At the intersection of sustainability and strategy, many companies adopt an environmental, social and governance (ESG) strategy. In doing so, they can be strongly influenced by the external focus on third-party ESG metrics, which are framed as a way of measuring a company’s performance in ESG.
ESG strategies, which often aim to improve key metrics in a way that a firm finds acceptable or manageable, have given many businesses a pragmatic start toward becoming more sustainable. However, as a path to a better strategy, they have several drawbacks:
- ESG metrics are immature. Much work remains to be done to make them comparable, rigorous and transparent, especially as individual Environmental, Social and Governance scores are often combined to give a single composite measure.
- Managing to ESG metrics isn’t the best way to deploy sustainability as a driver of competitive advantage and value, or to hasten meaningful improvements in environmental and social outcomes. They can be poor inputs to decision-making.
- External ESG metrics offer an imprecise picture of the past, not a guide to the future. It’s difficult to gain competitive or strategic insight by benchmarking history. Given the significant differences between providers at this early stage of ESG maturity, using third-party metrics is unlikely to lead to the strongest future approaches.
- ESG metrics might identify issues, but they rarely point to solutions that lead to outperformance. Similarly, causal links between improving an ESG score and generating value are unclear — depending on the dataset, they fall between weak and non-existent. Focusing on metrics positions sustainability as a problem to fix, not an important part of a holistic strategy. And, as in any field, benchmarking against other firms is unlikely to identify a path to market-beating performance.
- Company performance, not metrics, enables long-term sustainability improvements. Investors support genuine gains in sustainability but, in the long term, won’t tolerate strategies that do not deliver economic value. They may accept lower short-term performance but only if it is explicitly framed as part of a longer-term improvement strategy. CEOs understand this: firms that communicate and deliver both impact and financial performance secure higher investor support for long-term investments, including those to improve sustainability.
For these reasons, with the way ESG and ESG strategies are framed currently, the evidence for a link between economic value and ESG ratings is modest at best. While ESG metrics are closely observed, financial performance remains much more important in corporate valuations.
Organizations should, of course, take seriously the issues underlying ESG metrics; this is an important contribution to preserving the environment and improving other key dimensions of the working world. But a focus on ESG metrics is unlikely to lead to the best combination of increased value and improved sustainability.
