Dow Jones STOXX Sustainability Index

What Is the Dow Jones STOXX Sustainability Index?

The Dow Jones STOXX Sustainability Index was a stock index, first published in 1999, which focused on European companies that score highly on environmental, social, and governance (ESG) ratings. In 2010, Dow Jones terminated its collaboration with STOXX, while continuing to offer ESG-oriented stock indexes under different names.

Today, indexes like the Dow Jones STOXX Sustainability Index have steadily risen in popularity throughout the world, as investors increasingly look to incorporate environmental factors into their decision-making criteria.

Key Takeaways

  • The Dow Jones STOXX Sustainability Index was a stock index offered between 1999 and 2010.
  • It was intended to help investors incorporate ESG factors into their portfolios.
  • Today, there are a variety of stock indexes offered under the Dow Jones Sustainability Index umbrella.

Understanding the Dow Jones STOXX Sustainability Index

The Dow Jones STOXX Sustainability Index resulted from a collaboration between Dow Jones & Company and two Swiss-based firms: STOXX and RobecoSAM. Its purpose was to capture European companies on the leading edge of environmental sustainability practices.

To accomplish this, the administrators assigned a sustainability score to each company based on a comprehensive rating system that examined company actions in regard to corporate governance, environmental impacts, and ongoing research and development (R&D) on environmental issues.

These companies were drawn from an investment universe equal to roughly 90% of the aggregate market capitalization of European-based companies. Of these, the selected invested represented roughly the top 20% of companies, as determined by their sustainability scores.

In this manner, the Dow Jones STOXX Sustainability Index provided a convenient reference point for investors interested in improving the environmental standards of their portfolio, whether by selecting individual stocks from the index, or by constructing investment products such as exchange traded funds (ETFs), which use the index as their benchmark.

In 2010, Dow Jones & Company terminated its partnership with STOXX, while continuing to collaborate with RobecoSAM. Today, there are many indices available that are marketed under the general umbrella of the Dow Jones Sustainability Index family. These include various region- and country-specific indexes for areas such as Korea, Chile, North America, and the Asia-Pacific region.

Real-World Example of the Dow Jones STOXX Sustainability Index

The Dow Jones Sustainability Indexes are updated on an annual basis in December. To form the indexes, S&P Global invites approximately 4,500 publicly traded companies to participate in their Corporate Sustainability Assessment (CSA), a questionnaire that S&P Global uses to calculate each company's sustainability score on a scale of 0 to 100.

The assessed companies are then ranked within their respective industries and the highest-scoring companies within each industry are selected for the indexes. The top 10% are included in the global index, while the top 20% are added to regional indexes and the top 30% are selected for country indexes.

The North American Dow Jones Sustainability Index, for example, is comprised of the top 20% of the 600 largest U.S. companies in the S&P Global Broad Market Index based on their sustainability scores. As of June 2022, this index’s largest holdings consisted of some of the United States’ largest and most well-known firms, including Microsoft (MSFT), Visa (V), and Procter & Gamble (PG) among others.
