The Global Cities Dialogue is an international network of Mayors and High Political Representatives who believe that the development of the Information Society should be for the benefit of all the citizens, communities and peoples of the world. For this reason, they committed themselves to this goal by signing the Declaration of Helsinki "Mayors of the World for a Global Cities Dialogue on the Information Society" and getting actively involved in creating equal opportunities and access for all citizens.
From 2000 up to 2010 Issy chaired the Global Cities Dialogue, a worldwide network of about 200 mayors committed to sharing good practices in order to create an Information Society free of digital divide.
The direct representation of mayors in the dialogue ensures the necessary credibility and political authority. Cities are challenged to play a true leading role by contributing with concrete actions and committing themselves to turning their vision of the dialogue into fruitful initiatives for the Information Society.
Today, the GCD network has approximately 200 members worldwide and since March 2007 it is registered as an international non-profit-making organization under Belgian law.
The whole activity and sustainability of the network relies on the active involvement of its member cities in promoting concrete actions and joint initiatives to enhance the digital inclusion. Numerous collaborations within joint projects arose from the GCD network.

The GCD was launched in 1999 by twelve founding members who decided to commit themselves to the development of the Information Society for the benefit of all regardless of race, social position, creed, gender or age. At that time, GCD was the world's first initiative based on a joint commitment by cities - represented by their mayors and HPRs - to work tirelessly for realising this promise of equal opportunities and access. Over the last decade it has invited nearly 200 cities across the five continents to join in this worthy, effective and dynamic enterprise.
