Becoming a certified B Corp signals that your business meets the highest standards of social and environmental performance. For many organisations, one of the most important parts of that journey is calculating their carbon footprint.
With the introduction of B Lab’s updated global standards in 2025, calculating an operational footprint is no longer a nice-to-have, but a key requirement. This blog outlines what’s changed and how to approach carbon accounting in a way that supports certification and long-term credibility.
What is B Corp and how is it changing?
B Corp is a leading framework for companies striving to balance purpose and profit.
It’s a voluntary accreditation awarded to businesses that prioritise both people and planet. The certification is provided by an independent third-party organisation called B Lab. To become a certified B Corp, a company must meet specific requirements and undergo an assessment of its impact on various stakeholders. This assessment evaluates governance, customers, workers' community and environmental impact.
In 2025, B Lab introduced the most significant update to its certification framework since its launch. The previous points-based scoring model is to be replaced with baseline performance requirements across core impact areas. Rather than achieving an overall minimum score of 80 points through a mix of impact activities, businesses must now meet defined thresholds across specific topics, including carbon reporting. The new B Corp certification standards officially start for all new applicants on March 11, 2026.
Key changes under the new standard include:
Mandatory carbon footprint tracking
B Corps are now expected to measure their greenhouse gas emissions to demonstrate environmental performance and reductions over time.
Enhanced emissions reporting
Businesses are to disclose emissions across Scope 1, Scope 2, and relevant Scope 3 categories, helping provide a more complete picture of climate impact across operations and value chains.
More structured climate action plans
Businesses must outline clear strategies to reduce emissions and improve environmental performance over time, embedding climate action into business operations rather than treating it as a standalone initiative.
B Corp demonstrates a company’s commitment to pursuing a "triple bottom line" approach, considering not just financial profitability but also social and environmental impacts. B Corps are legally required to consider the interests of all stakeholders, rather than solely focusing on maximising shareholder value.
The updated standards strengthen B Corp’s role as a leading sustainability framework by introducing clearer performance expectations across key impact areas. Companies will be required to measure and reduce their environmental impact, ensuring that sustainability is fully embedded in their operations. Having a recognised, credible framework benefits businesses, customers, and other stakeholders by enabling smarter decision-making.
Four key benefits of becoming a sustainable, B Corp-certified business
Social and Environmental Responsibility: B Corp certification signals a company's dedication to making a positive impact on society and the environment.
Attracting Conscious Consumers: Consumers increasingly demand products and services aligned with their values. Certification provides a trusted and reputable symbol for responsible businesses.
Differentiation and Competitive Advantage: Certification helps businesses stand out, attracting customers, partners, and talent.
Accountability and Transparency: The certification process requires rigorous assessment and building trust with stakeholders.
