Becoming a B Corp is no small feat—but for many companies, it’s worth every step.

Today’s customers, employees, and investors want more than mission statements—they want proof. B Corp certification offers that proof. It signals to the market that your business meets rigorous standards for social and environmental performance, governance, and transparency. And in a world increasingly shaped by climate risk, supply chain pressure, and regulatory shifts, that credibility can open doors.

And there’s one major update: starting in 2025, B Corp requirements now include annual greenhouse gas (GHG) emissions reporting for all certifying companies with more than 250 employees or $75 million in revenue.

This change aligns B Corp standards with broader market expectations—and reinforces that climate transparency is no longer optional for businesses that want to lead.

Why companies choose B Corp certification (and what they get from it)

B Corp certification isn’t for everyone—but for many businesses, it fills a crucial gap: the need for external validation that you walk the talk on values like sustainability, accountability, and employee well-being.

So why do companies pursue it?

The real benefits of B Corp status

  • It signals credibility: Certification shows that your impact claims are backed by rigorous evaluation—not just marketing language.
  • It sharpens operations: The B Impact Assessment often uncovers weak points in governance, employee policies, supplier management, or environmental tracking. Many companies say the process improved how they run the business.
  • It attracts the right talent: More jobseekers want purpose-driven workplaces. A B Corp designation helps attract and retain people who care about more than just a paycheck.
  • It opens doors: From ESG-conscious investors to procurement teams scoring RFPs, B Corp certification can offer a competitive edge—especially as climate disclosures and social criteria gain traction in supply chains and investment screens.
  • It forces alignment: For growing companies, the framework helps align leadership, teams, and strategy around measurable, values-based goals.

Who’s made the switch—and why?

Some of the best-known B Corps didn’t start that way. They transitioned once they saw the value:
  • Ben & Jerry’s: Though known for activism, they formalized their stakeholder governance and impact tracking through B Corp certification in 2012.
  • Patagonia: A pioneer in sustainable business, Patagonia became a B Corp to anchor its mission legally and ensure its environmental commitments had external oversight.
  • Allbirds, Bombas, and Numi Tea: All cite the B Impact Assessment as a tool for operational improvement—not just a badge.

Is it right for your company?

If you’re a growing business with ambitious ESG goals—or if you’re already fielding RFPs that ask about DEI, climate targets, or community engagement—B Corp certification can help you turn loose initiatives into a system. It’s also a way to pressure test your readiness for future disclosure mandates, especially with new rules like California’s SB 253 or SEC climate disclosures emerging in parallel.
B Corp won’t solve all your problems. But it will force you to ask the right questions—and answer them in a way that builds long-term trust.

B Corp requirements

B Corp certification isn’t just a label—it’s a legally binding commitment to meet high standards of social and environmental performance, accountability, and transparency. To qualify, companies must:
  • Complete the B Impact Assessment and score at least 80 points
  • Incorporate stakeholder governance into their legal structure
  • Provide comprehensive disclosures on performance across governance, workers, community, environment, and customers
  • And now: measure and report their GHG emissions annually
B Lab’s updated standards reflect a wider shift toward measurable climate action. As of 2025, all companies exceeding the size thresholds must submit verified emissions data every year as a prerequisite for certification.

GHG emissions reporting: the new non-negotiable

Annual GHG reporting isn’t just a compliance checkbox—it’s a sign of operational maturity. The requirement aligns B Corp certification with other major disclosure frameworks like CDP, the California Climate Accountability Package (SB 253/SB 261), and SBTi.
At a minimum, companies should be prepared to:
  • Calculate and report Scope 1 and 2 emissions annually
  • Begin measuring Scope 3 emissions where feasible
  • Implement a carbon accounting system that supports year-over-year tracking

Additional B Corp requirements you should know

Beyond emissions reporting and legal accountability, B Corp certification includes:
  • Performance: A minimum of 80 points on the B Impact Assessment, which evaluates operations across governance, workers, community, environment, and customers
  • Accountability: Adopting a stakeholder-oriented legal structure (such as becoming a public benefit corporation)
  • Transparency: Publicly disclosing impact assessment scores and related data

Pro tips: avoid common pitfalls in the B Corp process

  1. Start with carbon accounting. B Lab’s emissions requirement is now foundational. Get a head start to avoid bottlenecks at the end.
  2. Engage your whole team. Certification touches everything from HR policies to procurement and legal structure.
  3. Keep good records. Every assessment answer needs documentation. Centralize your policies and reports early.
  4. Treat it as an ongoing journey. Certification lasts three years, but continuous improvement is expected.

B Corp is raising the bar—and that’s a good thing

The path to certification is more demanding than ever—and that’s exactly why it matters. With rising expectations from regulators, customers, and capital markets, voluntary frameworks like B Corp are setting the tone for what responsible business looks like in 2025 and beyond.
Done right, B Corp certification isn’t just a badge. It’s a framework that can sharpen operations, clarify purpose, and build trust with the people who matter most to your business.
