Anniversary celebrations in Winterthur
We’re proud to have implemented three biodiversity projects in our home city of Winterthur:
- Flora Futura Park – a municipal park that brings biodiversity to life and offers space for learning.
- Green bus shelter roofs that help improve the microclimate.
- Microforests – compact forest areas that create a valuable habitat for the the wide variety of plants and animals in an urban setting.
Green bus stops
A total of five green bus shelters have been erected in cooperation with Winterthur City Bus (in German). The small biodiversity areas have a positive impact on the city’s environment and promote urban biodiversity. You can discover the green roofs at the Haldengut, Strahlegg, Obertor, Im Link and Industriepark bus stops.
What advantages do green bus stops provide?
Green bus stops have numerous positive effects on their surroundings:
- They improve the microclimate and cool down the surrounding area. The plantings on the bus stops lower the temperature on hot summer days to create more pleasant conditions for pedestrians.
- They promote biodiversity: These plantings create tiny habitats for insects, birds and other animals right in the middle of the city, which promotes biodiversity and protects threatened species.
- They store rainwater: Green roofs store rainwater. This takes the pressure off of storm drains and lowers the risk of flooding during heavy rains.
- They improve air quality: Plants filter out fine dust and harmful substances from the air. This means green bus stops help improve air quality and promote a healthier environment for people.
Microforest
In 2025, AXA employees gave up their free time to plant two microforests together with Stadtgrün Winterthur (in German). The two public spaces Am Brisiweg in the Veltheim neighborhood and in Allmend Grüzefeld are waiting to be explored by the public.
What is a microforest?
A microforest is a tiny forested area often within a city that grows into a dense, highly diverse ecosystem within just a few years thanks to the use of a specific planting method. The concept of a microforest comes from the Japanese botanist Akira Miyawaki. The aim is to achieve a large amount of biodiversity in a very small space to improve air quality, regulate the microclimate and create habitat for many animals.
What advantages do microforests provide?
Microforests have numerous positive effects on their surroundings:
- They promote biodiversity: Microforests grow up to ten times faster than forests that are planted the traditional way and become a functioning ecosystem in just two years. This means they are an efficient reforesting method because in a relatively short amount of time they create habitat for plants and animals to promote the biodiversity of cities.
- They improve air quality: Microforests sequester carbon and filter out harmful substances and fine dust particles from the air. And they are natural air conditioners. Water evaporates from trees when it’s hot, which cools the air.
- They also minimize the risk of flooding: Through their dense vegetation and deep roots, microforests help soak up and store rainwater, which improves the soil structure and minimizes the risks of floods.
- They also improve the well-being of humans – green spaces have a positive effect on people’s emotional state. They reduce stress, improve a person’s mood and promote a general sense of well-being.
Future of the projects
The microforests initiated in our anniversary year plus the green bus shelter roofs were launched as pilot projects. They show how selective measures in the urban environment can help promote biodiversity and improve the urban space.
After implementation, the projects were handed over to the city of Winterthur. If they prove successful on a day to day basis, they can be enhanced and expanded together with Stadtgrün and Winterthur City Bus. This means that AXA sees itself as the motivator and enabler of sustainable solutions in the urban environment.
