## ๐ Summary
- John Lockhart from University of Edinburgh explores how accessibility and sustainability reinforce each other in web development
- Accessible websites tend to be simpler, faster, and more energy-efficient, creating better experiences for users and the planet
- The European Accessibility Act (2025) and evolving Core Web Vitals metrics are driving increased attention to these practices
- Drupal provides strong foundation for both accessible and sustainable web development through core features
- University of Edinburgh case study demonstrates measurable improvements through student internship sustainability projects
## ๐ Main Content
John Lockhart presents a compelling argument that accessibility and sustainability are complementary forces in web development. His core thesis suggests that accessible websites are typically simpler and faster, which makes them more energy-efficient, while open web technologies reduce bloat and vendor lock-in.
The presentation addresses recent regulatory drivers including the European Accessibility Act coming into effect in 2025, requiring public sector compliance with WCAG 2.2 AA standards. Google's Core Web Vitals evolution, particularly the move to Interaction to Next Paint (INP) metrics, reflects industry focus on real-world user experience and performance.
Lockhart introduces the draft W3C Web Sustainability Guidelines, structured similarly to WCAG with four categories: user experience, web development, hosting/infrastructure, and business/product. These guidelines provide evidence-based recommendations for creating more sustainable web experiences.
Drupal emerges as particularly well-suited for implementing both accessibility and sustainability practices, with features like the Olivero theme (WCAG-compliant by default), responsive imagery, lazy loading, and robust caching already built into core.

**Accessibility and Sustainability: Better Together for WordPress**
Great news for WordPress developers focused on inclusive, efficient websites! Recent research shows that accessible websites are naturally more sustainable - they're simpler, faster, and use fewer resources while providing better user experiences.
Key takeaways for your WordPress projects:
- **Built-in advantages**: WordPress core already includes many sustainability features like responsive images, lazy loading, and efficient caching
- **Regulatory readiness**: The European Accessibility Act (2025) and evolving Core Web Vitals metrics make this work essential, not optional
- **Practical wins**: Focus on semantic HTML, image optimization, content auditing, and performance monitoring for maximum impact
Start with accessibility fundamentals and performance optimization - you'll naturally improve sustainability while creating better experiences for all users.
