Baltic Sea

Reducing substances in the construction sector that are hazardous to health and the environment and supporting circular construction – these are the goals of NonHazCity 3, a European project in the EU Interreg Program for the Baltic Sea Region. The project team involves 21 partners from all eight EU countries around the Baltic Sea, including the German Environment Agency (UBA).

Handling of fertilisers in German ports can cause nutrients to enter coastal waters. This can lead to oxygen depletion in the waters and have a severe adverse effect on living organisms. During transshipment, between 0.025 and 0.00000083 per cent of fertiliser can end up in the water. Protective covers between the ship and the quay wall and cleaning of the transshipment areas can counteract this.

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.

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.

More and larger ships are sailing the world's oceans. Due to their high tonnages, ocean-going vessels can be a comparably environment-friendly means of transport. There is still considerable potential to design and construct them in such a way that they pollute the environment less. Proposals need to be developed and implemented at all levels of maritime policy..

Oceans know no boundaries. This also applies to marine life and the spread of pollution. Effective marine protection can therefore only be achieved through intergovernmental cooperation.
