A sustainable and low-consumption website

"Digital technology takes up a considerable share of energy consumption, and that's not just a matter of image! With a view to reducing the energy consumption linked to storing our web pages on servers and the viewing of those web pages by users, we have adopted an approach that aims to minimize the size of the data they contain. Consequently, the photos presented on our website are all processed with a reduced number of pixels and the videos are selected according to a limited usage target. We have opted for simple and streamlined designs. In addition, in the development and coding of this website, we have opted to limit the flow of data between the website and the servers that host it. Lastly, the user paths have been optimized, the content such as news and press releases appear for a duration limited to: 6 months."

A more eco-responsible website.

Limiting content that causes high energy consumption: We have limited the number of multimedia files (images, videos, PDF) on each page and specifically compressed each image to a reduced number of pixels.
Optimization of the web page loading time: By reducing the data volume of the web pages and optimizing the code, we have been able to reduce the number of requests sent to the servers, and consequently the loading time.
A website that consumes less energy: We have developed the website in such a way as to optimize its efficiency and limit the load on the servers, thereby contributing to the reduction of energy consumption.
A controlled running speed: We have reduced the number of pages on our website with simplified pathways for users.
Non-autoplay videos: We have prohibited the autoplay of video content. Video content is only played by users who wish to view it, in order to limit energy consumption.

Our EcoIndex: how does it work?

The EcoIndex* score measures the environmental performance of the web pages, according to the same principle as the energy consumption labels on electrical appliances, from A to G or from 0% to 100%. To attribute a score to a web page, we use a tool called Green IT. A score is calculated for each of the web pages. Based on the web address of the page (i.e. the URL), that score takes three technical parameters into account:

the complexity of the web page composition (for the initiated, this is the number of components from the DOM, i.e. the Document Object Model) provides an idea of the level of energy that the web browser will have to consume to display the page;
the KB volume of the transferred data indicates the energy required to transmit the content from the server to the web browser
the number of necessary HTTP (Hypertext Transfer Protocol) requests from the web browser to the server.
