Cercle Européen Renert a.s.b.l. is committed to making cer.lu accessible to as many people as possible, including people with disabilities. Public debate on European questions should be open to everyone, and that includes the way we publish online.
1. Standard applied
We aim to comply with the Web Content Accessibility Guidelines (WCAG) 2.1 at level AA, as referenced in the European standard EN 301 549.
As a non-profit association, we are not a public sector body within the meaning of the Luxembourg Law of 28 May 2019 on the accessibility of websites and mobile applications of public sector bodies, and we are therefore not legally subject to it. We nevertheless choose to follow the same standard on a voluntary basis.
2. Conformance status
This website is partially compliant with WCAG 2.1 level AA. “Partially compliant” means that some parts of the content do not fully meet the standard; the known cases are listed below.
3. What we do
- The site is built on Joomla 6 with a responsive, keyboard-navigable template and semantic HTML structure (headings, landmarks, lists).
- Text can be resized up to 200% without loss of content or functionality.
- Colour contrast of text and interface elements is designed to meet the AA ratio (4.5:1).
- Images carry alternative text; purely decorative images are hidden from screen readers.
- Links and buttons have descriptive labels and visible focus states.
- Forms have labelled fields and clear error messages.
- Video and audio content published by us [is / will be] accompanied by captions or a transcript.
4. Known limitations
Despite our efforts, the following content may not be fully accessible:
- PDF publications – older reports and policy briefs may not be tagged for screen readers. We are gradually replacing them; on request we will provide an accessible version of any document.
- Third-party content – embedded videos, maps or social-media feeds are provided by external services whose accessibility we do not control.
- Event recordings – some recordings of past conferences may not yet have captions.
5. How this statement was prepared
This statement was prepared on 25 September 2026 on the basis of a self-assessment using automated tools and manual checks (keyboard navigation, screen reader testing). It is reviewed at least once a year.
6. Feedback and contact
If you encounter a barrier on this website, need content in an alternative format, or have suggestions for improvement, please let us know:
Cercle Européen Renert a.s.b.l.

E-mail:
We aim to reply within as soon as possible and to provide the information you requested in a form that works for you.
7. Compatibility
The website is designed to work with current versions of Chrome, Firefox, Safari and Edge, and with common assistive technologies such as NVDA, JAWS, VoiceOver and TalkBack. It does not require JavaScript to read the main content.
Forward-looking insight, actionable recommendations.
The CER will focus on Europe’s long-term strategic challenges, including the future of the rules-based international order including human rights, defence and broader security concerns, economic resilience and innovation ecosystems, sustainability and climate change with their global implications, and the transformative impact of digital technologies.
Our gatherings will concentrate on small, focused, and confidential sessions for genuine dialogue, complemented by a few high-profile public events for broader dissemination.
