So many challenges with data centres and AI.

There is lots of overlap between accessibility and sustainability:

https://www.w3.org/TR/2026/NOTE-llms-standards-20260324/
It's basically about quality.
I'm on the team putting together the new Web Sustainability Guidelines
https://www.w3.org/TR/web-sustainability-guidelines/
I've written up a basic set of guidance here:

There's some guidance here that is related too:

Conclusion
The 2026 WebAIM Million analysis found notable increases in both the number of detected accessibility errors and number of pages with WCAG conformance failures, reversing a trend of gradual accessibility improvements in recent years. A primary concern is the significant increase in home page complexity and ARIA code—both of which correlate to increased detectable errors.These trends likely reflect broader shifts in web development including increased reliance on 3rd party frameworks and libraries and automated or AI-assisted coding practices (“vibe coding”). Home pages are getting larger and more technologically complex at an alarming rate, making accessibility more difficult to achieve and maintain. A key takeaway from this year's report is improving accessibility at scale will require both better practices and simpler systems. Alternatively, complex systems need to do a better job of focusing on accessibility fundamentals.
A focus on sustainability also aligns with simpler, lighter code.
