This report published by Tideline, discusses a potential solution to the problem of impact measurement by introducing the concept of impact classes which would be used to categorize, and compare the different impact opportunities of investments at the beginning of the investment process- much like asset classes provide frameworks for the financial opportunities of investments. With the implementation of impact classes, investors can make more informed decisions about their ventures, and the use of this classification, researchers can now analyze the impact investing market in a more accurate and structured way. The report stresses the importance of universality, simplicity, and objectivity when creating these classes for impact and that through this new implementation, the miscommunications and inefficiencies in the impact market can be tackled.
