Will the City of the Future Be Greener?

Global warming increases the overheating of cities worldwide. More and more people today live in traffic-optimized urban areas characterized by concrete and asphalt. Significant cooling effects can be achieved on and around buildings with plants and their evaporation capacity.

Basel is considered the “world capital of green roofs”. With the scientific-practical World Congress 2025 as well as a complementary Green Building Week 2025, knowledge transfer is combined with illustration on practical examples through excursions in Basel and throughout Switzerland.

Uniting Experts in Science,
Planning & Architecture

The World Congress 2025 is aimed at scientists, planners, architects, landscape architects, construction experts, greening specialists and representatives of public authorities.
