Die EU-Staaten haben endgültig grünes Licht für die überarbeitete Richtlinie zur Energieeffizienz von Gebäuden gegeben und die neuen Vorgaben formell beschlossen. Kadri Simson, EU-Kommissarin für Energie, begrüßte das Votum: „Eine bessere Gesamtenergieeffizienz von Gebäuden ist von entscheidender Bedeutung, um unser Ziel der Klimaneutralität zu erreichen und die Energieunabhängigkeit Europas zu stärken. Renovierungen sind Investitionen in eine bessere Zukunft.“
Net public electricity generation reached a record share of 59.7 per cent in 2023. The share of the load was 57.1 per cent. This is the result of an analysis presented today by the Fraunhofer Institute for Solar Energy Systems ISE. New records were set for wind and solar power in 2023. In contrast, generation from lignite (-27 per cent) and hard coal (-35 per cent) fell sharply. Photovoltaics stood out in the expansion of generation capacity: at around 14 gigawatts, the expansion was in double digits for the first time and significantly exceeded the German government's statutory climate protection target.
More rail transport, reformed motor vehicle tax and less fossil heating needed
Germany can still achieve its climate targets by 2030. This is shown in a new analysis by the Federal Environment Agency (UBA). This would require, among other things, more rail transport, a reform of the motor vehicle tax and the restriction of fossil heating. In addition, all emissions would have to be priced and charged to the polluter. In the so-called Climate Protection Instruments Scenario 2030 (KIS-2030), the UBA has examined how additional emissions can be saved in the building, mobility, energy and industry sectors. "The model calculation clearly shows that we have a lot of catching up to do in some sectors," says UBA President Dirk Messner. "We now urgently need a constructive dialogue about where emissions can be reduced, otherwise we will miss the legal savings targets. We also need to talk honestly about how to cushion the financial burden on lower-income groups and distribute it more fairly. Currently, low-income households are often asked to pay disproportionately. Understandably, this does not exactly increase acceptance for more climate protection.
The Federal Cabinet today approved the draft of a timber construction initiative presented by Federal Minister of Construction Klara Geywitz and Federal Minister of Agriculture Cem Özdemir. This strategy of the Federal Government is intended to strengthen the use of wood as a sustainable raw material in the construction sector and to ensure more climate protection, resource efficiency and faster construction. With eight fields of action, from the exemplary role of the federal government and the strengthening of research and innovation, to securing skilled labour and knowledge transfer, to securing the supply of raw materials, the use of wood is to be significantly improved and the timber construction quota increased by 2030.
Scientific scenarios on climate neutrality support corporate strategy and planning on the path to decarbonisation - Using the example of buildings and heating, climate economists at DIW Berlin analyse existing scenarios on climate neutrality - Net zero scenarios show a clear path for the transformation of companies and the financial sector - With standardised scenarios and transition plans for climate neutrality, banks, funds and insurance companies can make their portfolios fit for the future.
On 16 June, the member states of the European Union approved a comprehensive revision of the EU Renewable Energy Directive (RED) in the Committee of Permanent Representatives. The European target for renewable energies will thus be significantly increased from the previous 32% to 45% in 2030. This means a doubling of the share of renewable energy compared to the level reached in 2021 of just under 22%. This is a great success for the expansion of renewables: It roughly doubles the planned expansion of renewable energy by 2030. To achieve the new targets, more than 100 GW of new wind turbines and solar installations will be installed in the EU every year. For Germany, this means that the significantly increased expansion targets for wind and solar energy in 2022 will be underpinned by European targets and become binding. The higher EU targets also form the framework for further measures and targets in the EU, such as the EU's solar strategy, which aims to roughly triple PV capacity to 600 GW by 2030.
PV strategy presented
Today, Federal Minister of Economics and Climate Protection Robert Habeck presented the second PV-The aim is to significantly accelerate the expansion of solar energy in Germany. The goal is to significantly accelerate the expansion of solar energy in Germany. To this end, the strategy identifies measures in a total of eleven fields of action. The spectrum ranges from measures in the area of energy policy to the topics of securing skilled labour, industrial value creation in Europe and technology development. This was preceded by a first photovoltaic summit in March 2023. Since March, the PV strategy has been consulted. More than 600 comments were received.Proven work aid and at the same time standard work for climate protection work in municipalities can be used digitally in future. Difu, ifeu and Climate Alliance developed the guide on behalf of the BMWK.
The housing shortage is an immense social problem in many large cities and conurbations. At the same time, the building sector has been failing to meet its environmental and climate targets for years. In a recent position paper, the Federal Environment Agency (UBA) and the Commission for Sustainable Building at the UBA (KNBau) have examined how more affordable housing can be created without unnecessarily harming the environment and health. According to this paper, the most important factor for more environmental protection in housing construction is that the existing building stock is preserved wherever possible or is sensibly converted and repurposed. This is the easiest way to avoid climate emissions and unnecessarily high consumption of raw materials. Today, UBA President Prof. Dr. Dirk Messner presented KNBau's proposals to Federal Minister of Building Klara Geywitz and Federal Minister of the Environment Steffi Lemke in Berlin.
