Barcelona will host its annual Climate Conference on 11 and 12 June at Ca l'Alier, with the city centre stage for debate on how to adapt to extreme heat. The event is part of World Environment Day and coincides with Barcelona World Capital of Architecture 2026.
The conference will bring together citizens, climate action stakeholders, municipal officials, researchers and international experts to share knowledge and build alliances. Barcelona City Council says the aim is to address the impacts of climate change on health, quality of life and urban services.
The programme will cover the health effects of heat, urban climate adaptation, changes to buildings and public space, and the role of productive sectors in responding to the climate emergency. Speakers and participants will include representatives from universities, research centres, social organisations, trade unions, neighbourhood associations and professional bodies.

International contributors are expected from Melbourne, Dublin, Paris and Phoenix, alongside representatives from the C40 Cities network. The conference also coincides with the Cool Cities Accelerator meeting at Fàbrica del Sol from 9 to 11 June, a programme focused on measures to improve urban thermal comfort and protect residents.
Barcelona City Council will use the conference to highlight its climate adaptation work, including climate shelters, changes to educational centres, energy retrofitting of buildings and neighbourhood transformation in areas most exposed to climate impacts. The city says these measures are part of its Climate Plan and Heat Plan 2025-2035.
The event will also host the 4th Barcelona + Sustainable Agenda 2030 Awards ceremony, which recognises initiatives linked to the Sustainable Development Goals and the city’s environmental and social challenges. The awards will cover projects on decarbonisation, water saving, heat protection and urban sustainability.
