Assessment method
Like any digital production, this website has an environmental impact, which we present on this page using standardised indicators.
We use the EcoIndex framework proposed by the GreenIT.fr collective to assess the environmental performance of this website. This is quantified using two types of indicators:
- The website's eco-design level.
This indicator assesses 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 being the best rating) combined with an absolute score from 0 to 100 (100 being the best rating). - Water consumption and GHG emissions related to page loading.
This indicator quantifies the consumption of fresh water (cls) and GHG emissions (gCO2e) related to the loading of a web page.
For summary purposes, four types of data are presented:
- Eco-design level for the five most visited pages on the website
- Eco-design level for three typical user journeys on the website (investors, customers and candidates)
- Water consumption (expressed in litres) and GHG emissions (kilograms of CO2e) associated with loading a web page for one user, reported per 1,000 users.
- Water consumption (expressed in litres) and GHG emissions (kilograms CO2e) associated with completing a journey for 1 user, reported per 1,000 users.
The analysis shown was carried out on 08/01/2026 and is subject to change: the quantification of environmental impacts presented below is a snapshot taken at a given moment in time.
The measurements were taken using the Ecoindex CLI and EcoindexAPI tools available on the official cnumr repository.
