The digital sector is responsible for approximately 3-4% of global CO₂ emissions, a figure comparable to civil aviation. Yet, unlike aeroplanes, websites can be radically optimised to consume less energy.

What is sustainable web design?

Sustainable web design is a design approach that places the reduction of a website's environmental impact at its centre, without sacrificing user experience. It is about making conscious choices on every aspect of the project: hosting, images, code, fonts, page structure.

The 5 pillars of sustainable web

  1. Green hosting: servers powered 100% by renewable energy
  2. Optimised images: WebP/AVIF format, correct dimensions, lazy loading
  3. Lightweight code: no unnecessary libraries, minified CSS and JS
  4. System fonts: reducing the number of HTTP requests
  5. Lean architecture: fewer pages, fewer requests, less data transferred
