Our managed sites average ‘B’ on Website Carbon

Written by Bailey Bryan - August 7, 2025

We recently launched version 4 of the Website Carbon Calculator, our free tool to help accelerate the shift toward a more sustainable Internet. We make this available because we can’t build or maintain every website in the world, that in itself isn’t sustainable! Tools like this help to contextualise website emissions to take steps on your own digital estates.

But the ones we do build? We make sure they’re sustainable as they grow.

We work with many people post launch, and after retesting our current client’s homepages and service pages, the average score was a ‘B’. 

A ‘B’ is a good score that indicates sustainable progress, but we’re never satisfied with ‘good enough’. We know it’s possible to reach an ‘A’, and that’s what we strive for. Websites should always be evolving toward better performance, in line with their business growth.

Where there’s growth, there can be bloat

Okay, I recognise that is not the sentence we all wanted to read – but it’s the truth! As businesses grow, there’s often an urge to add more to the website. It’s natural, but sometimes it leads to unnecessary bloat. And while adding more can feel like progress, it can hurt the site’s performance and impact the user experience.

We start builds with low-carbon, efficient code, but that’s just the beginning. The real goal is to make sure that every person interacting with the site has a meaningful, enriching experience. This is where education and collaboration come in. Together, we can make sustainable design choices that benefit both the planet and the people interacting – internally and externally.

A true balancing act! But it is possible; Humanitarian Practice Network is a shining example of displaying varied types of content without increasing its impact on the planet and giving a rich experience for a global audience.

Digital sustainability is not a one and done

We always aim for an ‘A’ score at site launch, but we need to think of websites as living things that needs care and attention to stay healthy and high-performing. That’s where continuous iteration of the site is key and keeping Experience Principles front of mind.

With us by our client’s side, we design thoughtful solutions to business developments, campaigns and product launches – demonstrating to your audiences you care about all their interactions with you. We’re on a mission, and we want to bring you along with us! If an image upload is too big, don’t worry, we’ll help you fix it and share a tip or two with your team to prevent it in the future.

Long-term vision

We can’t improve what we don’t measure. Regularly benchmarking our websites helps keep sites in flow with new tools, user needs, and the ever-changing digital landscape – like AI. It’s important to us to be transparent about our own work too because digital sustainability is a journey, not a destination.
