Section 3 describes the B Impact Assessment (BIA), a comprehensive, free tool generated by B Lab, to assess, compare, and implement improvements that are good for workers, the environment, communities, governance, and customers. This section provides insight, resources, and best practices to help companies strengthen their social and environmental impact, whether or not they are pursuing certification. B Lab has established an independent standards advisory council that designs and updates the BIA on a three year cycle.

How to Use Business as a Force for Good (page 62)

The B Impact Assessment (BIA) is a free, confidential, and easy-to-use online management tool to help businesses assess, compare, and improve their social and environmental performance. This online assessment takes two to three hours to finish. B Lab recommends that the first draft be completed by the CEO or another champion who has a broad perspective on the company’s strategic direction and operations. The assessment is divided into the Impact Areas of Workers, Community, Environment, Governance, and Customers. Initially, the BIA measured companies on a scale from 0 to 200 points, with companies scoring 80 or above qualifying for certification. The ceiling of 200 points was removed in V6 of the BIA, released in January of 2019. The resulting B Impact Report is a one-page summary that shows how the company performed in each section and can help businesses create a plan to improve performance. In each Impact Area, the authors:

  • Highlight important ways businesses can affect change
  • Explain why these actions are rewarded on the assessment
  • Give advice as to how the practice can be implemented
  • Integrate diversity, equity, and inclusion (DEI) considerations

Worker Impact (page 68)

There are many aspects of workers to consider. The section highlights how the BIA measures the efforts of employers to support their employees and offers tips, resources, and advice to help companies make improvements.

Community Impact (page 92)

Behaving as a socially and environmentally responsible corporate citizen will benefit the organization by improving their ability to attract and retain talent, generate positive media attention, and increase the goodwill of their customers. Transparency can encourage other companies to follow suit and shows stakeholders that its commitment to multiple social values is authentic and verifiable.

Environmental Impact (page 122)

Addressing and working to improve the impact that a company has on the environment is not only better for the planet, but will also improve a company’s profitability in the long run. Many companies have found that improving their environmental performance helps them to attract top talent, create strong relationships with suppliers, and increase trust and credibility with their customers. Further, the consequences of climate change have historically had a disproportionate impact on indigenous communities, women, the elderly, those with disabilities, and the poor.

Governance Impact (page 136)

Building a business that is good for the environment, good for workers, and good for the community is a challenge in and of itself. Once established, how does a company ensure that the purpose-driven policies and practices remain in place, especially through changes in employees, ownership, and management? One of the great benefits of being a Certified B Corp is having the ability to ingrain the company’s purpose-driven goals into its mission statement and legal DNA.

Customer Impact (page 151)

Excellent customer service and offering quality products not only is a core component of a company’s strategy but is also one of the primary ways for a business to cultivate long-term relationships and create value and positive impact for these stakeholders.

Discussion Prompts

  • What do you see as the most challenging section in the assessment (workers, community, environment, governance, or customers)? Why do you think it would present a greater challenge than others? Is there a strategy to minimize this challenge? Will this differ by industry, size, or current legal status?
  • Who do you think should complete the B Impact Assessment for a company? Is there a good way to avoid personal bias when making selections?
  • Do you think it would be easier or more difficult for private companies to complete the assessment compared to publicly traded companies?
  • Many organizations have taken the BIA even if they didn’t want to pursue the certification. Why do you think taking the BIA can be valuable for an organization if they don’t pursue the certification?
  • How does the assessment differ in different regions of the world?
