How Carbon-Efficient Indices Can Shape the ESG Landscape What happens when an index incentivizes behavioral changes by design?
BY Mona Naqvi

INTRODUCTION



The S&P Global Carbon Efficient Index Series is designed to reduce carbon exposure while maintaining similar levels of risk/return to the benchmark. Most notably, the index series incentivizes behavioral change among companies by uniquely encouraging two things:



• Greater corporate transparency by rewarding companies that disclose greenhouse gas (GHG) emissions with a 10% boost in index weight; and



• The diversification of company business models toward lowcarbon alternatives as companies seek to improve their standing in the index.



The latter is achieved by assessing the carbon performance of companies (based on GHG emissions data from Trucost), sorting them into deciles within GICS® industry groups, and reweighting accordingly. However, since some industries are inherently more GHG emitting than others, our methodology considers the spread of possible emissions within an industry group and increases or decreases company weights by either a greater or lesser extent, depending on how much a company can feasibly improve given current available technologies.



For example, a highly carbon-efficient Energy company in the top decile of the broad-ranging Energy industry is likely to be far ahead of its peers and, thus, deserves a significant weight increase of 120%. Conversely, a Media company in the top decile of the smaller-ranging Media industry only receives a small weight increase of 20%, as it is only slightly ahead of its peers. Vice versa, a high-emitting Energy company in the bottom decile would get a weight reduction of 90% versus just 15% for a Media company in the same position (see Exhibit 1). As such, companies are incentivized to both disclose and decarbonize to boost their overall standing—to the extent that they are able to.
