There’s a new package now available that puts the power of carbon-aware web design and content publishing directly into your Umbraco CMS.
It’s more than just metrics—it’s a catalyst for better performance, greener hosting, and conscientious content. By embracing its insights, your website doesn’t just look good online—it does good for the planet too.
If you’re running a site on Umbraco CMS, then this feature that we’ve now released to some of our latest clients is an important step to reducing the environmental impact of your website.
This new application automatically calculates a sustainability score, at page level and across your whole website. We’ve embedded this into our client facing dashboard so that content editors and website owners can log in and see how well the website is performing; viewing average page weights, CO₂ per view, and a breakdown of sustainability scores across all tested pages.
How Sustainability Scores Are Calculated
This lightweight package uses modern tools and established models to generate meaningful insights.
Step 1: The app visits the requested page, capturing all network requests and their transfer sizes. The total page weight is calculated from the sum of all asset sizes.
Step 2: This weight is then cross checked in a library, which applies a Sustainable Web Design methodology to convert bytes transferred into carbon emissions and energy use estimates.
Step 3: Hosting environment is checked against the Green Web Dataset to account for green hosting benefits thegreenwebfoundation.org.
Step 4: Finally, results are translated into a user-friendly carbon efficiency grade—similar to an appliance energy rating—which makes it easy to interpret and compare.
3 Key Reasons Why This Matters for Clients
We are asked more and more about sustainability and we help educate clients on the role of good content, great design and build quality on achieving really efficient web delivery. Here are 3 key reasons to reach out to us;
1. Accountability & Transparency
Our Clients can see—visibly and page by page—their site’s carbon footprint, backing sustainability claims with actual data.
2. Better Performance, Better Sustainability
Optimising page weight not only cuts CO₂ but also improves load times, reduces data usage, and boosts SEO. It’s a win-win for your environmental goals and user experience.
3. Empowered Editors & Developers
Built into our Umbraco dashboard, the tools give clear, in-context guidance. Content editors can target heavy assets and avoid bloated media—all within their regular workflow.
Thanks to this Umbraco Community Sustainability developed package, we’re helping make our clients carbon-aware of web design and content decisions more than ever before. It’s more than just metrics—it’s a catalyst for better performance, greener hosting, and conscientious content publishing. By embracing the data insights, your website doesn’t just look good online—it does good for the planet too.
