All environmentally relevant processes at SICK are systematically monitored, evaluated and improved regarding resource protection and emission limitation. As long ago as 2006, all German sites and manufacturing subsidiaries were certified according to DIN EN ISO 14001:2005 (SICK also successfully introduced matrix certification according to DIN EN ISO 9001:2000 and DIN EN ISO 14001:2005 for all domestic subsidiaries and at its Hungarian plant in 2007). This international standard provides guidelines for reducing water and energy consumption, as well as for cutting the use of raw materials in the manufacture of products.
