The new OECD Handbook on Environmental Due Diligence in Mineral Supply Chains is a milestone for environmental protection in global value chains. For the first time, a clear description is given of how companies can identify, assess and prioritise environmental issues at the beginning of their global supply chains and take measures to prevent, mitigate or find solutions to arising problems.

Slow-to-degrade, mobile and partly toxic chemicals, so-called PMT/vPvM substances, can endanger our water resources over a long period of time. That is why the German Environment Agency – in line with the European chemicals regulation REACH – is calling for emissions of such substances into the environment to be minimised. The urgent need for action is shown by four new UBA studies.

A new study commissioned by the German Environment Agency shows that pesticide contamination of small bodies of water is particularly high where many pesticides are used on surrounding fields. In 80 percent of the investigated streams in Germany's agricultural landscape, the pesticides measured exceeded the limits set for animals and plants.

Sports boats and light aircraft as well as certain leisure equipment, such as bicycles, skis and musical instruments, contain fibre-reinforced composites (FRC). They are often durable, valuable and, as waste, ideally suited for preparation for reuse or recycling. However, structured processing is currently still considered uneconomical and therefore does not take place.

A new study for the German Environment Agency (UBA) foresees enormous tasks for the water supply along the Spree River if significantly less groundwater is pumped into the river with the end of brown coal mining in the Lausitz region. According to the study, in dry summer months this can lead to up to 75 per cent less water in the Spree locally.

Germany is a good place to bathe. This is confirmed by the EU Commission's report on the quality of European bathing waters, presented on 9 June 2023. According to the report, over 96 percent of the officially designated bathing water sites on lakes, rivers and coasts in Germany were rated "excellent" or "good". A total of 98 percent of all bathing water sites met the minimum requirements.

For seven years, the Marine Litter Round Table has been developing recommendations for actions against plastic pollution in the North Sea and the Baltic Sea. The contributors are meeting in Berlin with patrons, Federal Minister for the Environment Steffi Lemke, Minister for Environment of Lower Saxony Christian Meyer and UBA President Dirk Messner to present results.

The German Environment Agency has commissioned a project to study the effects of discharge water from exhaust gas cleaning systems (scrubbers) of ships on the marine environment. Scrubber discharge contains pollutants such as heavy metals and polycyclic aromatic hydrocarbons, which are classified as extremely hazardous. Discharge bans - at least regional - are recommended.

Currently, only slightly less than ten percent of rivers, lakes and coastal waters are in good ecological condition. Although this is a slight improvement over 2015, Germany still faces major challenges. According to the EU Water Framework Directive, water bodies should be "good" in terms of chemistry, ecology and – in the case of groundwater – also in terms of available quantity by 2027.

According to the German expert group report published on September 30, 2022, the most probable cause of the fish die-off in the River Oder is the rapid rise in salinity, which together with other factors led to the mass proliferation of a brackish water alga that is poisonous to fish.

Latvia will assume the two-year rotational chairmanship of the Baltic Marine Environment Protection Commission (HELCOM) on 1 July 2022. Germany’s Chair focused on biodiversity and climate, sought solutions for unexploded ordnance and underwater noise and extended measures to combat pollution of the Baltic Sea through eutrophication, hazardous substances and marine litter.

The residues of pharmaceutical drugs, plant protection products, biocides and other chemicals can have a negative impact on water bodies and drinking water quality, even in low concentrations. As part of the Federal Government's Trace Substance Strategy, interest groups are currently developing voluntary measures at roundtables to reduce the burden on the environment.
