    • Corporations much attain a minimum score on the B Impact Assessment test & re-certify every two years
  • Availability:         
    • Any business can become a Certified B Corporation, no matter what type of business entity it is or in which country/state it is incorporated
  • Cost:                 
    • Certification fees vary, based on revenues

Different types of companies require different types of certification. The four categories are:

  • Start-ups

B corp impact assessment

How Are Companies Assessed by B Lab?

The Assessment asks questions to help corporate leaders understand how—and why—“to build a better business—better for your workers, community and the environment.”

You can measure your company’s social and environmental impact on your own, using B Lab’s free, confidential B Impact Assessment.

Why Use B Corp’s Impact Assessment?

30 minutes can give you a snapshot of your company’s impact, which includes a basic summary of which things your company excels at and which it could improve upon. 2 - 3 hours gives you a full impact report, which includes a holistic report on how your company scores on a single impact topic.

Within the B Impact Assessment, you can also access improvement tools, best practices guides and case studies as well as create a customized plan for your company’s improvement. Standards and benchmarks can help you reach your improvement goal.

Why Assess Your Company and Why Change?

  • Attract & engage employees
  • Earn Press
  • Earn trust
  • Gain a competitive advantage


If you doubt that one company—yours—can make a difference in the world yet still make a profit, consider this: according to the comprehensive study entitled Sustainability Pays: Studies That Prove the Business Case for Sustainability, “businesses can improve short-and long-term profitability through the adoption of sustainable practices […].

If you don’t believe that people pay attention to or care about the sustainability issues of the corporations they work at, work with or buy from, you’re wrong.

According to the Harvard Business Review, millennials, who represent about 50% of the global workforce, seek work that connects them to a larger purpose. The Impact Assessment is designed for any type of for-profit company and any size of for-profit company.

The questions posed on the Impact Assessment will be tailored to the number of employees you indicate, so owners of a small business can take the Impact Assessment as well. The Impact Assessment “comprehensively covers the impact of a businesses on all of its stakeholders, including its workers, suppliers, community and the environment.

The Assessment also captures best practices regarding mission, measurement and governance.” The most heavily-weighted part of the Assessment deals with each company’s specific business model.

Since the Impact Assessment measures current and previous business performance rather than planned intentions, start-ups tend to utilize it only as a learning tool—since they haven’t yet existed long enough to measure their impact, start-ups can instead weave the appropriate practices into their companies for future success.
