Why did we conceive
GreenWeb Index?
What would be the best method to become aware of the environmental impact of a website?
Simply by knowing this impact. Long considered non-existent, for lack of the «cloud» analogy, this absence somewhere in the sky, the footprint of digital and more precisely digital services is a reality that it is necessary to make visible.
With more than 5,000 sites tested, we have enabled as many people as possible to become aware of the challenges of a more responsible digital environment.
What is GreenWeb Index?
The GreenWeb Index tool allows you to test the environmental impact of a website page.
It was designed by combining several Open Source technology bricks that allow data to be collected, and linked to the right databases, through a computational algorithm.
The GreenWeb index is calculated from 5 main criteria
Data transferred when loading a page.
The energy used by data centers, telecom networks and terminals.
The type of energy production used.
The carbon intensity of the energy used.
The audience of the website.
These criteria are weighted by
Energy intensity of web data: 1.8kWh/GB.
The monthly audience of the site according to the average number of pages viewed.
The carbon intensity of different energy sources:
- 475 grams CO2e per kWh.
- 33.4 grams CO2e per kWh for renewable energy.
