Website Carbon Calculator…

See the true impact of your digital presence – and discover how to reduce it.
Every website uses energy. Every page view has a footprint.

Our carbon calculator gives you a clear, accessible snapshot of your website’s environmental impact, helping you understand how your digital presence contributes to global emissions. It’s a simple first step toward building a faster, cleaner, more sustainable website.

Why your website’s carbon footprint matters…

The internet might feel invisible, but its energy use is very real. Every image loaded, every script executed, and every server request consumes electricity – and that electricity often comes with a carbon cost. By understanding your website’s footprint, you can make informed decisions that reduce emissions, improve performance, and align your digital presence with your organisation’s values.

How the calculator works…

Our tool estimates the carbon emissions produced each time someone loads a page on your website. It looks at factors such as:

  • Data transfer size – how much information is being sent to the user
  • Energy intensity of data centres and networks
  • Device energy use
  • Hosting efficiency

This approach is based on widely recognised industry methodologies, giving you a reliable, transparent starting point for understanding your digital impact.

Once you’ve entered your URL, you’ll see:

  • Estimated COâ‚‚ emissions per page view
  • Annual emissions based on typical traffic
  • How your site compares to global averages

These numbers help you understand where you stand today – and where you could be with a more efficient, lower‑carbon website.

Why get a deeper analysis?

A quick estimate is useful, but a detailed audit reveals what’s really driving your emissions. With a full analysis, we can identify:

  • Oversized images and media
  • Inefficient code or scripts
  • Heavy third‑party integrations
  • Hosting inefficiencies
  • Opportunities for structural or design improvements

This gives you a clear, prioritised roadmap for reducing your footprint while improving speed, accessibility, and overall performance.
