What is B Corp Certification?
B Corp certification is a private certification issued by B Lab, a nonprofit founded in 2006 by Jay Coen Gilbert, Bart Houlahan, and Andrew Kassoy. To earn certification, a company must complete the B Impact Assessment (BIA)—a comprehensive evaluation covering five areas: governance, workers, community, environment, and customers. The company must score at least 80 out of 200 points, undergo a verification review by B Lab staff, and amend its governing documents to require consideration of all stakeholders.
As of 2025, over 8,000 companies across 90+ countries hold B Corp certification, ranging from small startups to multinational brands like Patagonia, Danone North America, and Natura &Co. The certification has become a recognized market signal for consumers, employees, and investors who want evidence that a company's social and environmental claims are substantiated.
The certification process is rigorous and has gotten more demanding over time. B Lab updated its standards in 2024, raising the bar on climate action, living wages, and supply chain transparency. Companies must recertify every three years, and B Lab conducts random audits. High-profile decertifications—including some well-known brands that couldn't meet updated standards—demonstrate that the certification carries genuine accountability.
What is a Benefit Corporation?
A benefit corporation is a legal corporate structure—not a certification. It's a type of for-profit entity recognized by statute in 40 U.S. states plus Washington D.C., as well as in Colombia, Italy, Ecuador, and several other jurisdictions. When a company incorporates (or converts to) a benefit corporation, it embeds stakeholder consideration into its legal DNA.
The legal structure addresses a specific problem: traditional corporate law in many jurisdictions has been interpreted to require directors to maximize shareholder value above all other considerations. This creates legal risk for executives who want to prioritize environmental or social outcomes when they conflict with short-term profit. Benefit corporation statutes explicitly authorize—and in some cases require—directors to consider the impact of decisions on workers, communities, the environment, and other stakeholders.
Benefit corporations must produce an annual benefit report assessing their overall social and environmental performance against a third-party standard. However, unlike B Corp certification, there's no minimum score requirement. The benefit report is a transparency mechanism, not a performance threshold. This means a company can be a legal benefit corporation without demonstrating any particular level of social or environmental achievement—it simply must report on its efforts.
Key Differences
1. Certification vs. Legal Structure. B Corp is a performance certification you earn. Benefit corporation is a legal form you register. One is verified by a private organization; the other is filed with the state. They operate in entirely different domains—market signaling versus corporate law.
2. Performance Requirements. B Corp demands a minimum score of 80/200 on the B Impact Assessment, with verification and recertification every three years. Benefit corporation status requires only an annual benefit report with no performance floor. You can technically be a benefit corporation with poor social and environmental outcomes.
3. Geographic Availability. B Corp certification is available globally—any company anywhere can apply. Benefit corporation status depends on local legislation. If your state or country hasn't passed a benefit corporation statute, the legal structure isn't available to you.
4. Cost and Complexity. B Corp certification involves significant time (6-12 months for the assessment process) and annual fees scaled to revenue. Benefit corporation registration costs roughly the same as any corporate filing—a few hundred dollars at most.
5. Accountability Mechanism. B Corp certification is enforced by B Lab, which can revoke certification if standards aren't maintained. Benefit corporation accountability comes through the legal system—stakeholders can bring a "benefit enforcement proceeding" if directors fail to consider stakeholder interests, though such suits remain extremely rare.
6. Brand Recognition. The B Corp logo and "Certified B Corporation" designation carry significant consumer and investor recognition, particularly among younger demographics. Benefit corporation status doesn't come with a standardized mark, and public awareness of the legal structure remains lower.
7. Complementary Design. These aren't competing options—B Lab actually requires B Corps incorporated in states with benefit corporation statutes to adopt benefit corporation (or similar) legal status. The two mechanisms are designed to work together: legal protection plus verified performance.
Which One Do You Need?
If you want to signal your commitment to stakeholders with a recognized, verified credential, pursue B Corp certification. The BIA process itself is valuable—many companies report that going through the assessment revealed operational improvements they hadn't considered. The certification also opens doors to the B Corp community, preferential procurement programs, and growing consumer segments that specifically seek certified businesses.
If you want legal protection for mission-driven decision-making—particularly if you're concerned about future investors, acquirers, or board members prioritizing short-term profit over stakeholder impact—adopt benefit corporation status. It's inexpensive and provides a legal foundation that can't be revoked by a new CEO or board.
For maximum credibility and protection, pursue both. This is B Lab's recommended approach and reflects the reality that certification without legal backing is vulnerable to mission drift, while legal status without certification lacks external verification. Companies like Patagonia, Allbirds, and Warby Parker hold both.
If you're outside the U.S. and benefit corporation legislation doesn't exist in your jurisdiction, B Corp certification gives you a path to demonstrate and verify stakeholder commitment without requiring a specific legal structure.
Council Fire's Perspective
We consistently recommend that mission-driven companies pursue both B Corp certification and benefit corporation status where available. The legal structure protects your mission during the moments it's most vulnerable—fundraising rounds, leadership transitions, acquisition offers. The certification proves you're actually delivering on that mission, not just claiming to.
What excites us most is the ecosystem effect. B Corp companies increasingly prefer doing business with other B Corps, creating supply chains where stakeholder consideration is the norm rather than the exception. This network effect—over 8,000 companies and growing—is quietly building an alternative model of capitalism that doesn't require government mandates to function.
Frequently Asked Questions
Can any company become a B Corp?
Any for-profit entity can apply, regardless of size, industry, or geography. However, meeting the 80-point threshold is genuinely challenging. B Lab reports that the median score for companies taking the BIA for the first time is around 50, meaning most companies need to make operational changes before qualifying. Some industries face structural barriers—fossil fuel extraction, weapons manufacturing, and certain other sectors are ineligible regardless of score.
What happens if a B Corp doesn't recertify?
Companies must recertify every three years. If a company fails to recertify—whether by choice or because it no longer meets the standards—it loses the right to use the B Corp certification mark and is removed from B Lab's directory. Several prominent companies have been decertified in recent years, which B Lab argues demonstrates the integrity of the standard. The company retains its benefit corporation legal status if applicable, as that's independent of B Lab's certification.
Does benefit corporation status affect taxation?
No. Benefit corporations are taxed identically to traditional corporations—either as C-corps or S-corps depending on their election. The benefit corporation designation affects governance obligations and liability protections, not tax treatment. There's no tax advantage or disadvantage to choosing the benefit corporation structure over a standard corporation.
How does B Corp certification compare to ESG ratings?
They measure different things at different scales. ESG ratings (MSCI, Sustainalytics) evaluate publicly traded companies on material ESG risks for investors. B Corp certification evaluates any company's holistic social and environmental performance against an absolute standard. ESG ratings are relative to industry peers; B Corp certification is an absolute threshold. A company can have a strong ESG rating and not qualify as a B Corp, and vice versa, because the assessment frameworks emphasize different factors.
