On 4 July 2019, the Bonn City Council had decided to support a resolution declaring a climate emergency. In doing so, Bonn joined other municipalities in affirming that climate protection must have the highest priority in municipal action. The administration has therefore developed a catalogue of measures in recent months with the participation of all departments.
Mayor Ashok Sridharan: "The declaration of a climate emergency must now be quickly followed by action! We have therefore deliberately chosen an approach that enables us to take direct action: The city administration can implement many of the developed measures directly and thus make an additional contribution to climate protection and climate adaptation itself. However, it must also be clear to all of us: The catalogue of measures does not yet provide an answer to how the city of Bonn can become climate neutral by 2035! There is still a lot of work ahead of us here."
The Lord Mayor announced that the role of the Environmental Office would be strengthened within the administration with the Climate Protection Control Centre. The environmental office is to receive more staff and be even more involved in decisions relevant to climate protection.
The proposal for the catalogue of measures is to be discussed in the first reading in the Council on 6 February and then referred to the Environment Committee on 12 March. In the meantime, the Bonn Climate Protection Advisory Council will also be involved in an advisory capacity.
The draft resolution on the "climate emergency" also contains proposals from the Council mandate "Implementation of climate measures". In accordance with the mandate, they are based on the projects of the Integrated Climate Protection and Climate Adaptation Concept from 2013 that have not yet been implemented.
As far as possible at this point in time, the ideas are provided with costs and the possible CO2 savings. Financial incentives for climate-friendly actions are an important instrument in the entire portfolio of measures. For example, those who do not use disposable materials at events or want to install a PV system on their building or green the roof and façade should receive more support.
According to the administration's proposal, five million euros should be included in the 2021/2022 double budget as start-up financing for the projects described. This will enable some measures that have already been designed to be implemented immediately. For others, in-depth planning can be financed from this budget and the investment funds required for implementation can be assessed. These funds must be taken into account in the coming municipal budgets.
City Planning Officer Helmut Wiesner: "Climate protection has a history in Bonn since 1995. We can therefore build on the experience of 25 years and the established structures to face the increasing challenges of climate change. The action-oriented proposals for measures in response to the declaration of a climate emergency build on this." In total, the current programme comprises around 150 individual projects, which can be assigned to the following six fields of action.
Photovoltaics in Bonn is to be further expanded. The solar roof cadastre in Bonn already provides orientation for homeowners as to whether their own building is suitable for the installation of a PV system. Based on this, the city would like to start an advisory service to accompany interested parties from the initial information to the installation of the system. In addition, the "1000 Roofs Program" is to be launched as a subsidy program with a grant of 1000 euros per subsidized PV system.
In addition, where the city can exert influence, the installation of PV systems is to become mandatory for developers, for example in the case of new buildings within the framework of project-related development plans, development measures and the sale of municipal land. Following the example of the city of Tübingen, developers should have to prove that the installation of a PV system is uneconomical in order to be exempted from the obligation.
The city itself wants to set a good example and continue to systematically capture the great potential of its own buildings. For new municipal buildings, the installation of photovoltaic systems is generally prepared and - if possible - implemented in cooperation with the municipal utilities or energy cooperatives. There are currently 63 systems on municipal buildings. PV systems with an output of 172,000 kilowatt hours per year (kWh/a) were already installed on the sewage treatment plants in Duisdorf and on Salierweg in 2009 and 2016. A system with an output of 75,000 kWh/a is currently being implemented at the Bad Godesberg sewage treatment plant.
A forum with regular events for players in the housing and construction industry is to expand and institutionalise experience in the field of climate protection and energy efficiency. A municipal campaign on the subject of environmentally compatible building materials is to specifically address planners, architects and building owners. The Bonn Energy Agency (BEA) already provides advice and public relations work on energy-efficient construction and renovation and recommends energy-efficiency partners, for example, who can provide support for renovation or new construction.
