The World Wide Web Consortium (W3C) has announced that the Web Content Accessibility Guidelines (WCAG) 2.2 have now been officially approved as an international standard by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
The standard, now published as ISO/IEC 40500:2025, represents a major step forward in ensuring that digital content is accessible and usable for everyone.
What This Means for Accessibility
WCAG 2.2 builds on previous versions of the Guidelines, offering stronger and clearer requirements to make online content more accessible to people with auditory, cognitive, neurological, physical, speech and visual disabilities.
It also enhances usability for older users and improves the overall online experience for all audiences, ensuring that digital accessibility becomes an integral part of Universal Design and Inclusion.
Since the Web Content Accessibility Guidelines were introduced in 2008, they have been adopted and referenced by governments, international bodies, and private organisations around the world. The formal publication as an ISO/IEC standard means that more countries can now incorporate WCAG 2.2 into national accessibility legislation and policy frameworks.
A Global Framework for Digital Inclusion
W3C’s collaboration with global organisations has helped shape a truly international framework for accessible digital environments. The updated ISO/IEC 40500:2025 aligns closely with other key frameworks, such as the European Accessibility Act (EAA) and EN 301 549, which regulate accessibility in Information and Communication Technologies (ICT) and digital services within the European Union.
By harmonising standards, the W3C and ISO aim to make compliance clearer and more consistent for organisations working internationally; a critical step toward building a fully accessible digital ecosystem.
Why This Matters for Organisations
For both public and private sector organisations, this update reinforces the need to review and enhance their digital accessibility practices. Websites, applications and digital communications are now expected to meet the updated criteria set out in WCAG 2.2, ensuring equal access to information and services.
Adopting these standards is not only a matter of compliance, it reflects a commitment to inclusion, innovation and corporate responsibility. Accessible design benefits everyone: it improves usability, supports better customer experience, and strengthens brand reputation.