The Federal Ministry of Transport, Building and Urban Affairs is supporting the climate-friendly construction of new buildings with a new funding programme that will start on 1 March 2023. For the first time, the entire life cycle of a building will be considered - from construction to operation to potential deconstruction in the distant future. The buildings are characterised by low greenhouse gas emissions in the life cycle, high energy efficiency, low operating costs and a high proportion of renewable energies for the generation of heat and electricity. This funding thus makes a contribution to climate protection and to meeting national climate targets.
The "Climate Adaptation Check" is a new orientation aid for NRW municipalities. The federal state passed the first climate adaptation law in Germany in 2021. The check supports NRW municipalities in implementing the new requirement for consideration. Berlin/Cologne. The consequences of climate change have long been felt in German municipalities: more frequent heavy rainfall events, flooding, storms as well as heat waves and prolonged drought. Cities, [...]
Researchers at DIW Berlin have developed the "Ampel-Monitor Energiewende" - monitor the extent to which the government's energy policy agenda is being implemented - immense efforts are needed to close the gap between the announced targets and the current status quo
Thüga closed the 2021 financial year with a good result. The approximately 100 municipal utilities and regional suppliers of the Thüga Group fully fulfilled their supply mandate and continued to drive forward the energy turnaround despite burdensome general conditions.
Is German climate policy on the right path? A national CO2 budget for Germany allows for a transparent comparison with international targets. In a paper published today, the Environmental Council updates its calculations for a German CO2 budget, showing that fast emission reductions are crucial - last year, climate targets for transport and buildings were missed again. The paper also answers frequently asked questions about the CO2 budget.
Germanwatch now urgently expects political signals following the conclusion of the interim technical negotiations / Special challenge on the issue of damage and loss recognised, now it is a matter of concrete financing proposals
The cities propose to strengthen and accelerate local climate protection through a new financial support system. The German Association of Cities today published a concept and a publication on its website.
Recommendations from the BMBF project "Urban Heat Transition" were published: ► Consistently tapping alternative heat sources such as wastewater heat ► Convert public buildings to renewable heat and create neighbourhood heating networks ► Ambitious energy refurbishment in neighbourhood conservation areas to keep rents affordable
The Federal Cabinet today adopted the so-called Easter Package at the proposal of Vice Chancellor and Federal Minister for Economic Affairs and Climate Protection Robert Habeck. This is the largest amendment to energy policy legislation in decades. The Easter Package comprehensively amends various energy laws in order to accelerate and consistently drive forward the expansion of renewable energies.
After a significant decline in the previous year, greenhouse gas emissions in Germany are on the rise again. Thus, around 762 million tonnes of greenhouse gases were released in 2021 - a good 33 million tonnes or 4.5 percent more than in 2020. Overall, emissions in Germany have thus fallen by 38.7 percent since 1990. The increase in the last year is particularly noticeable in the energy sector: This shows an increase of 27 million tonnes CO2-equivalents, as increased demand for electricity, lower electricity generation from renewable energies and the higher gas price led to increased use of coal for electricity generation. Electricity generation from renewables fell by seven per cent, mainly due to poor wind conditions. In the transport and building sectors, emissions were above the annual ceilings set by the Federal Climate Protection Act. This is shown by the latest calculations of the Federal Environment Agency (UBA), which are based on the specifications of the Federal Climate Protection Act and the EU-Renewable Energy Directive (RED) were presented today.

NATURSTROM is expanding its largest local heating project to date in Markt Erlbach, Franconia. In future, the green energy supplier will supply over 130 customers with sustainable and locally generated heat - including households, municipal buildings and a large commercial enterprise. Bavaria's largest solar thermal plant is being built on an area of 2,400 m2 for this purpose.
In December 2020, the German Timber Industry Association (HDH) launched the "Initiative for Climate Protection in the Timber Industry". The aim is to support the industry companies in the necessary reduction of CO2 emissions. The initiative is now being further developed into an innovation cluster.
The property developer WvM Immobilien + Projektentwicklung GmbH and the eco-energy supplier NATURSTROM AG found the joint company Green Estate. With the fusion of energy and real estate know-how, the partners are taking a new path to enable people to live sustainably.
at the Sustainable Procurement Symposium in Dortmund on 26 August 2021 The Sustainable Procurement Day is a platform for exchange for procurers and decision-makers from municipalities, private and public institutions as well as churches and companies. Federal Environment Minister Svenja Schulze is the patron. The Agency for Renewable Resources e. V. (FNR), project management agency of the Federal Ministry of Food and Agriculture, will be represented with a workshop on the topic of "Public building and renovation with wood - the right way to tender for timber construction projects" in addition to the stand "The renewable office".
