BetaCheck your website sustainability and performance
Make your website a mean green growth machine
Why test your website's carbon footprint?
When users visit your website, it uses electricity. Heavy, bloated websites use more power, which means more carbon emissions.
Many people don't know that unsustainable websites also underperform and cost more to run. The same inefficient code that creates carbon emissions also makes your site slow and frustrating to users, which isn't great for business.
Cogworks' free advanced Website Carbon Calculator, built by our sustainability team, analyses carbon and performance to show you where the problems are and how to fix them for maximum environmental and business value.
Not all website carbon calculators are born equal
Built on the Green Web Foundation's trusted methodology, our carbon calculator reveals more than emissions—it exposes the performance gaps costing you money and carbon.

The carbon calculator shows what's wrong. Our digital sustainability consulting makes it right, transforming data into faster sites that marketing loves, greener infrastructure that compliance can report on, and hosting bills that make IT heroes.
As this calculator is in beta, we are continuously working to improve its accuracy and usefulness, with the ultimate aim of providing a truly helpful and transparent tool for understanding website sustainability. This thorough approach, even in its development phase, strives to provide a realistic baseline of your site's performance and environmental impact, forming the foundation for informed, actionable insights.
