Man-made climate change is a global challenge. The core task is to reduce greenhouse gas emissions and offset unavoidable emissions. Timely, sustainable infrastructure investments are key to climate action success. The focus is on reducing energy demand and a complete switch of the electricity and heat supply to renewable energies, taking into account interplay with other environmental challenges. The German Environment Agency supports this process with strategies, scenarios, measures and instruments as well as monitoring activities. It also implements individual instruments, such as emissions trading, guarantees of origin for green electricity or the Blue Angel ecolabel.
Greenhouse gas emissions in Germany fell by 3.4 percent to 649 million tonnes of CO₂ equivalents in 2024 compared to 2023, data published by the the German Environment Agency (UBA) shows.
UBA together with UNDP, UNEP, Future Earth, ISC, ITU and Kenya is championing the Coalition for Digital Environment Sustainability – CODES, which brings together science community, governmental institutions, UN Bodies, tech companies, and civil society.
The court has ruled in favour of UBA in its fight against misleading greenwashing. In its ruling of 20 February 2025, the Federal Court of Justice confirmed the decision of the lower court, the Dessau-Roßlau Regional Court. The court had imposed strict controls on general and comparative advertising. Information on offers for CO₂ offsetting must be meaninful and transparent.
The transport of passengers and freight generates greenhouse gases (GHG) – not only through the actual transport activities, but also as a result of the processes at the individual locations or through services. On behalf of the UBA, a guideline has been produced which provides information for the standardised calculation and reporting of GHG emissions along transport chains.
Revenue from European and national emissions trading in Germany totalled around 18.5 billion euros in 2024. This means that proceeds from these two key climate protection instruments was once again slightly higher than in the previous year.
As part of an in-house research project, UBA is working on the use and further development of an integrated assessment model (IAM) developed by the independent research institute IIASA. IAMs combine economic, social and ecological aspects for the development of climate action scenarios and are central to the IPCC process. The cooperation between UBA and IIASA is now official.
The outcomes of the World Climate Change Conference in Baku (COP29) have caused disappointment both in Baku and worldwide. Nevertheless, they still contribute to the international climate action process – an achievement that cannot be taken for granted given the current geopolitical situation.
On 11 November 2024, this year's UN Climate Change Conference COP29 will start in Baku (Azerbaijan). The main topics are climate finance and progress in implementing ambitious climate action. UBA experts are also part of the German delegation and are supporting the German government and the EU in the negotiations.
The winners of the German “Blauer Kompass” Prize 2024 confirmed. With over 300 applications, the nationwide competition for the highest state honour for climate crisis preparedness and adaptation once again set a new participation record.
Germany intends to become climate-neutral by 2045. This goal requires a sufficient number of well-qualified specialists to implement and advance the necessary measures on the road to a sustainable society.
Am 1. Juli 2024 ist das Klimaanpassungsgesetz (KAnG) in Kraft getreten. Für die Bundesländer bildet es den Rechtsrahmen, eigene Klimaanpassungsstrategien vorzulegen, und dafür Sorge zu tragen, dass die Kommunen Klimaanpassungskonzepte aufstellen. Eine erste bundesweite, repräsentative Umfrage im Auftrag des UBA zeigt nun, dass eine Mehrheit der befragten Kommunen bei dem Thema aktiv ist.
Water bodies can contribute to climate change as sources of greenhouse gases – this is the conclusion of a new UBA study. Modified water bodies in particular emit carbon dioxide, methane and nitrous oxide. Renaturalisation and the reconnection of floodplains can help to reduce these emissions and enable water bodies to act as greenhouse gas sinks.
