Biodiversity Action Plan

In 2019, Singen (P&ARP and ASI) proceeded with a full evaluation of the possible impacts of the plant and its processes on biodiversity. Evaluation was done together with an environmental protection organization.

Overall the risk related to biodiversity has been assessed as moderate. Most critical aspects of our impact on biodiversity are linked to the fact that:

  • the plant occupies a large surface very near of protected areas,
  • it has CO2 emissions that participate in the climate change effect on biodiversity
  • it generates traffic that makes it more complicate for wild life mobility

On top of that opportunities to use roof surface for solar energy production have not been grasped yet.

In view of those risks (and all other identified  ones), Singen has developed an exhaustive biodiversity action plan that can be found on the following document (link to the attached excel file) It includes notably actions with the city of Singen regarding nature protection, reducing road traffic by sponsoring train usage, reducing the carbon footprint by energy saving actions as well as switching to electric forklifts and the study of the installation of solar panels.

Following this assessment, Singen has also supported a local environmental protection organization and we take advantage of our own green areas to plant flowers, thus increasing biodiversity and notably bees, butterflies and other insects close to the plant.

We will continue to constantly monitor our impact and ensure that action plans are followed through.
