Ben Felix - Why ESG Investing May Be Doing More Harm Than Good

Short Summary

Main recommendation: Ben Felix argues that the common approach of ESG investing (environmental, social, and governance screening) probably does far less good for the world than investors assume, and that investors who want a real impact should not rely on it as the solution. He points to evidence that raising the cost of capital for "brown" (high-pollution) firms can make them more polluting rather than greener, while ESG investing shows no clear performance advantage over conventional funds.

Key Points

• Investors respond strongly to simple sustainability labels: after Morningstar introduced its globe ratings in 2016, five-globe funds gained inflows and one-globe funds saw outflows, even though more detailed data was also available.
• The 2019 Journal of Finance study found that investors ignored the detailed percentile and sustainability score data and reacted only to the globe symbol, which they associated with better expected returns and lower risk.
• Across many studies, there is no statistically significant performance difference between ESG and conventional funds, and in theory ESG funds should have lower expected returns.
• The 2023 paper "Counterproductive Sustainable Investing" found that cutting the cost of capital for already-green firms yields only small environmental gains, while raising the cost of capital for brown firms produces large negative environmental changes.
• Green stocks' strong returns from November 2012 through December 2020 are explained by unexpected rises in environmental concern, so they act like a hedge that is expected to underperform going forward.
• The "banner vs. plow" distinction: merely excluding fossil fuel stocks is "banner" investing that does little good, while "plow" investing accepts below-market returns to fund socially beneficial projects.

Details Worth Noting

• Concrete instructions: The transcript gives no step-by-step method for doing ESG investing. The actionable guidance is conditional: if your goal is to hedge ESG risks or feel good about your portfolio, considering ESG characteristics of holdings is a valid reason; if your goal is real-world impact, the speaker suggests that plow-minded investing (accepting below-market expected returns to fund socially beneficial investments, such as community bonds) is the approach that actually does good, while excluding stocks alone is not.
• The 2022 paper "The Impact of Impact Investing" found the effect of divestiture on firms' cost of capital is too small to change corporate investment decisions, though other research suggests sustainability investors have raised the cost of capital for some polluting firms.
• The speaker frames ESG as "extremely important and nothing special," citing the paper 'The End of ESG': it affects long-term shareholder value and social impact but is only one of many intangible assets.
• The speaker cites a former BlackRock sustainable investing CEO comparing feel-good ESG investing to "selling wheatgrass to a cancer patient," noting limited evidence of efficacy and the risk of diverting capital from more effective activities.
• The speaker's own stated position is that the solution to making the world better is not clearly known, but that ESG investing "probably isn't it."

Bottom Line

ESG investing is reasonable for managing risk or aligning a portfolio with personal values, but the transcript's evidence suggests it is a weak tool for changing corporate behavior and should not be assumed to produce meaningful environmental good.
