Challenge: The building industry accounts for 40% of global greenhouse gas emissions. Despite a $1.34 trillion market size by 2024, only 3% is for bio-based materials. This contrast highlights an urgent opportunity to adopt carbon negative materials like industrial hemp. How can we take a step towards reducing the CO2 in our communities and building an effective network for industrial hemp?

Challenge: Our cities are facing increasing heavy rains and floods, causing large damages, casualties, and costs to the built environment. Between 1980 and 2020, floods have caused over 250 billion euros of financial losses (roughly half of all climates related economic losses) and almost 5000 fatalities in Europe alone (EEA, 2023). Especially in cities, floods affect people’s lives and cause high costs for insurance companies, cities, countries, and the European Union. How can we help the citizens, companies, and local authorities, to better prepare for these events and to minimise damages and fatalities due to heavy rains and floods?
