    Light pollution, i.e., the unnecessary brightening of the night sky by artificial light, has increasingly become a nuisance for people and the environment in recent years. Unsustainable use of light sources such as neon signs, streetlamps, or sports field lighting can affect people, animals, and plants’ day and night rhythm and cause unnecessary costs for the community. Successful and sustainable lighting management, on the other hand, has the potential to save costs at the community level, increase the quality of life of community residents, strengthen animal and plant conservation, and even develop new and innovative tourism offerings.

    Together with the Federal Office for the environment FOEN, the Nature Park Gantrisch and the NGO Mountain Wilderness, we recognised that light pollution was acute but that concrete solutions were rare. Therefore, we decided to develop the “Light Toolbox.” This toolbox facilitates the implementation aid of the FOEN for the prevention of light emissions. It thus promotes sustainable lighting management and the valorisation of night-time darkness at the municipal level. Within the pilot project framework and by applying the toolbox, we developed overarching, needs-based lighting concepts together with 16 municipalities of the Gantrisch Nature Park and accompanied them during implementation. Thanks to this work, we have enabled the communities to further strengthen biodiversity protection in the nature park, reduce energy costs and conserve valuable resources.


    In the meantime, we have used the “Light Toolbox” in numerous projects beyond the pilot project, giving various municipalities easy access to the topic of lighting management.



    We developed, validated, and finalised the Lighttoolbox from scratch in close collaboration with our partners and the end-users. At the same time, we led the process of piloting the toolbox, particularly the planning, organisation, and implementation of the so-called “Lighttoolbox Atelier/Workshop” and the accompanying support of the communities in implementing the resulting lighting concepts.
