In August, Horizon takes a look at the quest to make Europe’s cities environmentally sustainable, while also ensuring a healthy and prosperous population. We speak to geographer Professor Harriet Bulkeley on why cities have such an important role in fighting climate change, what it means for a city to be sustainable and the big challenges that lie ahead. We look at the construction of zero-energy housing, homing in on the case of Nottingham, UK, and find out how scientists are putting nature back into the old Spanish capital of Valladolid. We also talk to the city officials breathing new life into historical buildings in Bologna, Italy, and learn how urban planners and architects are taking emotional feedback into account when designing new public spaces and homes.

Mobile forests could help cities cope with climate change

Cities across Europe are trialling schemes such as roof gardens and ‘mobile forests’ to embed more nature into urban areas in an effort to protect their citizens from climate change events like heatwaves, floods and droughts.

‘Reverse fridges’ and insulated walls – how to make a house carbon neutral

As the world moves towards a carbon neutral future, many different areas from industry to manufacturing are working to reduce their emissions. But scientists are beginning to look at a different area – houses – to work out if it’s possible to reduce emissions from Europe’s homes to zero by retrofitting on a mass scale. And the early signs are promising.

Emotional response to city design could guide urban planning

Virtual reality and scenario-testing models are being built to help urban planners and architects get real-time feedback about the impact of their designs on mental health, particularly for older people.

People in cities hold the key to ensuring a sustainable future

Cities have a critical role to play in fighting climate change but hard conversations lie ahead about the best way to achieve the transition to sustainability, according to Harriet Bulkeley, professor of geography at Durham University, UK.
