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 2012, we were able to reduce this amount by 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 (EWP). We will introduce this voluntary industrial standard initially at our European sites in water stress areas. In total, around 22% of our production sites were located in water stress areas in 2012, and around 6.9% of our total water supply was abstracted from these areas.

Reducing emissions further
Around 190 million cubic meters of wastewater were discharged from BASF production sites in 2012 (2011: 192 million cubic meters). At 2,800 metric tons (2011: 2,900 metric tons), emissions of nitrogen (N total) to water have been reduced by 87.3% compared with 2002. Around 21,600 metric tons of organic substances were emitted in BASF wastewater (2011: 24,300 metric tons), representing a reduction of 76.4% since 2002. Our wastewater contained 26 metric tons of heavy metals (2011: 24 metric tons), representing a worldwide reduction of 56.8% compared with 2002. The higher amount of heavy metal emissions compared with the previous year was largely the result of production increases at the Ludwigshafen site. Phosphorus emissions amounted to 366 metric tons (2011: 391 metric tons).
To avoid unanticipated emissions, we will review our water protection concepts at all production sites by 2015. We plan to additionally invest around €4 million in improving wastewater analytics at the Ludwigshafen site. This will enable us to identify any unanticipated emissions at an even earlier stage.
Furthermore, we also want to minimize the risk of water contamination from our products. We have participated in the roundtable Zusammenarbeit von Wasserversorgung und Agrarchemie (Water Supply and Agricultural Chemistry Cooperation) since 2009, which aims to prevent the contamination of drinking water with crop protection products. Within the framework of this cooperation, a monitoring database was set up for Germany which comprises around 8,000 water retrieval points. In 2012, this data helped us to identify affected drinking water catchment areas and develop initial measures to address the issue.
