How Website Carbon Testing Helps Strengthen Your Environmental Score for B Corp Renewal

For B Corps, renewal isn’t just about holding on to your certification. It’s about showing that you’re continually making measurable changes that prove your commitment to balancing profit with purpose.

When it comes to the Environmental section of the B Impact Assessment (BIA), many organisations focus on energy, waste, and supply chain. But one area that’s often overlooked is the carbon impact of your website.

Why your website matters for B Corp scoring

Your website is part of your scope 3 emissions, the indirect environmental impact of your digital supply chain. Every page load consumes energy through data transfer, hosting, and user devices. On high-traffic sites, this adds up quickly.

By addressing the carbon impact of your website, you can contribute points across multiple areas of the BIA:

• Climate: measuring and reducing greenhouse gas emissions.
• Energy, Water & Materials: showing reductions in IT and operational energy use.
• Suppliers: engaging hosting and technology partners in sustainability.

How website carbon audits support B Corp renewal

At Consider Digital, we run website carbon measurement audits with a robust and verified rationale that give you:

• A benchmark of your current website emissions in CO₂e.
• Practical recommendations to cut that footprint through design, code, and hosting choices.
• A retest and comparative report showing measurable reductions.
• Documentation you can submit as part of your B Corp renewal evidence.

This means you’re not only reducing your environmental footprint, you’re also strengthening your B Corp application with clear, verifiable action.

Why this matters now

B Lab standards get more demanding with every renewal cycle. Having specific, measurable initiatives like website carbon audits demonstrates the continuous improvement reviewers look for. And since relatively few B Corps have tackled their digital footprint, it’s also a chance for your business to stand out as a leader in sustainable practice even amongst B Corps.
