B Impact Assessment (and GIIRS Rating) Aligned Metrics

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 and funds that use the BIA can be recognized for their performance by electing to become a certified B Corporation or Global Impact Investment Rating System (GIIRS) rated.

The BIA (and therefore GIIRS rating system) uses IRIS metrics in conjunction with additional criteria to come up with an overall company or fund-level rating, as well as targeted sub-ratings in the categories of governance, workers, community, environment, and socially and environmentally-focused business models. The BIA varies based on the sector and market in which the fund or company operates.

The table below documents the set of IRIS metrics that are included in the BIA for organizations operating in developed and emerging markets.

As with all IRIS metrics, it is important to state that interpretation of these metrics must also take into account other aspects of a company's context, and changes over time. Stand alone numbers cannot by themselves indicate positive or negative social value, or necessarily be compared across companies or products.

Required Metrics – Emerging Markets

Data-compliant metrics tracked in the core B Impact Assessment, with questions around governance, workers, community and environment.

Required Metrics – Developed Markets

Data-compliant metrics tracked in the core B Impact Assessment, with questions around governance, workers, community and environment.

Optional Metrics

Metrics related to the optional survey questions covered in the Impact Business Model (IBM) section. Companies can report on a number of these metrics based on their own socially or environmentally-focused business model.

Referenced Metrics

Additional IRIS Metrics that are highlighted in the B Impact Assessment help text but not data-compliant.
