Global Accessibility Awareness Day (GAAD)
Building a barrier-free digital society on Global Accessibility Awareness Day
Global Accessibility Awareness Day (GAAD), observed on the third Thursday of May each year, aims to highlight the importance of ensuring inclusive access to the digital environment for everyone, especially people with disabilities. In 2026, the day will take place on 21 May and seeks to raise awareness among companies, institutions and the public about the need to design accessible websites, applications and digital content, thereby fostering a more equitable society in the digital age. This observance reinforces the idea that accessibility is not an optional extra, but an essential condition for digital transformation to be truly inclusive.

At a time when much of our daily lives –from education and employment to access to essential services– takes place in digital environments, web accessibility has become a key factor in preventing new forms of exclusion. However, millions of people around the world still encounter barriers when browsing the internet due to designs that fail to take into account diverse abilities. This day invites reflection on how the digital environment is built and encourages changes that ensure no one is left behind in the technological transformation.
What is web accessibility?
Web accessibility refers to the set of principles, techniques and best practices that enable anyone to navigate, understand and interact with websites and digital applications, regardless of their physical, sensory or cognitive abilities. The GAAD Foundation highlights the importance of taking due care with “content, navigation and interaction” to achieve this goal.
This involves designing content that can be perceived by everyone –for example, through alternative text for images– that is easy to use with different devices or assistive technologies, such as screen readers, and that presents a clear and understandable structure. Designing with accessibility criteria improves the digital experience for everyone, regardless of their abilities or circumstances.
Principles of web accessibility
Web accessibility is based on four fundamental principles defined by the World Wide Web Consortium

These principles form the foundation of inclusive design and ensure that digital solutions can be used by as many people as possible.
Why is web accessibility important?
Web accessibility is essential to guarantee equal access to information, services and opportunities in an increasingly digitalised world. According to the World Health Organization, more than one billion people worldwide live with some form of disability (around one in six people), highlighting the need to remove digital barriers.
In the European context, web accessibility becomes even more relevant with the entry into force of the European Accessibility Act, which strengthens the obligation for digital products and services to be accessible to everyone.

En el contexto europeo, la accesibilidad web cobra aún más relevancia con la entrada en vigor del European Accessibility Act, que refuerza la obligación de que los productos y servicios digitales sean accesibles para todas las personas.
What’s more, an accessible website not only improves the experience for these users, but also enhances overall usability, benefits those facing temporary or situational limitations (such as a slow connection or low-visibility conditions), expands organisations’ reach and helps ensure regulatory compliance in many countries.
The origin of Global Accessibility Awareness Day ción sobre la Accesibilidad Web
In 2011, Joe Devon, a digital accessibility advocate and web designer, wrote a blog post expressing concern about the lack of awareness and understanding of web accessibility within the technology community and proposed the creation of a dedicated day to encourage discussion and learning in this area. His goal was for the global digital community to reflect on the importance of creating websites that are accessible to people with disabilities. A few months later, Jennison Asuncion, a digital accessibility expert, came across the post via Twitter and contacted Joe Devon to promote the initiative globally.
Following this milestone, Global Accessibility Awareness Day was launched in 2012 as an initiative driven by technology professionals to focus attention on digital accessibility and the challenges faced by millions of people when using the internet.
Since then, the day has been observed every third Thursday in May and has grown in global significance, mobilising companies, developers, institutions and citizens to reflect, learn and take action in favour of a more inclusive digital environment.
Iberdrola’s commitment to web accessibility
At Iberdrola, we maintain a strong commitment to web accessibility as part of our approach to sustainability and digital inclusion. We work continuously to ensure that our digital platforms are accessible, integrating accessibility from the design phase through to the ongoing development of our digital environments.
To this end, the development of the Iberdrola website is based on compliance with the Web Content Accessibility Guidelines 2.2 established by the W3C (World Wide Web Consortium). These guidelines also form the core of standards such as ISO/IEC 40500 and the UNE 139803:2012 standard and represent the most up-to-date international benchmark in web accessibility.
We understand accessibility to be an ongoing process that requires continuous review, improvement and adaptation to new needs and technologies. Advancing towards accessible digital environments is also a way of exercising shared social responsibility and reinforcing a people-centred digital culture.
