The Best for the World lists are determined based on the verified B Impact Assessment Scores of Certified B Corporations:
- The honorees featured on the Best for Community, Best for Environment, Best for Workers and Best for Customers lists scored in the top 10th percentile of all Certified B Corporations in the respective impact area. The honorees that have earned Best for Overall scored in the top 10th percentile of their overall score on the assessment across the four impact areas.
- The top scorers were calculated by size category: sole proprietor (0 employees), micro (fewer than 10 employees), small (10 to 49 employees), mid-sized (50 to 249 employees), and large (250-plus employees) businesses. Size category was determined by the company’s most recent verified B Impact Assessment prior to December 31, 2015.
- Companies were selected based on their verified score as of December 31, 2015. B Corps certified (or recertified with an updated score) thereafter will be eligible next year.
- Only Certified B Corporations with a Reviewed Version 3 or 4 B Impact Assessment (including both phone and document reviews by B Lab Staff with scores transparent online). are eligible for inclusion on the Best for the World list. While other businesses and organizations may use the free BIA to assess their own impact, they are not eligible for inclusion on the Best for the World lists. Only Certified B Corporations are eligible because they have not only obtained a verified score on the B Impact Assessment, but also have met the highest standards of public transparency and legal accountability to align their interests with the interests of society.
The B Impact Assessment (BIA) is a free online tool designed to comprehensively measure the positive impact that businesses generate for their communities, customers, workers and the environment.
The questions that a particular business sees and their relative weightings depend on the company’s industry, size and geography — there are more than 80 of these tracks in the assessment to ensure questions are material for a particular type of business.
The B Impact Assessment produces a numeric score based on a company’s responses, and a company must receive a verified total score of at least 80 points to be a Certified B Corporation. The BIA is administered by the independent nonprofit B Lab.

The lists, graphics and comparative data for the Best for the World coverage were created using B Analytics, which is a flexible data platform for measuring and managing impact at scale. B Analytics houses the largest database of social and environmental performance data on private companies globally, collected from more than 40,000 users of the B Impact Assessment.

Defining “other businesses surveyed”:
The majority of companies taking the B Impact Assessment likely already care about impact, which inflates average performance higher than what the typical company in the rest of the economy would achieve on the assessment. To counteract this sampling bias, the first question of the B Impact Assessment asks a business the following question to evaluate how important impact management is to the enterprise. Companies that the B Analytics team reports as having selected one of the first three answers have been labeled as “other businesses surveyed,” providing a more accurate picture of how a typical company would perform in the assessment:
“Select the description that best describes your business. (This is an unweighted question that will not impact your score and is asked only for research/benchmarking purposes):
- Positive social/environmental impact is desirable but not a particular focus for our business.
- Social and environmental impact is frequently considered but isn’t a high priority.
- We consider social and environmental impact in some aspects of our business but infrequently.
- We consistently incorporate social and environmental impact into decision-making because we consider it important to the success and profitability of our business.
- We treat our social/environmental impact as a primary measure of success for our business and prioritize it even in cases where it may not drive profitability.”
