Why does digital sustainability matter?

The Problem

The internet emits more CO₂ than the entire airline industry

An estimated 3.7% of global emissions come from the internet - and without change, internet emissions will double by 2030

95.8% of websites are not accessible

1 in 6 people live with disabilities, and yet 94.8% of web pages fail to meet basic accessibility standards (WCAG 2.0 level AA)

There are almost 350 million tonnes of unrecycled e-waste on earth

Software Obsolescence is a huge issue. Perfectly good devices end up in landfills simply because they're no longer supported.

Where do web emissions come from?

Breakdown

22%

of web emissions

Data Centers

Data centers consume huge amounts of electricity to power the servers used by websites, producing significant carbon emissions. There are also embodied emissions from manufacturing the servers.

24%

of web emissions

Network

The network includes the global infrastructure that transfers data across the internet - including cables, routers, and cell towers. Each time a website is visited, energy is consumed by this infrastructure. The production and installation of this equipment also create embodied emissions.

54%

of web emissions

User Devices

User devices include the phones, laptops, tablets and other devices people use to view websites. Energy is used by these devices when visiting a website, and the manufacturing of these devices add significant embodied emissions.

Methodology

Open, evidence-led scoring

Every test loads your page, measures the data it transfers, and converts that to energy, emissions and water. We estimate website carbon emissions using the Sustainable Web Design Model v4.

Page Weight - Every byte transferred, measured

Energy & Water - Grid intensity and cooling footprint

WCAG 2.2 Checks - Automated accessibility audit
