Moving towards digital sobriety

1/ What is eco-friendly design?

Eco-friendly design designates the best practices aimed at reducing the environmental impact of a product during its design. This approach applies to a wide variety of domains, and in particular to the digital domain (including website design). Did you know that the weight of a web page multiplied by 155 between 1995 and 2022 and is continuing to grow? In terms of carbon footprint, new technologies emit more greenhouse gases than civil aviation! Source EcoIndex:


2/ What does eco-friendly website design entail?

In practical terms, eco-friendly website design aims to reduce water consumption and greenhouse gas emissions, and improve the performance and browsing of pages, whilst ultimately noticeably improving the user experience!

Eco-friendly design is a focus throughout the lifecycle of the project, from design to development and not forgetting subsequent updates. It involves acting on a number of key factors to reduce digital pollution:

  • Improving accessibility in accordance with the RGAA criteria.
  • Optimising the information architecture to ensure a more efficient user experience.
  • Compressing the website’s development resources and files.
  • Limiting carousels, animated GIFs and other superfluous animations.
  • Reducing the size of media files (images, videos, audio, etc).
  • Limiting cookies, or even using no cookies.

All of these optimisations help to limit IT equipment renewal, which is the main source of digital ecosystem pollution.
