Website Carbon™ Calculator v4 | What's your site's carbon footprint?

Yes, websites have a carbon footprint

The internet consumes a lot of electricity. 1021 TWh per year to be precise. To give you some perspective, that’s more than the entire United Kingdom.

From data centres to transmission networks to the billions of connected devices that we hold in our hands, it is all consuming electricity, and in turn producing carbon emissions equal to or greater than the global aviation industry. Yikes!

We developed the first methodology for estimating the carbon emissions attributed to a website. This free tool is here to help raise awareness and inspire a more sustainable internet.

If you want help doing a more detailed analysis or need assistance reducing emissions from your web project, our team would be happy to discuss your requirements.