With a very large majority, the municipal council decided on 22.07.2021 to initiate the urban development measure (SEM) "Nördlich Hafner". The development statute provides the project with a binding legal framework for the city of Constance and the remaining property owners in the area. The decision is also the conclusion of the preparatory studies (VU) that have been running for about four years, in which not only various subject-related studies and the urban development framework plan were developed, but also a comprehensive timetable and a detailed cost and financing overview were drawn up. The development of the approx. 106 ha area (of which approx. 60 ha are residential areas) including all technical and social infrastructures (e.g. day-care centres, primary school) will cost a total of almost 420 million euros. Income from the allocation of land will ultimately result in a largely balanced overall balance.
How can Wuppertal become a climate-neutral city by 2035? This question is discussed by the Wuppertal Institute in this new study, which was presented by Lord Mayor Uwe Schneidewind on 1.7.2021.
Sascha Müller-Kraenner, Federal Director of Deutsche Umwelthilfe (DUH), comments on today's debate on the Renewable Energy Sources Act (EEG) in the Bundestag: "The Grand Coalition is breaking its promise to set higher expansion targets for renewable energies for the year 2030 before the end of this legislative period. An agreement failed primarily due to the energy transition obstructionists within the CDU/CSU parliamentary group. The German government is thus ignoring the implementation of the new EU climate targets and disregarding the decision of the Federal Constitutional Court to tackle more ambitious climate protection measures before 2030. The amendment to the Renewable Energy Sources Act is missing the centrepiece. At the end of 2020, Federal Minister for Economic Affairs Peter Altmaier announced an ambitious expansion path for wind and solar energy for the first quarter of 2021. After a long wait, there was only the famous drop in the ocean: four gigawatts of onshore wind energy and six gigawatts of photovoltaics are the targets for 2022. Longer-term expansion targets? Not a chance. Clearly, the need for a rapid transformation of our energy supply has not yet been recognised by the CDU/CSU, despite all their climate protection commitments during the election campaign."
The passive house turns 30 - pioneering work paves the way for energy efficiency worldwide The passive house celebrates its 30th birthday! The pioneering project started as an experiment by building physicist Prof Wolfgang Feist can take great credit for its success: When climate protection was only on the agenda for very few people, it paved the way for energy efficiency in buildings. Today, the passive house standard is being realised around the world, including in impressive flagship projects. Further reasons to celebrate: the 25th anniversary of the Passive House Institute and the anniversary edition of the International Passive House Conference.
To live up to its climate change pledge under the Paris Agreement, the European Union must ensure that all 250 million existing buildings, as well as all new buildings in the EU, produce near-zero greenhouse gas emissions. In a new report, European national academies of science, through their association EASAC, call for far-reaching policy action. "Policies have long focused on creating energy-efficient buildings that require less heating and air conditioning or generate renewable energy on site. However, the energy used to operate buildings is only part of the story. We need to broaden the scope and look at emissions from building materials and methods - both for new buildings and for building refurbishment," says William Gillett, Director of EASAC's Energy Programme.
G7 environment ministers issue far-reaching declaration: 1.5 degree limit takes centre stage - progress also to be made on international climate financing before the World Climate Summit
For the mayors of German cities, climate protection and mobility remain the most important topics despite the pandemic. The OB-Barometer 2021 of the German Institute of Urban Affairs (Difu) shows a clear trend change in the topic of inner city development, which is gaining strongly in importance.
In a recently written short study, scientists from the Department of Energy System Analysis at the Fraunhofer Institute for Solar Energy Systems ISE prepared an evaluation of the Market Master Data Register (MaStR) and the EEG system master data for photovoltaics (PV). Important findings of the analyses were that with 38 percent of the newly installed capacity, the increase in capacity in Germany is increasingly taking place in the segment of rooftop systems larger than 100 kW, 22 percent of the newly built PV systems are erected in a west, east or east-west direction and 19 percent of these systems have tilt angles smaller than 20 degrees.

The KfW programme "Energy-efficient urban refurbishment" promotes integrated energy-efficient neighbourhood concepts and refurbishment management with programme part 432. Programme parts 201 and 202 provide investment support for cross-building and infrastructural supply systems. The Federal Ministry of the Interior, for Building and the Home Affairs provides the funding for the energy refurbishment process from the individual building to the neighbourhood from the Energy and Climate Fund (EKF).
European Green Deal offers opportunities for investments in emission-intensive basic industries - Clear political framework must ensure that investments are also cost-effective and incentivised - Introduction of CO2 contracts for difference and reform of EU emissions trading essential.
Storms, drought and insect infestations have caused a great deal of damage to Germany's forests over the past three years. The "International Day of Forests" on 21 March is a good time to become aware of the many services provided by the forest.
"The raw material wood is precious. It is therefore important to use it responsibly and in a way that conserves resources," warns Peter Aicher, Chairman of Holzbau Deutschland. Even if wood is affected by environmental influences or the bark beetle, it does not represent an inferior raw material, but has almost identical properties to conventional construction timber. "If the so-called 'calamity wood' has the same structural quality in terms of load-bearing capacity as conventional sawn timber, it can be used without restrictions," explains Aicher. In addition, the wood retains its important function as a CO2 sink, regardless of external impairments.
