We measure important substances of concern based on the chemical oxygen demand in water (see 303-2). The identification of areas with water stress occurred as part of the risk analysis we carried out in 2018. The classification of areas with water stress is based on the Verisk Maplecroft risk assessment. In 2018, this affects our sites in Mexico, India, Singapore and Egypt.
