While the mainstreaming of forms of sustainable finance is a welcome development, the terminology and practices associated with ESG investing vary considerably. One reason for this is that ESG investing has evolved from socially responsible investment philosophies into a distinct form of responsible investing. While earlier approaches used exclusionary screening and value judgments to shape their investment decisions, ESG investing has been spurred by shifts in demand from across the finance ecosystem, driven by both the search for better long-term financial value, and a pursuit of better alignment with values. This report provides an overview of concepts, assessments, and conducts quantitative analysis to shed light on both the progress and challenges with respect to the current state of ESG investing. It highlights the wide variety of metrics, methodologies, and approaches that, while valid, contribute to disparate outcomes, adding to a range of ESG investment practices that, in aggregate, arrive at an industry consensus on the performance of high-ESG portfolios, which may remain open to interpretation. The key findings of our analysis illustrate that ESG ratings vary strongly depending on the provider chosen, which can occur for a number of reasons, such as different frameworks, measures, key indicators and metrics, data use, qualitative judgement, and weighting of subcategories. Moreover, returns have shown mixed results over the past decade, raising questions as to the true extent to which ESG drives performance. This lack of comparability of ESG metrics, ratings, and investing approaches makes it difficult for investors to draw the line between managing material ESG risks within their investment mandates, and pursuing ESG outcomes that might require a trade-off in financial performance. Despite these shortcomings, ESG scoring and reporting has the potential to unlock a significant amount of information on the management and resilience of companies when pursuing long-term value creation. It could also represent an important market based mechanism to help investors better align their portfolios with environmental and social criteria that align with sustainable development. Yet, progress to strengthen the meaningfulness of ESG Investing calls for greater efforts toward transparency, consistency of metrics, comparability of ratings methodologies, and alignment with financial materiality. Lastly, notwithstanding efforts by regulators, standard setting bodies, and private sector participants in different jurisdictions and regions, global guidance may be needed to ensure market efficiency, resilience and integrity. This report has been prepared to support the work of the OECD Committee on Financial Markets. It is part of a broader body of work to monitor developments in ESG rating and investing. The note and accompanying analysis has been prepared by Riccardo Boffo and Robert Patalano from the OECD Directorate for Financial and Enterprise Affairs. It has benefited from comments by members of the OECD Committee on Financial Markets, OECD colleagues Mathilde Mesnard, Geraldine Ang and Catriona Marshall, and has been prepared for publication by Pamela Duffin, Edward Smiley and Karen Castillo.

The growing investor interest in ESG factors reflects the view that environmental, social and corporate governance issues – including risks and opportunities -- can affect the long-term performance of issuers and should therefore be given appropriate consideration in investment decisions. While definitions differ regarding the form of consideration of ESG risks, broadly speaking ESG investing is an approach that seeks to incorporate environmental, social and governance factors into asset allocation and risk decisions, so as to generate sustainable, long-term financial returns.2 Thus, the extent to which the ESG approach incorporates forward-looking financially-material information into expectations of returns and risks, and the extent to which it can help generate superior long-term returns, is the focus of this report.
