Evaluation method

Like any digital production, this website has an environmental impact, which we present on this page using standardised indicators.

We use the EcoIndex benchmark proposed by the GreenIT.fr collective to assess the environmental performance of this website. This is quantified using two types of indicator:

– Level of eco-design of the website: This indicator assesses the implementation of best practices to reduce the impact of a web page. The level achieved is represented by a relative evaluation from A to G (A is the best score) combined with an absolute score from 0 to 100 (100 is the best score).
– Water consumption and GHG emissions linked to page loading. This indicator quantifies the freshwater consumption ( cls) and GHG emissions ( gCO2e) associated with loading a web page.

For summary purposes, four types of data are represented:

– Ecodesign level for the 5 most visited pages of the website
– Ecodesign level for 5 typical user paths on the website
– Water consumption (expressed in litres) and GHG emissions (kilos CO2e) linked to the loading of a web page for 1 user, based on 1,000 users.
– Water consumption (expressed in litres) and GHG emissions (kilos CO2e) associated with the execution of a user path for 1 user, based on 1,000 users.

The analysis shown was carried out on 07/10/2024, and is subject to change: the quantification of environmental impacts presented below is a snapshot taken at a point in time.

Ecodesign

Ecodesign is based on a methodology and a set of best practices to reduce the impact of the website on its environment. In practical terms, this means limiting the technical resources needed to display a page or execute a function, while meeting the user’s needs as closely as possible.

Are you a digital professional looking to reduce the environmental impact of your sites? Here are a few best practices to implement:

Some good practices in terms of ergonomics and design
Limit the number of functions at the design stage
Delete unused features
Limit the number of carousels
Choose typefaces with reduced weight
Favour simple, uncluttered designs
Adopt a mobile-first approach wherever possible
Prefer pagination to infinite scrolling
Avoid automatic playback and loading of videos and sounds
Optimise user paths
…
Some good practices for content management
Prefer images to videos
Limit the number of images on each page
Optimise the size of images to the target format
Compress images using a tool such as TinyPNG
Compress pdfs using a tool such as iLovePDF
Limit the use of animated GIFs
Use glyphs instead of images
…

Some good development practices
Offer asynchronous processing whenever possible
Use only the essential parts of the JS and CSS libraries
Cache calculated data that is used frequently
Limit the number of calls to HTTP APIs
Reduce the volume of stored data to the bare minimum
Use the most recent version of the language
Provide a text-based alternative to multimedia content
Cut CSS
Do not modify the DOM when traversing it
Use lazy loading (lazyload)
Validate pages with W3C
Add Expires or Cache-Control headers
Compress text files: CSS, JS, HTML and SVG
Setting up an efficient sitemap
…
Some good hosting practices
Choose an eco-responsible host
Install the minimum required on the server
Rely on managed services
Optimise server energy efficiency
Reduce server logs as much as possible
Apache Vhost: disable AllowOverride
Use virtualised servers
Use an asynchronous server
Store data in the cloud
…
