July 2025 update
In this blog, we spoke about the changes coming to the B Corp assessment in 2026. The B Impact Assessment is introducing stricter requirements, including mandatory carbon footprint measurement, increased environmental accountability, and a more structured climate action plan. These changes are part of B Lab’s broader shift from a flexible, points-based model to a set of non-negotiable performance requirements across seven core impact topics.
If you’re already certified or planning to pursue certification in the next 12-24 months, the time to start preparing is now.
A crucial first step is completing the Year 0 self-assessment, available through the B Impact Assessment portal. This tool helps identify performance gaps early, giving your team time to build the necessary systems before recertification. We recommend approaching this as an internal audit, using the results to create a cross-functional roadmap for ESG improvement and long-term alignment.
At the same time, growing regulatory pressure is accelerating a global shift toward third-party verification of sustainability claims. B Corps will need to support their credentials with transparent reporting and accessible, auditable documentation. You can begin preparing by measuring your Scope 1, 2, and 3 emissions, setting reduction targets, and publishing annual progress updates.
The new certification model also introduces a multi-year accountability structure. Businesses will not only need to meet Year 0 standards, but they’ll also be expected to demonstrate continuous improvement. Additional criteria will be introduced at Years 3 and 5, reinforcing the importance of long-term, embedded ESG practices.
To stay ahead of the curve, we recommend reviewing your current reporting processes and implementing tools to streamline future audits. Creating a dedicated ‘Green Team’—with representatives from across departments helping to lead the transition and ensure buy-in across key areas of your business.

In today’s rapidly changing world, businesses face increasing pressure to adopt sustainable practices and contribute positively to society and the environment. Recently, PwC reported that investors are embracing sustainability, with an 84% increase in Environmental, Sustainability, and Governance (ESG) investing expected by 2026. This represents an increase of $33.9 trillion (approximately £27.3 trillion) in funding, meaning that by 2026, more than £1 for every £5 will be invested in sustainable businesses.
To bring order to this evolving landscape, several frameworks help businesses create a credible sustainability journey. At Ecologi, we’re strong advocates of B Corp, with over 300 Ecologi businesses achieving this certification.
What is B Corp and how is it changing in 2026?
B Corp certification has emerged as a leading framework for companies striving to balance purpose and profit. Certified B Corps meet rigorous standards of social and environmental performance, accountability, and transparency.
B Corp certification, short for Benefit Corporation certification, is a voluntary accreditation awarded to businesses that prioritise people, planet, and profit equally. 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, including employees, customers, the community, and the environment. This assessment evaluates governance, worker practices, community involvement, environmental impact, and business model sustainability.
However, significant changes are coming in 2026. The B Impact Assessment will introduce stricter requirements, including mandatory carbon footprint measurement, increased environmental accountability, and a more structured climate action plan. Businesses looking to achieve or maintain B Corp status should start preparing now.
At Ecologi, we understand that this holistic approach to sustainability is crucial. Alongside addressing environmental impact, social and governance, sustainability plays an equally vital role. In 2021, we became B Corp Certified for the first time with a score of 123.7, ranking among the top 5% of B Corps for both Environment and Governance.

Why is a credible framework important?
B Corp certification 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 bound to consider the interests of all stakeholders, rather than solely focusing on maximising shareholder value. The upcoming changes reinforce B Corp’s role as a leading sustainability framework. 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.
Five 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.
Preparing for the 2026 B Corp assessment changes
Under current regulations, carbon accounting is mandatory for UK businesses with over 250 employees and a turnover of £36m or more, as per the Streamlined Energy and Carbon Reporting (SECR) framework. While the B Corp Impact Assessment already includes voluntary emissions disclosure, significant changes are anticipated in 2026, when mandatory carbon footprint measurement will be introduced.
What Will Change?
Mandatory carbon footprint tracking: All B Corps, regardless of size, must measure and report greenhouse gas (GHG) emissions.
Enhanced emissions reporting: Businesses will need to disclose Scope 1, 2, and 3 emissions.
More structured climate action plans: Companies must outline concrete steps to reduce their emissions and environmental impact.
