About ICI’s Data

ICI Research examines the prospectuses of funds to classify those that invest according to ESG criteria using the same approach that it does for other categories across all funds. In particular, ICI looks for language indicating that a fund places an important and explicit emphasis on environmental, social, or governance criteria to achieve certain goals.

ICI classifies ESG-criteria funds into groups based on the frameworks or guidelines expressed at the forefront of their principal investment strategies sections.

  • Broad ESG focus: These funds focus broadly on ESG matters. They consider all three elements of ESG (rather than focusing on one or two of the considerations) or may include ESG in their names. Index funds in this group may track a socially responsible index such as the MSCI KLD 400 Social Index.
  • Environmental focus: These funds focus more narrowly on environmental matters. They may include terms such as alternative energy, climate change, clean energy, environmental solutions, or low carbon in their principal investment strategies or fund names.
  • Religious values focus: These funds invest in accordance with specific religious values.
  • Other focus: These funds focus more narrowly on some combination of environmental, social, and/or governance elements, but not all three. They often negatively screen to eliminate certain types of investments.

Data for prior dates reflect revisions due to data adjustments, reclassifications, and changes in the number of funds reporting.
