The principles underpinning our business practices are enshrined in our Code of Conduct. It sets out the values, principles and standards of behaviour to which all K2 Systems employees worldwide are committed. We expect the same behaviour from our business partners as well.
At K2 Systems, we have always demonstrated our commitment to environmental considerations through concrete actions:
Since the very first day of operations at our main site, K2 Systems has met 100 per cent of its electricity needs from renewable energy sources. Furthermore, this site features a modern warehouse and office building. In 2024, the new building was awarded a Gold certificate by the German Sustainable Building Council (DGNB).
Renewable electricity supply at the main site and the Weil der Stadt warehouse.
of total water consumption at the main site is met by rainwater.

From values-based corporate leadership to environmentally conscious practices: We take responsibility and actively integrate sustainability into our day-to-day work.
88% of the fleet consists of electric vehicles
Whether it’s in an electric car with free charging, on a subsidised e-bike or by public transport: we support our team on their journey to work.
Water conservation in operations
We use rainwater to flush toilets in the new building at our main site in Renningen and to water green spaces. Water-saving aerators reduce fresh water consumption in the sanitary facilities. Our drinking water dispensers also eliminate the need to transport 24,500 water bottles (in 2025).
Recycling of recyclable materials and home composting
Through systematic waste separation, we channel recyclable materials into the appropriate recycling streams. We compost the organic waste generated at our head office directly on site and use the resulting compost to maintain our outdoor areas.
Environment and health in everyday office life
We have switched our administrative and documentation processes to digital workflows, thereby reducing our paper consumption. In addition, our team benefits from regional fair-trade organic fruit and targeted health promotion initiatives.
Since 2024, we have been encouraging our team to take the initiative through an in-house competition. The ‘K2 Eco Warriors Battle’ provides a framework for raising awareness and encouraging our staff to take the initiative on sustainability issues.
