Butternut B Corp

A B Corporation (B Corp) is a certification for companies that meet high standards of social and environmental performance, accountability, and transparency. It signifies that a company is not just focused on profit but also on positive impact on society, workers, communities, and the environment.

To achieve B Corp status, companies undergo a rigorous assessment and must demonstrate commitment to balancing purpose and profit.
​

We first certified as a B Corp in 2022 and recently re-certified in August 2025. This was a massive milestone for our squad, especially as we managed to score 100.3. That is a 17.7-point improvement on our very first assessment.
​
To achieve this, we underwent a rigorous assessment that evaluated how we manage our impact across our entire business.

Being part of this network connects us with like-minded organisations committed to doing things the right way, even when it is not the easiest route. It gives us a space to learn from each other, share ideas, and collaborate to create meaningful change.

Like any progressive framework, B Lab evolves to keep pushing businesses forward. They are introducing a new set of standards and an updated assessment model to ensure the global economy works better for everyone.

💥 High Expectations: B Lab is moving away from points-based scoring. Instead, businesses must meet strict minimum standards across seven core impact topics.

💥 Total Credibility: All future certifications will be verified by independent, third-party assurance providers to strengthen trust.
​

💥 Evolving for the Future: The new framework aligns closely with global regulations, helping businesses stay ahead of emerging risks while continuing to drive real impact.

📣 In the words of our co-founders, Kev & Dave:

​
​"At Butternut, our impact is embedded in the decisions our teams make every day across the business. It’s also why we remain proud members of the B Corp community. We are part of a global movement of purpose-led businesses that believe people and planet should matter just as much as profit.

In fact, one of our proudest achievements in 2025 was re-certifying as a B Corp. We managed to increase our score across all five impact areas compared with when we first certified back in 2022. What makes this even more meaningful is that we achieved this while continuing to grow. Our squad has nearly tripled in size, our presence has expanded from three to seven markets, and we have welcomed additional brands into our family.

​The investments we made in heat recovery technology and more efficient steam ovens in earlier years continued to deliver improvements in gas efficiency. We also took this a step further when building Sam’s Kitchen, our new site in Poland, by installing an energy-efficient steam generator. This helped to build energy efficiency into Sam’s from day one.

As we expanded into new countries and progressed with Sam’s Kitchen, we also continued investing in our people. In 2025, we reduced our gender pay gap to -3.4%, down from -12.4% in 2024, moving us closer to greater gender equity across our squad.

We also continued to grow our charitable impact, increasing our donations by 26% and deepening our strategic partnership with Dogs Trust. Together, we’re helping to eliminate rabies in Thailand’s Chonburi province and improve outcomes for animals and communities alike."

As we grow, we’re committed to doing it the right way - for people, planet and pets. 🍃
