For the first time, some of Switzerland’s largest cities are meeting for a dialog

The SDG Flag Day took place at the Asilo Ciani in Lugano. For the first time, representatives of the largest Swiss cities came together for an open dialog on sustainable urban development and the implementation of the 2030 Agenda. The participants ranged from the city presidents to the delegates of the Federal Council responsible for sustainable development and the director of the Swiss Association of Cities.

Since 2019, Swiss cities, municipalities, companies and organizations have been sending out a clear signal for the 17 Sustainable Development Goals every autumn. Raising the SDG flag stands for the commitment to the 2030 Agenda and the will to tackle global challenges together. In Lugano, Federal Councillor Ignazio Cassis opened the event with a video message and emphasized Switzerland’s key role in sustainable development at national and global level. A special feature of this year, the SDG Flag Day was used as a platform for metropolitan exchange, from administration to innovation promotion

Exchange, practical examples and youth visions
The dialog revolved around the status of the 2030 Agenda in cities, best practices and the role of international networks for urban transformation. The delegations discussed challenges ranging from climate change to biodiversity, but also opportunities arising from cooperation between science, business, politics and civil society. The presentations by high school students from Lugano, who presented their visions for urban development in 2030 in the “Laboratori di cultura urbana – Mediazione Giovani”, were particularly impressive. Their “Summer Islands” project was implemented together with the city and the Institute of Architecture and stands for youth engagement and participatory urban development

Framework and principles of the 2030 Agenda
With its 17 SDGs, the 2030 Agenda, which was adopted by the UN member states in 2015, defines the international framework for action to tackle challenges such as climate change, resource consumption and social inequality. Their aim is to reconcile prosperity and the planet through partnership, peace and progress and to create sustainable living realities worldwide. Flag Day is part of the UN Global Compact and is used in Switzerland and internationally as a symbol of commitment and exchange

The SDG Flag Day in Lugano was the starting signal for more intensive and networked cooperation between cities in the area of sustainable development. The lived practice of dialog, exchange and participation at several levels makes it clear. The implementation of the SDGs is not a competition, but a joint project for the future of society throughout Switzerland and beyond its borders.
