The UK B Corp movement has reached a new milestone, with the first 20 businesses certified against B Lab’s tougher new standards. The development comes as the UK community passes 3,000 B Corps, marking a significant shift in what certification now requires from businesses looking to demonstrate their social and environmental impact.
Introduced in 2025 following a multi-year review, the new standards represent the biggest overhaul of B Corp certification to date. Rather than allowing businesses to focus primarily on their overall impact score, the framework introduces minimum requirements across key areas including climate action, human rights, governance and accountability, alongside a stronger focus on impacts throughout the value chain. Certification is also now supported by a new third-party audit process.
The change reflects a wider shift in expectations around corporate sustainability. Businesses are increasingly being asked to demonstrate not only that they have ambitious commitments, but that those commitments are embedded into how they operate, make decisions and manage their wider relationships. Under the new B Corp framework, continual improvement is a core requirement, making certification less of a destination and more of an ongoing process of measuring, improving and addressing business impacts.
For supply chains, this could have particular significance. The new standards place greater emphasis on understanding and improving impacts beyond a company’s direct operations, bringing areas such as procurement, suppliers, workers and wider value chains further into the sustainability conversation. For businesses working towards more responsible supply chains, this reinforces the need to move beyond high-level commitments and consider how sustainability is reflected in everyday commercial and operational decisions.
The businesses leading the first wave include companies from a wide range of sectors, including Huel, Mulberry, Medik8, Fussy and VIVOBAREFOOT. Their different business models demonstrate that the new requirements are not limited to one type of organisation, but are intended to provide a common benchmark for businesses across the economy.
For businesses operating across complex supply chains, the impact of these standards is already visible in how leading B Corps are approaching their environmental footprint. Mulberry’s latest Impact Report identifies upstream and downstream transport and distribution within its Scope 3 emissions, contributing to a total carbon footprint of 11,760 tCO₂e in 2024/25. VIVOBAREFOOT has also focused on understanding the emissions associated with its inbound supply chain, reporting visibility of CO₂ emissions data across sea, air and road shipments. The company has subsequently made sustainability a specific part of its logistics procurement, including environmental criteria within its tender process for logistics partners. These examples show how sustainability commitments can translate into practical decisions around procurement, transport and distribution, rather than remaining at the level of corporate targets.
The growing B Corp movement also raises an important question for businesses that have not yet started this journey: what does responsible business look like when expectations are becoming more demanding? As sustainability moves further into procurement, logistics, governance and commercial decision-making, businesses will need to demonstrate how their ambitions translate into measurable action across the systems they influence.
