Already in December, the state parliament, with the votes of the red-red-green coalition, had a decision The state has adopted a resolution on how it intends to implement the 2030 Agenda for Global Sustainable Development and the United Nations Framework Convention on Climate Change on the ground.
For the first time ever in a federal state, the state parliament in Erfurt is thus also setting up a "Parliamentary Advisory Council on Sustainable Development". Some federal states have their own sustainability councils or scientific advisory bodies, and many have also formulated their own sustainability strategy. However, there is no advisory council at parliamentary level anywhere.

In Troisdorf, North Rhine-Westphalia, the largest tenant electricity project in Germany is currently running with subsidised funding from the so-called tenant electricity surcharge under the Renewable Energy Sources Act (EEG). The project, which was supported by EnergyAgency.NRW following an initial consultation, supplies 24 social housing apartments in three multi-storey buildings with a total of 75 residents with electricity. For this purpose, all roof surfaces were covered with photovoltaic modules with a total output of 86.9 kWp. The PV system is completed by six Powerwall 2 battery storage units from Tesla. "The tenants have committed 100 per cent to the project. In addition, the PV electricity, insofar as it is not consumed by the water-to-water heat pump or the tenants, is first stored in electricity storage units. This works so efficiently that we already reached an average self-sufficiency level of 83 percent in May. On isolated days and nights, even 98 percent," explains Frank Scholzen from Scholzen Immobilien, the company that owns the properties.
In rental electricity projects, electricity is generated in a rented property - by PV and/or combined heat and power (CHP) units. This direct electricity is often sold by the operator of the plant to the local energy supplier or - as in Troisdorf - by the landlord to the tenants. "The electricity offered to the tenants is cheaper than electricity from the grid. The advantage for the system operator is an additional income opportunity, as well as an ecologically sustainable electricity supply," explains Wilhelm Schröder from EnergyAgency.NRW, who accompanied the project in an advisory capacity.
However, the three buildings of Scholzen Immobilien are not only characterised by an innovative power supply, Troisdorf is also future-proof in the area of heat: The heating system consists of two water-water heat pumps with a combined thermal output of 76 kW. The well depth is only 14 metres - thanks to the high groundwater level not far from the Rhine. Scholzen: "The smart meters supplied by the Aachen-based company Discovergy enable continuous monitoring of the energy flows between the PV system, heat pump, energy storage and main meter."
In this complex and demanding project, many parties have to be coordinated. In Troisdorf, the following were involved:
Priogo AG from Zülpich (specialist partner for photovoltaics, heating technology, electromobility)
Discovergy GmbH from Aachen (smart metering systems)
Stadtwerke Troisdorf GmbH (distribution system operator)
Westfalen Group from Münster (residual electricity supplier)
Vaillant Group from Remscheid (manufacturer of the heat pumps) and Geotechnik GmbH from Wesseling (well drilling company)
In the meantime, the company Scholzen Immobilien is planning another tenant power project in Düsseldorf.
By the end of April 2018, a total of 19 tenant power projects subsidised under the EEG with an installed capacity of more than 350 kWp had been realised in NRW. The EnergyAgency.NRW has published a brochure entitled "Mieterstrom - kurz erklärt" (Tenant Electricity - Explained in Brief), which presents in detail the technical and legal aspects that need to be considered when implementing projects.
How can Bonn become climate neutral by 2035? This is the question that the participatory project "Bonn4Future - We for the Climate!" would like to discuss together with Bonn citizens over the next two years. Since mid-2019, the climate emergency has been in effect in Bonn; in November 2019, the Council decided that Bonn should become climate neutral by 2035. The city and the non-profit association Bonn im Wandel have now signed a cooperation agreement and thus launched "Bonn4Future".
Very important in "Bonn4Future" is a new culture of mutual listening and good cooperation. All those involved are looking for solutions on how climate neutrality can succeed for our city. Everyone takes responsibility and makes their contribution.
"In order to achieve climate neutrality in Bonn by 2035, it is not only a question of setting the right course at international and national level, but also of all of us here on site," says Mayor Katia Dörner. "On politics, administration, companies and the people of Bonn with their ideas and decisions. We want to enter into dialogue with them in the participatory process 'Bonn4Future', because only in this way can this great transformation process for Bonn succeed. I am very much looking forward to working with Bonn in transition and our committed urban society!"
Project modules: Developing and implementing measures
At Climate Day - which will be scheduled and planned depending on the pandemic situation - citizens are invited to develop a joint climate vision and action plan for a climate-neutral Bonn. The ideas and findings from this Climate Day will flow into a total of four planned Climate Forums - The first is to take place in the first half of 2021. There, 100 randomly selected citizens will work together with experts from business, science, associations, culture, administration and politics to develop strategies and concrete proposals for the path to climate neutrality in 2035.
Results and ideas from the forums are reflected in the administration and in politics. They serve as orientation and support for the further development of the already existing catalogues of climate protection measures.
An Project Advisory Board and an accompanying scientific evaluation ensure a high quality of the participation process.
"Climate change is on people's minds in Bonn, we notice that every day in our work," says Dr. Gesa Maschkowski, board member of the Bonn in Transition association. "Many people want to do something and want effective measures. Now we bring them together. The citizens, people from business, science, culture and the social sector as well as politicians from all parties. Because we have to plan and act now if Bonn is to be climate neutral by 2035 at the latest."
The broadest possible participation should produce constructive ideas and results over the next two years. To kick off the process, citizens can already express their views today at the urban portalwww.bonn-macht-mit.de inform about the process and contribute their ideas on how to make the process work well.
Reaching the goal together
"Bonn4Future - Wir fürs Klima!" already received a lot of support from more than 50 Bonn initiatives before the official start of the project. However, it is important to the creators to bring people from all areas of the citizenry on board. The process is to be supported by all social groups.
An accompanying Communication and education concept is dedicated to building up a communication network. In this way, multipliers are won over and care is taken to ensure that "Bonn4Future" remains a topic of conversation and that many people are motivated to participate.
An important communication tool is also the city-wide, interactive Sustainability platform. It will make visible initiatives, activities and dates on the topic of climate-neutral city, commitment to sustainability and citizen participation in the context of the Sustainable Development Goals (SDGs).
Background
The cooperation agreement that has now been concluded was preceded by a citizens' application for participation in achieving the goal of climate neutrality. Bonn in Transition and the Climate Watch Bonn introduced this at the beginning of the year. In the meantime, the participation concept is supported by about 50 initiatives, companies and organisations. The citizens' committee agreed to it. Bonn im Wandel then developed a concept for the multi-stage procedure with the support of experts for citizen participation and further developed it in cooperation with the city administration.
With a resolution in September 2020, the Council of the City of Bonn finally commissioned the administration to conclude a cooperation agreement with Bonn im Wandel for the coordination and implementation of the two-year process. Funds of up to 719,000 euros will be made available for this until the end of 2022. The project will be implemented in the "Bonn4Future" project office. Here, four experienced experts for communication and participation work on 2.4 positions, supported by the Bonn in Change core team. On the part of the city administration the project is coordinated and accompanied by a half position. There is also a close connection to the citizen participation portal "Bonn macht mit". The participation portal bundles all information on participation offerings of the city of Bonn and provides opportunities for direct participation.
Bonn im Wandel sees itself as an ideas and project laboratory for a sustainable city. The association brings a large network as well as nine years of experience in the initiation and organization of civil society projects and change processes into the process.
