The future for web developers
It is already a legal requirement in the UK for websites run by public sector organisations to comply with WCAG 2.2 at Level AA.
Approval of ISO/IEC 40500:2025 will no doubt mean that increasing numbers of private sector organisations will in future require web developers to comply with WCAG 2.2 when making procurement decisions.

"Because WCAG is now an ISO standard, governments and organizations can formally require ISO/IEC 40500:2025 in laws, regulations, contracts, and procurement processes."
