Fewer emissionsWe want to reduce emissions of organic substances and nitrogen to water by 80% and of heavy metals by 60% compared with baseline 2002.
We have set ourselves the goal of reducing emissions to water of organic substances and nitrogen by 80% by 2020 compared with baseline 2002; we want to reduce emissions of heavy metals by 60%.
Our goal is, by 2020, to reduce the withdrawal of drinking water from supply sources for production by half compared with baseline 2010. In 2013, we were able to reduce this amount by 25.3% (2012: 23.2%). We pursue the goal of establishing sustainable water management at all sites in water stress areas by 2020 by applying the European Water Stewardship (EWS) standard set down by the European Water Partnership. We introduced this voluntary industrial standard at nearly all of our European sites in water stress areas. An external audit in 2013 awarded us gold-level certification for our extensive application of the EWS standard and water management at the production site in Tarragona, Spain. In total, around 22% of our production sites were located in water stress areas in 2013, and around 7.8% of our total water supply was abstracted from these areas. Seawater accounted for 86.9% of this total.

Further reduction of emissions
Around 192 million cubic meters of wastewater were discharged from BASF production sites in 2013 (2012: 187 million cubic meters). At 2,900 metric tons (2012: 2,800 metric tons), emissions of nitrogen (N total) to water have been reduced by 86.8% since 2002. Around 19,700 metric tons of organic substances were emitted in BASF wastewater (2012: 21,200 metric tons), representing a reduction of 78.5% since 2002. Our wastewater contained 21.9 metric tons of heavy metals (2012: 26.2 metric tons), representing a worldwide reduction of 64.2% compared with 2002. Phosphorus emissions amounted to 339 metric tons (2012: 366 metric tons).
To avoid unanticipated emissions, we will review our water protection concepts at all production sites by 2015. We are constructing plants for the improvement of wastewater analytics at our sites in Ludwigshafen, Germany, and Geismar, Louisiana, which will help us to identify unanticipated emissions at an even earlier stage. The Ludwigshafen plant also contains special online monitoring systems that enable us to catch relevant pollutants in our wastewater even more quickly.
