What is e-accessibility?

An accessible website is one that enables persons with disabilities to access its content and functions without difficulty.


For example, an accessible website makes it possible to:

  • Browse via speech synthesis and/or refreshable braille display (used in particular by the blind and partially sighted).
  • Customise the display of the website according to requirements (increase the size of the characters, change the colours etc.).
  • Browse without a mouse (using the keyboard alone, via a touch screen, voice or any other appropriate device).


To do this, the website must comply with the standards in force during its creation and upgrades.

Declaration of accessibility

SUEZ undertakes to make its websites, intranet sites, extranet sites and software packages accessible pursuant to Article 47 of Law No. 2005-102 of 11 February 2005.


For that purpose, it implements the following strategy and measures:

  • 2020-2022 multi-year accessibility plan: to be introduced,
  • Measures taken in 2019-2020: accessibility audit conducted in August 2020, compliance assessment work (2 workshops held by the publication date of this declaration) in order to implement the 2020-2021 action plan.
  • 2020-2021 action plan: to be introduced.


This declaration applies to https://www.suez.com.

Compliance status

suez.com does not comply with the general standard for accessibility improvement (RGAA), version 4.0 due to the non conformities and exemptions listed below.

Results of tests

The compliance audit carried out by Atalan reveals that 38 % of the RGAA version 4.0 criteria have been met, i.e.:

  • 28 compliant criteria
  • 45 non-compliant criteria.
  • 33 non-applicable criteria.


The percentage of RGAA criteria respected is calculated by dividing the number of compliant criteria by the number of applicable criteria, given that:

  • A criterion is deemed compliant if it is compliant on all pages of the sample. If a criterion is non-compliant on a single page of the sample, it is not deemed compliant to calculate the rate.
  • For a criterion to be applicable, it only needs to be applicable on a single page of the sample. This means that a criterion does not apply if it is not applicable on all of the pages of the sample, without exception.
