IRIS+ and B Impact Assessment

Original review date: 2008

Updated alignment: 2021

Metrics used in the B Impact Assessment to determine an overall rating of an organization’s social and environmental impact, irrespective of an organization’s geography.

The B Impact Assessment (BIA) is a tool to assess a company’s overall social and environmental performance.  It does so by measuring the impact of a business on all stakeholders through an online, easy to use platform.  The BIA is a free, confidential service administered by the non-profit organization B Lab.  Companies that use the BIA can be recognized for their performance by electing to become a certified B Corporation.

The BIA builds on the IRIS Catalog of Metrics in conjunction with additional criteria to come up with an overall company assessment for a variety of business models. The BIA varies based on the sector and market in which the fund or company operates.
