How can the immense potential of digitalisation be tapped for the benefit of all without consuming excessive resources and energy? These and other questions were discussed by over 150 international experts with the support of the German Environment Agency (UBA) at the virtual conference of the Coalition for Digital Environmental Sustainability (CODES) on 30 June and 1 July 2021.

Access to all German environmental information and data via one platform – that is the goal of the new National Environmental Information Centre, which the Federal Ministry for the Environment will set up in Merseburg from the summer of 2021.

A research project for the German Environment Agency developed a method for the systematic analysis of the design of nationally determined contributions (NDCs) of Parties to the Paris Agreement. As part of this project, the design of 20 NDCs were analysed with this method.

At its first meeting on May 25, 2021, the newly formed Resources Commission at the German Environment Agency (UBA) was constituted for the appointment period 2021 to 2024. The Resource Commission consists of 18 experts from science, industry, administration, and civil society, who were personally appointed by the President of UBA.

The German Environment Agency proposes a national cap on nitrogen emissions. By 2030, no more than 1 million tonnes of nitrogen per year is to be emitted into the environment. Only then can existing protection goals for water bodies, terrestrial ecosystems and human health be achieved.

Airborne ultrafine particles can be harmful to human health. A study by the German Environment Agency (UBA) at Frankfurt Airport has demonstrated that ultrafine particle (UFP) load in the vicinity of airports can be significantly elevated. Engine emissions are shown to be the major cause, contributing 90 per cent of total load.

Measured concentrations of nitrogen dioxide (NO2) in 2020 exceeded the annual mean limit of 40 µg/m³ of air at only about 3 to 4 percent of measuring stations located near road traffic, compared to 21 percent in 2019. Nitrogen dioxide pollution overall continues to decline throughout Germany.

Climate change will affect the frequency, intensity and regional occurrence of extreme weather events and lead to gradual climatic changes. Although impacts appear locally at first, they spread beyond political borders due to the global physical and economic interconnectedness. A new UBA report provides an overview of the potential impact chains of global climate change on the German economy.

Greenhouse gases, nitrogen emissions and other environmental pollution cause damage to human health and destroy ecosystems. They also lead to production losses, crop losses and damage to buildings and infrastructure. For many of these damages, there are established scientific methods to express them in monetary terms.

On 30.11. and 1.12.2020 the conference „PFAS - Dealing with contaminants of emerging concern“ took place. Experts from Europe and around the world exchanged views online on how to deal with environmental pollution caused by poly- and perfluorinated alkyl substances (PFAS). Because of their unique properties, these more than 5,000 substances are used in a wide variety of products.
