratings data can be deficient due to a lack of coverage or a dependence on self-reporting.

What’s an Example of This?

Clients have commonly asked us if Tesla is an ESG company, and the answer is – it depends on who is asking. Here’s why: Tesla is a good illustration of the disparity of ratings among ESG data providers. While some services give Tesla high ESG scores based on its environmental metrics, others rate it poorly based on its governance.

Tesla has received an A rating from MSCI, a B- rating from S&P Global and a high-risk rating from Sustainalytics, below that of traditional automaker General Motors.

How Are These Metrics Evolving?

As the industry evolves, there is a growing focus on standardization, a trend we expect to continue. We applaud efforts by the Sustainability Accounting Standards Board (SASB), an independent organization that sets standards to guide the disclosure of financially material sustainability information by companies to their investors. Its standards identify the subset of ESG issues most relevant to financial performance in 77 different industries. Beyond helping publicly traded companies manage and measure ESG factors, SASB standards can also help individual investors by providing them with comparable, standardized data to inform their investing decisions.

How Does Wealthspire Evaluate ESG Metrics?

The goal for us at Wealthspire is to identify funds and index providers that lean on multiple sources for ESG ranking and scoring, with a greater focus on materiality.

  • Materiality: The carbon footprint of an oil company is very different than that of a life insurer, and materiality helps identify those nuances
  • Engagement: We look for funds that can demonstrate not only how/if they incorporate screens, but a pragmatic approach toward engagement (shareholder activism/proxy voting)
  • Leverage Separately Managed Accounts (SMA): We work with managers who can tailor portfolios to our client’s specific impact goals

Where to Find These Metrics

In addition to the due diligence of our internal Impact Investing Committee at Wealthspire, we evaluate stocks and funds based on information from multiple providers. Here are a few free resources we find helpful:

What’s Important is What Matters to You

We believe what matters most are the values of the investor. As each investor has unique values and goals, no one metric will determine if an investment is right for them. Our holistic approach to impact investing looks to understand the needs of our clients and use impact investing as a decision-making framework applied across a client’s entire portfolio.
