In April 2025, B Lab introduced a significant overhaul of its B Corp Certification standards, transitioning from a cumulative point-based system to mandatory minimum standards across seven Impact Topics. This change reflects the growing urgency to ensure businesses prioritise sustainability and accountability. Among these new Impact Topics, ‘Climate Action’ has been introduced to address one of the most pressing challenges of our time: climate change.
What is Climate Action?
The introduction of ‘Climate Action’ as a dedicated Impact Topic highlights the critical role businesses must play in mitigating climate change. This section of the standards focuses on how companies measure, reduce, and disclose their greenhouse gas (GHG) emissions, while also implementing robust strategies to achieve net-zero targets. By embedding climate responsibility into their operations, B Corps are expected to lead the way in driving the systemic change necessary for a sustainable future.
How is Climate Action Different from Previous Standards?
Under the old B Lab Standards, climate considerations were addressed indirectly, primarily through the ‘Environment’ assessment area. While businesses were encouraged to report on their environmental practices, the emphasis on climate-specific actions was not as pronounced.
The new “Climate Action” Impact Topic brings a sharper focus on actionable requirements, including:
Setting and Disclosing Targets: Businesses must set science-based targets for greenhouse gas (GHG) emissions aligned with the 1.5°C pathway and publicly disclose their climate commitments and progress.
Measuring and Reporting: Companies are required to measure GHG emissions annually and report measurable progress toward net-zero emissions, including reductions achieved each year.
Implementing a Climate Action Plan: A formal climate action plan must be developed, implemented, and continuously improved to ensure alignment with global climate objectives.
Prioritising Renewable Energy and Efficiency: Organisations must prioritise renewable energy use and energy efficiency across their operations and supply chains.
Addressing Scope 3 Emissions: For larger companies, efforts must extend across value chains to tackle Scope 3 emissions, which often represent the largest share of a company’s carbon footprint.
Additionally, businesses are required to publicly disclose their climate commitments and progress, enhancing transparency and accountability.
Why Do These Changes Matter?
The inclusion of “Climate Action” underscores the urgent need for businesses to step up and address their role in the climate crisis. By requiring companies to implement science-based solutions and take responsibility for their emissions, B Lab aims to drive meaningful contributions toward global climate goals. This shift not only reinforces the credibility of the B Corp certification but also positions businesses as leaders in the transition to a low-carbon economy.
