Assessment method

This website, like any digital product, has an environmental impact which we are going to present on this page using standardised indicators.
We use the Eco Index toolkit https://www.ecoindex.fr/ offered by the GreenIT.fr collective to assess this website’s environmental performance. This performance is measured using two types of indicators:

Our website’s eco-design score. This index assesses the best practices implemented to reduce a web page’s environmental impact. The score assigned is given on a scale ranging from A to G (with A being the best score) combined with a score between 0 and 100 (with 100 being the best score).
Water consumption and GHG emissions caused by the page loading. This index measures freshwater consumption and GHG emissions (gCO2e) generated by the loading of a web page.

Eco-design score for the website’s 5 most visited pages
Eco-design score for the website’s 5 typical user itineraries
Water consumption (in litres) and GHG emissions (kilos Co2e) caused by the loading of a web page by one user and applied to 1,000 users.
Water consumption (in litres) and GHG emissions (kilos Co2e) caused by the execution of an itinerary for one user and applied to 1,000 users.

The analysis was carried out on 20 March 2024 and is likely to change over time: the measures of environmental impacts presented below are a snippet of a given moment.

Eco-design

Eco-design is based on a method and various measures that aim to reduce this website’s impact on the environment. In practice, the approach consists of limiting the number of technical resources necessary to display a webpage or execute a function while meeting the users’ needs.

Are you a digital expert who wants to reduce your websites’ environmental impact? Below is a list of measures you can implement:

From the design stage, limit the number of features.
Remove least frequently used features.
Limit the number of carousels.
Choose lighter fonts.
Opt for simple and refined designs.
Whenever possible, adopt a “mobile first” approach.
Opt for a one-page scroll design.
Deactivate the automatic loading and playing of video and audio files.
Optimise user itineraries.
…

Measures to best manage content

Choose images over videos.
Limit the number of images on each page.
Optimise image size for target format.
Compress images using tools such as TinyPNG.
Compress PDFs using tools such as iLovePDF.
Limit the use of animated GIFs.
Choose glyphs over images.
and more.

Measures to optimise development

Opt for asynchronous processing when possible.
Only use essential portions of JS and CSS libraries.
Cache frequently used data.
Limit the number of calls to HTTP APIs.
Reduce the volume of data stored to the strict minimum.
Use the most recent version of the language.
Provide a text alternative to multimedia content.
Split the CSS.
Do not change the DOM when crossing it.
Use lazyload.
Have the W3C validate each page.
Add Expires or Cache-Control headers.
Compress text files using the following formats: CSS, JS, HTML and SVG.
Set up an efficient sitemap.
and more.

Best measures for hosting data

Choose an eco-friendly host.
Install the minimum required on the server.
Rely on managed services.
Optimise the servers’ energy efficiency.
Reduce the number of server logs to the minimum.
Apache Vhost: deactivate AllowOverride.
Use virtual servers.
Use an asynchronous server.
Store data in the cloud.
and more.
