Water is a valuable resource that is under pressure in Europe, with only 40% of surface water bodies being in good ecological status and 38% in good chemical status. Industrial activity leads to the release of pollutants to water, including total organic carbon (TOC) and compounds that contain nutrients such as nitrogen and phosphorous, which can cause eutrophication, and heavy metals such as Cd, Pb, Hg and Ni, which also have detrimental impacts on the environment and human health.
EU industrial policy strives to reduce pollutant emissions while supporting growth and competitiveness. Legislation, such as the Water Framework Directive (WFD) or the Industrial Emissions Directive (IED), aims to protect Europe’s water bodies from industrial emissions, among other things, thus supporting this goal. Monitoring changes in industrial emissions to water is key to tracking progress towards achieving industrial policy objectives.
Overall, industrial releases to water were lower in 2019 than in 2010: emissions of heavy metals (Cd, Hg, Pb and Ni) decreased significantly, largely as a result of decreasing releases of Pb, and emissions of nitrogen and phosphorus also decreased, although to a much lesser extent. This partly reflects the positive influence of European policy and improved pollution abatement technology on industrial emissions to water. These emission reductions were achieved despite a 14% increase in the value that European industry generated for the economy, measured as gross value added, indicating that, although European industry is growing, it is becoming less emission intensive, in line with the objectives of the EU industrial strategy.
Industrial emissions to water are reported under the European Pollutant Transfer and Release Register (E-PRTR). Although this covers the 45 substances included in the WFD’s list of priority substances, the data quality and consistency of reporting across countries are sufficient for only a small selection of water pollutants, which does not include numerous organic pollutants, pesticides and emerging compounds, such as pharmaceuticals and microplastics. Improving and widening the scope of reporting to the E-PRTR would allow for a more meaningful analysis of the impacts of industrial emissions on Europe’s water bodies.