The KfW-55 standard for new municipal buildings is currently already subject to very high energy efficiency standards that exceed the legal requirements. These standards also apply to project-related development plans, urban development contracts and development measures, as well as to the sale of municipal land. For its buildings, the city also wants to examine whether certified sustainability standards (e.g. DGNB certification system) can be applied in principle for renovations and new buildings.
The administration will develop a concept on how the City of Bonn, including the municipal subsidiaries Bonnorange and Stadtwerke, can become climate neutral by 2035. For this, the emission of greenhouse gases must be drastically reduced and suitable compensation possibilities must be created.
One thing is certain: In future, business trips are to be organised in a more climate-friendly way. Public transport has clear priority; air travel - especially within Germany - is to be avoided. The job ticket is to be made cheaper, and the city's fleet of e-vehicles is to be continuously expanded. The procurement of office equipment and uniforms is to be carried out according to climate and resource-friendly criteria. The city administration has also been using recycled paper for many years and has already received ten awards for this as one of the most recycling-friendly cities in Germany.
The state of North Rhine-Westphalia approved the extensive "Emission-free city centre" funding project in November 2019. Over the next three years, cycle lanes will be expanded and mobile stations will be built in the city centre, which will spatially link various transport services such as public transport, car-sharing and cycle hire and thus make it easier to switch between modes of transport. In addition, further e-charging stations and bicycle parking garages are planned.
As part of the "Lead City" model project, the "Jobwärts" programme is currently establishing a company mobility management system for employers in the region.
Organizers who focus on sustainability are to receive financial incentives - for example, for the purchase of green electricity or the reduction of disposable plastic. At its own major events, such as Pützchens Markt or the Christmas market, the city wants to set a good example.
Various actions are also intended to trigger a rethink among the population: Proposals include a car-free day and artistic productions that draw attention to the progressing climate change. The city's climate protection campaign "Think new, act simple" is to be expanded and campaigns such as city cycling are to be continued. As part of "Bio-Stadt Bonn", the city has been emphasising the topics of nutrition and organic farming since 2019.
In order to prepare as well as possible for the unavoidable consequences of climate change, precautions must be taken now. "Mobile green rooms" with vertical greenery and a leafy roof are to provide more quality of stay in the city centre on hot days. In addition, financial incentives and advice are to be offered to citizens who want to green their roofs and facades or sealed surfaces.
The climate analysis developed within the framework of the ZURES project and the planning information map based on it serve as an important basis in this context and provide information on how the increasing heat load can be countered with urban planning measures.

Results: When analysing the total annual costs, the running costs and revenues in the utilisation phase are taken into account in addition to the capital-related investment costs. The result of this full cost calculation is a relatively homogeneous cost level for all building energy standards examined. Due to the subsidies for the better standards, lower energy costs and the use of subsidies, the cost level remains relatively constant among the building energy standards. Thus, higher building energy standards up to the "KfW 40 Plus Standard" are already economically attractive today.
The influence of building energy standards can be classified as subordinate when considering total consumer spending.

From September, UrStrom eG will offer its e-car sharing users a customer-friendly cooperative booking app. The goal is a common e-car sharing platform for energy cooperatives throughout Europe.
Mainz, 23.08.2019 Select, book and open electric cars with your smartphone. These are the functions of the cooperative booking app "e-Carsharing in Bürgerhand", which the UrStrom BürgerEnergieGenossenschaft in Mainz is the first German energy cooperative to use. "The smartphone becomes the car key," says Klaus Grieger, project manager for electromobility at UrStrom eG. The four-language booking app has already been in use for some time at energy cooperatives in Belgium and Spain. "The app is extremely practical," says Klaus Grieger enthusiastically.
