The emergence of sustainability-centric companies, initiatives and authorities are essential in order to successfully combat the issue of climate change. However, the increasing global online presence means that even sustainability-driven businesses have a digital carbon footprint. Digital carbon is an underreported aspect of global greenhouse emissions, despite accounting for as much as 4%.

In light of this, we’ve used our website carbon calculator (check out how it works here) to measure and rank the websites of more than 1000 of the world’s sustainability-focused websites by their digital carbon emissions in our biggest study to date! The problem of digital carbon is often not taken into account by businesses when measuring their sustainability, so we want to raise awareness of the fact that their digital activities have an impact too.

Below we have showcased the 25 lowest carbon websites we measured. They’re using green servers, minimalist design, and tight coding practices to achieve the top marks in our research.

Each website listed below in our top 25 is eligible for the Greenpixie low carbon award to put on your site!
