The time has come for a new approach to ESG indexes.

The suite is comprised of three ESG index pairs: CRSP ISS ESG Large Cap Prime, CRSP ISS ESG Large Cap, and CRSP ISS ESG Large Cap Industry Balanced. Within each pair are two siblings. One sibling is comprised of “qualifying” securities that meet the applicable ESG threshold. The other sibling is comprised of “remainder” securities that don’t meet that threshold. Taken together, they offer totally transparent, completely neutral view of ESG performance across the entire large cap market. It’s a clearly different—and clearly objective—approach to ESG investing.


CRSP has designed three sibling ESG indexes utilizing the independently-generated ESG Performance scores from ISS (ESG Corporate Rating | ISS).

Performance Over Time

Based on the backtested performance since January 2015, CRSP ISS ESG Prime Index, and other ESG-qualifying pairs, show outperformance over the benchmark, CRSP U.S. Large Cap Index, and the corresponding non-ESG remainder indexes. However, the ESG-qualifying indexes performance has been impacted by the global crises in 2022, highlighting the importance of following both ESG and non-ESG complement indexes to better understand the risks and trade-offs of the ESG investment strategies.
