Why ESG Investors Should Look Beyond the Obvious Choices

Companies that are on course to overcome ESG controversies deserve closer attention from investors.

Sustainable equity funds tend to shy away from sectors and companies that are deemed to be controversial. Yet by targeting challenged sectors with room for improvement and overlooked companies that enable positive change, we think investors can access more diverse sources of return potential in portfolios focused on environmental, social and governance (ESG) issues.

For many ESG-focused investors, buying shares of companies that are good actors seems a natural choice. After all, shouldn’t we reward companies with low CO2 emissions, positive social policies and good governance? By doing so, bad actors will be incentivized to behave better.

When executed properly and backed by a coherent engagement agenda, this strategy is an effective way to support ESG goals and source equity returns. But there’s another road to ESG investing that is much less travelled—and offers access to an entirely different set of companies.

ESG Upgrades Help Support Outperformance

Despite conventional wisdom, we think companies with lower ESG ratings deserve closer attention. That’s because many companies with high ESG ratings can’t realistically improve much more, while lower-rated companies have more room for improvement, which can also support returns.

Our research shows that shares of companies receiving an ESG rating upgrade outperformed the MSCI All Country World Index (ACWI) by 0.36% over the subsequent 12-month period, while those that were downgraded underperformed by 1.33% (Display). In other words, companies likely to see an increase to their ESG rating can be a source of return potential—for investors who can find them.

Recognition of ESG Improvement Can Help Drive Stock Returns

New academic research supports this approach. Kelly Shue, professor of finance at Yale University, has studied how low-emission “green” firms and high-emission “brown” firms changed their environmental impact given changes in their cost of capital. “What we’ve found is even if it gets easier for these green firms to access capital, their environmental impact barely changes,” Shue said in a Freakonomics Radio podcast entitled “Are ESG Investors Actually Helping the Environment?” “When the cost of capital increases for brown firms, they seem to react by becoming more brown.”

Divesting from brown firms is counterproductive, according to Shue. That’s because a higher cost of capital makes these companies more concerned about short-term survival, so they will be less likely to focus on long-term initiatives to cut emissions. Brown companies often have innovative ideas for reducing emissions—but need capital to implement them.

Which Sectors Reduce Emissions Most?

Not surprisingly, companies with high CO2 emissions are found in sectors such as energy, materials and utilities. Sustainable funds generally avoid these sectors (Display), even though the companies at the heart of the problem are actually part of the solution, in our view. Materials and utilities companies accounted for 84% of emissions reductions among MSCI ACWI companies from 2016 to 2022.

Active equity investors can help support future improvements. By taking a position in a polluting power generator or a high-CO2-emitting chemicals manufacturer, investors also gain an opportunity to influence management. These engagements can help point an ESG laggard in the right direction, by showing how cleaning up their act can benefit the business—and their shareholders.

To find overlooked ESG opportunities, we think investors should look for two types of companies: those with unrecognized ratings upgrades, and neglected enablers.

Looking Ahead—Not Back

ESG ratings are inherently backward looking. They paint an incomplete picture of a company’s ESG credentials because they don’t tell you how a company might be bettering itself. Using fundamental research and deep industry expertise, active investors can identify companies that are on track to deliver positive change before it is reflected in their ratings.

Diversifying Factor Exposures in ESG-Focused Portfolios

These types of companies can also provide diversification benefits. That’s because many unrecognized improvers and neglected enablers are classified as value stocks, which are underrepresented in sustainable portfolios. Most sustainable and ESG-focused equity funds have a growth-equities tilt. So investors seeking to broaden style diversification in ESG-focused stocks can combine these two approaches and achieve a complementary, more balanced style exposure in their allocations.

Investing in ESG improvers and enablers requires a mindset shift. Simply excluding sectors and companies that produce huge emissions or score low on ESG ratings probably won’t help facilitate the world’s energy transition or other sustainability goals. By developing investment theses that view ESG improvements as central to capturing return potential, investors can find new routes to companies and stocks that can help move the most stubborn needles for a more sustainable future.
