Website built 100% with AI. In accordance with Regulation (EU) 2024/1689 on artificial intelligence (AI Act), we inform you that the design, editorial copy and part of the illustrations of this website were produced or assisted by generative artificial intelligence systems.

AI-generated or AI-edited content (presentation texts, atmospheric visuals of cities and regions) is disclosed under Article 50 of the Regulation, which requires artificially generated or manipulated content to be clearly labelled.

Factual information — members’ names and roles, hotels, dates, contact details, official texts and official member portraits — comes from documents supplied by LES CLEFS D’OR BELGIUM ASBL. It has been checked and approved by the committee: no factual data is invented by AI. The photographs of the members and of the president are authentic photographs and have not been replaced by generated images.

Human oversight: every page is reviewed and approved by the committee before publication, and the committee remains solely responsible for the editorial content.

This website runs no live AI system: no chatbot, no profiling, no biometric or emotion recognition, no automated decision-making with legal effects. Requests sent through the “Become a partner” form are handled exclusively by people.

No visitor personal data is used to train artificial intelligence models.

Carbon rating: A+. Measured on 7 August 2026: the homepage transfers about 541 KB per visit, which corresponds to roughly 0.07 g CO₂e per visit.

Other pages measured: Committee about 436 KB (≈ 0.05 g CO₂e), Become a partner about 283 KB (≈ 0.04 g CO₂e), Belgium about 611 KB (≈ 0.08 g CO₂e). Every page measured falls within class A+ (threshold: 0.095 g CO₂e per visit).

Methodology: Sustainable Web Design Model v4, computed with the Green Web Foundation’s open-source CO2.js library, based on the real transferred weight (Brotli compression included) measured on the live site with an automated browser. The model accounts for the visitor device, the network, the data centre and hardware manufacturing.

Green hosting: the site is delivered through Cloudflare, listed as a green energy provider in the Green Web Foundation public directory (verified on 7 August 2026).

Eco-design measures in place: images served in AVIF and WebP at screen-appropriate sizes, self-hosted subset WOFF2 fonts, no tracking or advertising scripts, no analytics cookies by default, lazy loading for off-screen images, per-page JavaScript splitting and immutable caching on the delivery network.

These figures are estimates from a recognised model, not certified carbon accounting. They will change as the site evolves and are re-measured at every major update.
