How does a company like Tesla, which makes electric vehicles, get dropped from the S&P 500 ESG index while Exxon is still there?
Lyon:ESG ratings agenciestypically rate companies against others within their industry, so oil and gas companies are rated separately from automotive companies or technology companies. Exxon stacks up fairly well relative to others in the oil and gas category on many measures. But if you compared Exxon to, say, Apple, Exxon would look terrible on its total greenhouse gas emissions.Tesla may rate well on many environmental factors, but social and governance factors have been dragging the company down.S&P listed allegationsof racial discrimination, poor working conditions at a Tesla factory, and the company’s response to a federal safety investigation as reasons for dropping the company.
The way ESG criteria are measured also carries some biases. For example, the ratings consider a company’s direct greenhouse gas emissionsbut not its Scope 3 emissions– emissions from the use of its products. So Tesla doesn’t get as much credit as it might, and Exxon doesn’t get penalized as much as it might.
What can be done to make ESG investments better reflect investors' expectations?
Lyon: One strategy is for investment firms toinvest in a small number of carefully vetted companiesand then use their influence within those companies to monitor behavior and drive change.
Another is for raters to stop trying to aggregate all of the different measures into a single rating.
Investors concerned about ESG often value different objectives – one investor may really care about human rights in South America while another is focused on climate change. When ESG ratings try to force all of those objectives into a single number, they obscure the fact that there are trade-offs.
ESG could be broken up so ratings instead focused on each piece individually.
Environmental issues tend to have a lot of available data, which make E the easiest category to rate in a consistent way. For example, scientific data is available on the increased health risks a person faces when exposed to benzene. The EPA’sToxic Release Inventoryshowshow much benzenevarious manufacturing facilities release. It’s then possible to create a toxicity-weighted exposure measure for benzene and other toxic chemicals. A similar measure can be created for air pollution.
Social issues and governance issues are much harder to aggregate up into single ratings. Within the G category, for example, how do you aggregate diversity in the board room with whether the CEO personally appointed all the board members? They are capturing fundamentally different things.
The SEC is considering a third strategy:enhancing disclosure requirementsso investors have access to better information about what is in their ESG portfolios. The SECproposed new reporting rulesfor ESG funds and advisors on May 25, 2022, including proposing that some environment-focused funds be required to disclose the greenhouse gas emissions associated with the portfolio.
What else to ESG ratings overlook?
Lyon:ESG ratings often omit important behaviors and choices. One that’s particularly important iscorporate political activity.
A lot of companies like totalk a green game, but investors rarely know what these companies are doing behind the scenes politically. Anecdotally, there is evidence that many are actuallyplaying a fairly dirty game politically. For example, a company might say it supports a carbon tax whiledonating to members of Congressandlobbying groupsthat oppose climate policies.
To me, that’s the most egregious failure in the ESG domain. But we don’t have the data to track this behavior adequately, since Congress has not required disclosure of all types of political spending, especially so-called “dark money” fromsuper PACs.
A few organizations are gathering more detailed information on specific issues.InfluenceMap, for example, invests an enormous amount of time looking at companies’ annual reports, tax filings, press releases, advertisem*nts and any information about lobbying and campaign spending to rate them.It gave ExxonMobil a grade of D-for its political action on climate.
What can investors looking for positive impact do if ESG ratings aren't the answer?
Lyon:Investors can always take a more targeted approach and invest in specific categories that they believe will provide essential solutions for the future. For example, if climate change is their leading concern, that may mean investing in wind and solar power or electric vehicles.
ESG funds often claim that they outperform the market because companies with strong management in environment, social and governance areas tend to be better managed overall. And on average, firmswith higher social performancedo have asomewhat higher financial performance. However, some insiders, likeformer Blackrock sustainable investment head Tariq Fancy, argue that ESG portfolios today aren’t very different from non-ESG portfolios, and often hold almost all the same stocks.
There’s also a larger question in the background of all of this: Is investment pressure really what’s going to drive us toward a more sustainable future?
If you want to make a difference, consider spending time working with activist groups orgroups that support democracy, because without public pressure and democracy, countries aren’t likely to make good environmental decisions.
