No.: 4/2022Newsletter "UBA aktuell"

Dear readers,

Climate change is making itself increasingly felt in Germany. This newsletter focuses on what we can all do – whether in politics, the economy or in our private lives – to combat the increasing incidence of extreme weather.

Good news for climate protection: in the first half of 2022, renewable energy sources generated about 14 percent more electricity in Germany than in the first six months of last year.

Whilst we're on the topic of climate: as you will see, the content of this newsletter is organised by topic. You will now find all the news on a particular topic under the new headings, be it the latest news, a new publication, or an upcoming event. We would appreciate your feedback on this change and any suggestions you have for improving the “UBA aktuell” newsletter. Please take part in this short survey to let us know.

Wishing you an interesting read,

Heat, drought, and heavy rainfall: what Germany can do about it

Because of climate change, Germany is facing more and more hot summer days with temperatures above 30 °C and tropical nights with temperatures of at least 20 °C. Heat waves are now at least five times more likely than they were in 1900. This is particularly detrimental to vulnerable people such as the elderly and those with pre-existing medical conditions in densely populated inner cities. Extensive ground sealing and building development, as well as little greenery, result in particularly intense heat in these areas.

Climate change is also resulting in a decrease in soil moisture in Germany. As of 15 July 2022, the topsoil (down to 30 cm) showed drought stress throughout almost all of Germany, and in some cases extreme drought stress, and this had corresponding consequences not only for forests, agriculture, and forestry. At the same time, rain is increasingly falling as heavy rain – which runs off quickly, sometimes leaving devastation in its wake, as was the case last year in the Ahr valley.

In addition to the rapid reduction of environmentally harmful greenhouse gas emissions, there is an urgent need to adapt to the consequences of climate change. We need to combat the heat in the inner cities by significantly increasing the amount of green space and providing more shade through external sun protection on buildings. Dedicated floodplains along the rivers can help to prevent damage from heavy rain and simultaneously retain water in the landscape for dry periods. Water needs to be used carefully everywhere, which is to say that it should be kept free of pollution and used sparingly; for example, by mulching in agriculture to avoid the soil drying out, or by collecting rainwater in private gardens and only watering the garden in the cool morning or evening hours.

Systematically perform climate risk assessments in municipalities

Municipalities are affected differently by climate change due to various factors. The German Environment Agency (UBA) therefore recommends the implementation of municipal climate risk assessments along three essential steps: preparation, implementation and communication of the results. To support this, a handout provides information on the methodological procedure in addition to ISO 14091. read more

First half of 2022: Significantly more electricity from wind and sun

In the first half of 2022, renewable energy sources generated about 14 percent more electricity than in the first six months of last year, in Germany. Initial estimates from the Working Group for Renewable Energy Statistics (AGEE-Stat) suggest that the share of renewable energies in gross electricity consumption was about 49 percent. This figure was just 41 per cent for 2021 as a whole. read more (in German)


Renewable energies in Germany

Data on the development in 2021

On behalf of the Federal Ministry for Economic Affairs and Climate Affairs, the Working Group on Renewable Energy Statistics (AGEE-Stat) takes stock of the use of renewable energies and annually prepares an official estimate of the development of renewable energies for the previous year. This background paper describes the initial findings for the electricity, heat and transport sectors, more

Rebasing the Cap and strengthening the Market Stability Reserve in the EU ETS until 2030

The EU Commission has proposed to reduce emissions in the European Emissions Trading Scheme (EU ETS) by 61 % up to 2030. Apart from the cap, the market stability reserve (MSR) regulates supply and scarcity on the carbon market. This report looks at different options to rebase the cap and to adjust the MSR parameters. It analyses the effects on total allowance supply and on the total number of more

Designing cities that are liveable and sustainable for all

Heat, noise, air pollutants and a lack of green space often become concentrated in disadvantaged urban neighbourhoods – to the detriment of people's health and quality of life. Good examples from municipal practice demonstrate how different stakeholders can work together successfully to achieve greater environmental justice and healthy environmental and living conditions for all population groups. read more (in German)

OECD-Guideline: Determination of particle size of nanomaterials

On 30th June 2022, the OECD published the Test Guideline No. 125, which harmonises the determination of particle size distribution specifically for nanomaterials. It is an important building block for the implementation of nano-specific requirements within the framework of legislation on chemical safety, for example for the REACH Regulation. read more

Pesticide authorisations threaten our groundwater and drinking water

The quality of drinking water in Germany is excellent. Its main source, groundwater, is afforded a high level of protection and should be as free from chemical residues as possible. The current legal framework for the authorisation of pesticides, however, poses a threat to the quality of groundwater and drinking water in the long term, as it is currently only possible to limit substance inputs into groundwater to a limited extent. read more (in German)

Refinement of the P assessment of ionisable substances: Distribution and degradation of anionic, neutral and cationic organic chemicals in water-sediment systems

The criteria for the assessment of ⁠PBT substances were developed for neutral organic substances. Many chemicals are, however, charged under environmentally relevant pH conditions. The influence of a charge in molecule on its potential to degrade in the environment is unclear and therefore the research question of this project. The results show that especially a positive charge can strongly more

Noise effects of the use of land-based wind energy

Wind turbines are important for a sustainable energy supply. Noise from these turbines is often discussed in politics, the media and the public. Amplitude-modulated noise, which is perceived as " whooshing ", is also a topic of discussion. The aim of this research project is to investigate the generation of amplitude-modulated noise and its influence on noise perception of the residents living more

Final data on nitrogen dioxide levels in 2021

The nitrogen dioxide (NO₂) measurement data for 2021 for all air monitoring stations in Germany are available: the annual mean air quality limit of 40 micrograms NO₂ per cubic metre of air (µg/m³) was exceeded in Munich, Essen, and Ludwigsburg.

Bacterial resistance in sewage sludge

Sewage sludge contains a multitude of substances that we do not want in the environment. These are transferred into the sewage sludge during wastewater treatment. The quality of the sludge depends on factors such as location. A new study has shown that the size of a sewage treatment plant has no influence on the occurrence of resistance genes or resistant bacteria and pollutants in sewage sludge. read more (in German)

The issue of microplastics in soils - a danger for humans and the environment? You can see a hand with a magnifying glass examining the soil.

International Conference: Microplastics in Soils

Microplastics are usually associated with marine pollution. But scientific studies are increasingly pointing to soils being a major sink for plastic debris. On October 19-20, 2022 the German Environment Agency (UBA) will hold an international (hybrid-)conference in Berlin to shed new light on the impact of plastic pollution on soils. read more


EU agricultural policy: "Greening" produced hardly any improvement for the environment

When "greening" was introduced as part of the reform of the Common Agricultural Policy (CAP) in 2013, the aim was to improve water and soil quality, protect the climate, and increase biodiversity. This has only been achieved in a very minor way, and it has also come at a high price. This is the conclusion drawn by a study by the Thünen Institute on behalf of the German Environment Agency. read more (in German)
