For the EU27 and Germany, the climate protection potential of the circular economy was examined for municipal waste, industrial & commercial, construction & demolition and food waste for 2017 and 2030 using the life cycle assessment method. The study shows the sector's GHG mitigation potential, including food waste prevention, in the context of the EU legal framework and the energy transition.

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 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.

Chemicals are a major driver for global warming, biodiversity loss and pollution. Bold political action is urgently needed. The Fifth World Chemicals Conference (ICCM5) 25-29 September 2023 in Bonn/Germany is bound to set up a stronger policy framework for the sound management of chemicals at global level.

In a study for the German Environment Agency, a research team from Öko-Institut and Ecologic Institute has examined the role of nature-based solutions (NbS) for global climate action and international climate policy. The results show that their potential to mitigate emissions is probably overestimated in the literature. Nevertheless, NbS can bring various benefits and should be promoted actively.

City centres have long been characterised by high levels of consumption. They now face major changes due to online retailing, the aftermath of COVID19 and the climate crisis. The UBA coordinated EU Interreg project “NiCE – from niche to centre”, started in May 2023. The project aims to take advantage of these changes and make city centres more attractive again by offering sustainable options.

The European Emissions Trading Scheme (EU ETS) will be aligned with the European climate protection target of reducing emissions by at least 55% by 2030 compared to 1990. In May and June 2023, the legal acts entered into force. Now the European Commission, in agreement with the member states, must draw up a variety of rules to implement the reform.

From 14 to 16 February 2023, the International Academy Transformation for Environment and Sustainability at the UBA (abbreviated to "TES Academy") held a three-day workshop on "Corruption Prevention as a Prerequisite for Successful Sustainability Transformation". In a video statement, the participating international experts call for cooperation in the prevention of corruption.

The EU member states are currently discussing a proposal for new regulations on packaging and packaging waste. Six new UBA fact sheets support the discussion with facts and figures, experience from regulatory implementation in Germany, and background information relevant to the proposed new regulations.

Advanced materials are innovative materials of most diverse chemical composition and form. They can offer solutions to global challenges. Examples are carrier systems for novel active ingredients or graphene for future use in batteries. To ensure that the materials are safe and sustainable over their life cycle, certain cornerstones need to be considered.

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.

100 major copper, iron ore and bauxite (“aluminium ore”) mine sites worldwide have been assessed for their environmental hazard potentials. Results have been published in an interactive map with a number of filter functions. In particular, companies can use the map to analyse environmental risks along supply chains and to support their environmental due diligence.
