Evaluation Method
Like any digital production, this website has an environmental impact that we present on this page using standardized indicators.
We use the EcoIndex framework proposed by the GreenIT.fr collective to evaluate the environmental performance of this website. This is quantified using two types of indicators:
- Website eco-design level. This indicator evaluates the implementation of best practices to reduce the impact of a web page. The level achieved is represented by a relative rating from A to G (A is the best grade) associated with an absolute score from 0 to 100 (100 is the best score).
- Water consumption and GHG emissions related to page loading. This indicator quantifies the consumption of fresh water (cl) and GHG emissions (gCO2e) related to loading a web page.
For synthesis purposes, four types of data are represented:
- Eco-design level for the 5 most visited pages of the website
- Eco-design level for 5 typical user journeys on the website
- Water consumption (expressed in liters) and GHG emissions (kg CO2e) related to loading a web page for 1 user, and reported per 1,000 users.
- Water consumption (expressed in liters) and GHG emissions (kg CO2e) related to completing a user journey for 1 user, and reported per 1,000 users.
The analysis indicated was performed on December 4, 2025, and is subject to change: the quantification of environmental impacts presented below is a snapshot taken at a specific point in time.

Eco-design
Eco-design is based on a methodology and a set of best practices to reduce the environmental impact of this website. Concretely, it involves limiting the technical resources needed to display a page or execute a feature, while staying as close as possible to the user’s needs.
Are you a digital professional looking to reduce the environmental impact of your websites? Here are some best practices to implement:
Best Practices in User Experience and Design
- Limit the number of features from the design phase
- Remove unused features
- Limit the number of carousels
- Choose lightweight typefaces
- Favor simple and clean designs
- Adopt a “mobile-first” approach when possible
- Prefer pagination to infinite scrolling
- Avoid autoplay for videos and sounds
- Optimize user journeys
Best Practices in Content Management
- Prefer images to videos
- Limit the number of images on each page
- Optimize image sizes to target format
- Compress images using a tool like TinyPNG
- Compress PDFs using a tool like iLovePDF
- Limit the use of animated GIFs
- Prefer glyphs to images
Best Practices in Development
- Provide asynchronous processing when possible
- Use only essential portions of JS and CSS libraries
- Cache frequently used calculated data
- Limit the number of HTTP API calls
- Reduce stored data volume to the strict minimum
- Use the most recent version of the language
- Provide text alternatives for multimedia content
- Split CSS files
- Don’t modify the DOM while traversing it
- Use lazy loading
- Validate pages with W3C
- Add Expires or Cache-Control headers
- Compress text files: CSS, JS, HTML and SVG
- Implement an efficient sitemap
Best Practices in Hosting
- Choose an eco-responsible hosting provider
- Install the minimum required on the server
- Rely on managed services
- Optimize server energy efficiency
- Reduce server logs to necessary minimum
- Apache Vhost: disable AllowOverride
- Use virtualized servers
- Use an asynchronous server
- Store data in the cloud
