Examples of websites that are both sustainable and accessible
Target skills
Let's take a few examples of accessible sites that have a low environmental impact.
We have used the GREENIT.FR tool, EcoIndex, to measure the impact of some of the most accessible websites. This tool analyzes a number of criteria on a web page and gives an environmental impact score.
EcoIndex is a free and transparent community tool that, for a given URL, allows to evaluate:
- its absolute environmental performance using a scot out of 100 (higher is better);
- its relative environmental performance using a grade from A to G;
- the technical footprint of the page (weight, complexity, etc.);
- the associated environmental footprint (greenhouse gases and water).

This site is fully compliant with WCAG 2.1 guidelines. A dedicated accessibility page provides resources for tailoring the experience to your needs, links to assistive technologies and a list of known accessibility issues that are being addressed. It is customizable for individual users (colors, text size), uses short sentences and large, clean fonts throughout the site for maximum readability.
The site is fully compatible with screen reading software.

The calculation of its environmental impact with Eco index gives a result higher than 75 corresponding to the letter A, the best grade in the ecoscore scale.