After UrStrom eG, other energy cooperatives in Rhineland-Palatinate will use the booking app. "We first want to optimise the app regionally for use in Germany so that we can then attract energy cooperatives throughout Germany to use the joint platform," says Dr Verena Ruppert, Managing Director of Landesnetzwerk Bürgerenergiegenossenschaften Rheinland-Pfalz e. V. (LaNEG) e.V. There are currently eight energy cooperatives working in LaNEG's e-car sharing working group that want to launch local e-car sharing projects or are already doing so. Energy cooperatives can also use the cooperative app to offer companies and municipalities needs-based e-carsharing solutions. The booking platform is the first step towards establishing the cooperative brand "e-Carsharing in Bürgerhand" throughout Germany.
At the end of 2018, citizen energy cooperatives from four European countries founded The Mobility Factory (TMF) as an umbrella cooperative of European e-carsharing cooperatives. TMF provides a professional e-carsharing platform to its members. Currently, all TMF members can use the booking app as licensees and participate in the further development of the system. In the future, the entire value chain in e-car sharing will be in the hands of the cooperatives and thus be user-oriented and independent of purely profit-oriented corporate structures. "The use and further development will remain in the hands of citizens, in the democratic structures of cooperatives," says Michael König, Chairman of TMF.
Currently, about 100 electric vehicles are in use at member cooperatives in Spain, Belgium, the Netherlands and Germany. In three years, there should be at least 1800 vehicles available to all users of cooperative e-car sharing across Europe.

Building culture is becoming a recognised goal in the real estate industry: with support from the real estate and housing industry, the Institute for Corporate Governance in the German Real Estate Industry (ICG) and the Federal Foundation for Building Culture initiated and developed the Code for building culturea voluntary commitment for the responsible performance of tasks by companies in the real estate industry.
In its role as project developer, planner, builder, owner, etc., the real estate industry bears particular responsibility for the design of our living spaces. At the same time, building culture values and social acceptance form the basis for economic success. The Codex for Building Culture now supports companies in the real estate industry in assuming social responsibility for the consequences of real estate business activities and for the built results on their own initiative and within the framework of self-regulation. The fact that building culture offers added value for the real estate industry has now entered people's minds - but is not always put into practice. In the survey of the participation process for the code, for example, 98% of the companies surveyed stated that the appreciation of historic properties is seen as relevant or at least relevant to a certain extent - only half of the respondents, however, stringently implement this in practice.
Building culture is always closely linked to process quality, which is why the initiators of the Code for Building Culture were keen to involve the players in the real estate industry in the drafting process. Since a personal discussion of the contents was not possible due to the Corona pandemic, companies in the real estate and housing industry were asked in the summer of 2020 to provide feedback on the draft of the Code for Building Culture by means of an online survey and were thus involved. Scientific support was provided by IREBS at the University of Regensburg.
Prof. Dr. Sven Bienert, Chairman of the Institute for Corporate Governance in the German Real Estate Industry /IREBS Institute at the University of Regensburg, is in favour of this code because: "In times of rising land prices and ever higher building densities, the issue of a "good building culture" is becoming increasingly important. This form of social responsibility will also increasingly concern the real estate industry in the future in the ever more important after-use and conversion - for example of churches that are increasingly coming onto the market."
"Our goal is to make the real estate industry fit for the future," says Karin Barthelmes-Wehr, Managing Director of the ICG. "This includes encouraging the players in the industry to deal with all the requirements of ESG (Environment Social Governance) and to forge new alliances in this regard. For this, the Code for Building Culture we have presented provides a very good basis in the field of planning, development and construction."
Reiner Nagel, Chairman of the Board of the Federal Foundation for Building Culture, emphasises: "The Code for Building Culture now focuses on the responsibility of real estate business activities for the spatial impact of the built environment on us and the resulting consequences, with which companies grow in their building culture competence. As a result, the quality of the built environment benefits from the Code for Building Culture that is now available."
The complete "Code forBuildingCulture" and documentation of the participation process can be found at on our website. It contains the following demands (abbreviated).
Attitude and Values:
- Holistic building culture
- Prudent action in new construction and portfolio development
- Appreciation of already existing building culture
