B Corp certification: a guide for businesses
Direct answer
A B Corp is a company that carries the B Corp certification from the non-profit B Lab, showing it performs demonstrably well on social and environmental matters, transparency and accountability. The certification assesses the whole company: governance, workers, community, environment and customers. To keep it, a company legally embeds that it considers all stakeholders and is reassessed periodically.
- Clear definition
- Data-driven assessment
- Risks and opportunities visible
- Practical next steps

B Corp certification: scattered information versus Energy Intelligence
Customers, staff and investors increasingly want to know whether a company lives up to its sustainability claims. A green brochure no longer convinces on its own. B Corp certification is meant as independent proof: a company has its social and environmental impact assessed and publishes the outcome. It matters most to entrepreneurs who want to show that social responsibility sits in their business model, not only in their marketing.
- B Lab, a global non-profit, awards the certification after assessing your entire operation across five areas: governance, workers, community, environment and customers.
- You legally embed in your governing documents that you weigh not only shareholders but all stakeholders.
- The certification is not permanent: you are reassessed periodically, and B Lab renews the requirements over time.
Insight
Traditional approach
Information is scattered across portals, documents, invoices or separate spreadsheets.
Modern approach
Data, context and interpretation are brought together into a clear decision picture.
Decision-making
Traditional approach
Choices are made based on averages, assumptions or occasional analyses.
Modern approach
Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.
Follow-up
Traditional approach
Actions often stay non-committal or disappear into separate reports.
Modern approach
Follow-up actions, monitoring and reporting are linked to the same energy data.
What exactly is a B Corp?
A B Corp is a for-profit company that carries the B Corp certification, awarded by the independent non-profit B Lab. Unlike a product label, the certification assesses the whole company. B Lab looks at performance across several areas: governance, workers, community, environment and the customer. The idea behind it is that a company should create value for people and the planet alongside profit, and prove it. Important to know: B Corp is a private certification, not a legal status. Do not confuse it with a benefit corporation, a legal form that exists in some countries. A B Corp may use that legal form, but the two are not the same thing.
- A certification for the whole company, not for a single product or service.
- Awarded by B Lab, a global non-profit organisation.
- Assesses governance, workers, community, environment and customers.
- It is a private certification, not a legal company form.
How do you obtain the certification?
The basis is a thorough assessment of your company through the B Impact Assessment. In it you answer questions about your policy and practice across the different impact areas. In the classic model a company must reach a minimum score, and B Lab checks the answers against supporting documents before awarding the certification. A second hard requirement is legal: you record in your governing documents that the board weighs the interests of all stakeholders, so workers, community, environment, suppliers and customers, not only shareholders. Finally, the certification is temporary. You recertify periodically, and B Lab also renews the standards itself, which means the precise requirements change over time.
- Complete the B Impact Assessment across all your impact areas.
- In the classic model a minimum score applies; B Lab verifies with supporting documents.
- Embed in your governing documents that you consider all stakeholders.
- Recertify periodically; the standards are updated by B Lab.
Why do companies do it, and what are the caveats?
Companies choose B Corp to make their values credible to the outside world. An independent certification carries more weight than a company's own sustainability page, and it helps attract customers, talent and sometimes investors who care about responsible business. There are caveats too. The assessment partly relies on self-reporting, even though B Lab checks samples and evidence. The lead time can be considerable. And there is public debate about greenwashing: critics argue that some large or contested companies should not carry the certification. The certification therefore says a company scores well on many points, not that it is perfect on every front.
- Credibility: an independent certification weighs more than a company's own claims.
- Appeal to customers, talent and values-driven investors.
- Caveat: partly self-reporting and a long lead time.
- Caveat: public greenwashing debate around some certified companies.
