The programme "Rhine 2040", which was adopted by the Conference of Rhine Ministers on 13.02.2020, states that the "influx of micropollutants into waters from municipal waste water collection and treatment systems, industry and commerce as well as agriculture is to be reduced by at least 30 % in comparison to the period 2016-2018 - consistent with a longer-term ambition to further decrease pollution throughout the Rhine catchment area.
In order to be able to numerically check the input reduction in influx at regular intervals and, if necessary, to increase the reduction target, the ICPR is tasked with developing a joint evaluation system for the reduction across the three areas."
