Klaus Dosch (Faktor X Agentur + ResScore GmbH) presents the Resource-Score, a pragmatic and generally understandable label for resource- and climate-friendly building.
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 German Climate Protection Act (KSG) provides for a 65 per cent reduction in climate-damaging emissions by 2030 compared to 1990. By 2040, emissions are to be reduced by 88 percent and net greenhouse gas neutrality is to be achieved in 2045. To this end, the KSG sets annual reduction targets by 2030 for the individual sectors. The latest projection report of theUBAfrom 2021 has shown that with the currently planned climate protection instruments, both the climate targets in 2030 and the annual savings targets will be missed.
UBA's cross-sectoral CIS-2030 now shows which concrete instruments the individual sectors can use to achieve their annual savings targets by 2030 after all. With price instruments, support programmes and new and stricter legal regulations, the course can be set at an early stage to achieve the legally prescribed savings.
In the transport and building sectors, for example, significantly greater efforts will be needed in the future to reduce greenhouse gas emissions in the coming years. The climate protection instruments used in the model calculation in these sectors only fulfil the minimum requirements. In the case of transport and buildings, the prescribed targets will probably not be met, even with a mix of very ambitious instruments and measures. In order to achieve the interim targets on the path to 2030, additional instruments that are effective in the short term would therefore be necessary.
At the same time, the HIS-2030 shows concrete options for action with which the sectoral climate targets can still be achieved: The measures described in theScenarioThe predominantly economic instruments modelled in the transport sector should be flanked by a comprehensive expansion of rail transport and a strengthening of the environmental network of primarily buses and trains.
The KIS-2030 is based on instruments similar to those currently under political discussion - such as mandatory municipal heating planning or the minimum efficiency standards for buildings currently under discussion at EU level. The KIS-2030 also assumes a ban on new monovalent oil (from 2023) and gas boilers (from 2025), which goes beyond the current government drafts for the Building Energy Act.
Based on the scenario, it is recommended for the industrial sector to use subsidies for CO2-and -free technologies. Support programmes should be designed in such a way that they do not lead to negative environmental effects due to incorrectly set framework conditions or incentives.
The ADFC cycling club is a supporter of the Fridays For Future movement's global climate strike and is calling on all cycling sympathisers, members, supporters and regional groups to take part in the strike from 20 September.
According to the ADFC, the climate goals can only be achieved with a traffic turnaround in favor of car alternatives and a tripling of cycling. Groups of ADFC and Fridays For Future are planning joint actions in numerous cities.
Rebecca Peter's, ADFC deputy federal chairwoman, said: „The transport sector has so far not contributed at all to achieving the climate and sustainability goals. On the contrary, our cities are becoming more and more crowded, stressful, dangerous and dirty. However, climate-friendly mobility does not mean joining forces now to put 47 million e-cars on the roads and continuing to provide every conceivable incentive for people to travel even absurdly short distances by car. We need highly attractive offers for cycling and walking in combination with a top-developed public transport system - and much less car traffic to secure the quality of life in cities and the countryside!"
Request to the Climate Cabinet: investment boost
Specifically, the ADFC is calling for the implementation of the measures drawn up by the transport commission "National Platform for the Future of Mobility" in the spring. In order to increase the cycling mode share from the current meagre eleven per cent to the Dutch level of at least 25 per cent by 2030, nationwide, continuous cycle path networks, fast cycle routes for commuters and freight transport and many millions of bicycle parking spaces at train stations and public facilities must be built. By optimising the expansion of cycling, up to 13.5 million tonnes of CO2 must be saved. The Federal Government's Energy and Climate Fund must provide at least the 900 million euros per year estimated by the Transport Commission for this purpose. Peter's: "Germany can only achieve the climate targets in the transport sector if the potential of cycling is properly utilised. This potential will not unfold by itself, as the infrastructure has so far tended to discourage cycling. We need an immediate federal programme to finance inviting cycling infrastructure for everyone!"
...and more space for your bike
A new distribution of road space is essential for the climate-friendly transformation of transport. Until now, cars have occupied the lion's share of space in cities. The ADFC is calling for half of the road space to be used for mobility without cars. Peter's"It's not enough to put more money into the system. Wide, safe cycle paths first and foremost need space from car traffic. The federal government must give local authorities far-reaching options in traffic law to actually create this space."
Joint campaigns in many cities
In many cities, including Berlin, Bergisch-Gladbach, Bonn, Gelsenkirchen, Hanover and Munich, ADFC groups are taking part in the global climate strike under the slogan #MehrPlatzFürsRad or #CyclistsForFuture. In Bad Kreuznach, Esslingen, Frankfurt, Heidelberg, Karlsruhe, Mainz and Nuremberg, ADFC groups are temporarily converting car parking spaces into cycle lanes, street cafés or bicycle parking spaces as part of the international ParkingDay.
Berlin, 9 January 2020 - One of the Herculean tasks in achieving the climate targets is to radically reduce CO2 emissions from the heating supply. A research group led by the Institute for Ecological Economy Research (IÖW) is showing how cities can move away from coal, oil and gas in a socially responsible way. The "Urban Heat Transition" project analysed possible contributions from renewable energies and local heat sources in Berlin's urban districts. "Waste heat from businesses, heat from waste water or geothermal energy have hardly been utilised to date. The key to such environmentally friendly heat are neighbourhood concepts and heating networks," says project manager Bernd Hirschl from the IÖW. "An important prerequisite is a more efficient building stock. Only if the heat demand is significantly reduced can environmentally friendly heat sources be utilised efficiently."
In the three-year project, the project team from the IÖW, the University of Bremen and the Technical University of Berlin worked together with the Berlin Senate Department for the Environment, Transport and Climate Protection with funding from the Federal Ministry of Education and Research to develop local heating concepts for three Berlin neighbourhoods. At the end of 2019, they discussed their results with the heating industry in Berlin, and the documentation of the conference is now available online at www.urbane-waermewende.de.
Developing nuclei for the heat transition
"Previous neighbourhood concepts were often too complex, had too many different stakeholders and often ended up in a drawer. That's why we recommend a nucleus approach," says Elisa Dunkelberg from the IÖW. These could be public buildings, new construction projects, commercial buildings or housing associations and co-operatives.
The researchers show what a neighbourhood concept can look like for an old building district in Charlottenburg-Wilmersdorf: Firstly, the heat demand must be reduced through energy-efficient refurbishment. The heat can be generated using a wastewater heat pump, which is partly powered by solar electricity generated on site, in combination with combined heat and power generation. "Particularly in the case of public buildings, which have a pioneering role - enshrined in law in Berlin - it should always be checked in the case of refurbishment and new buildings whether they are suitable as a nucleus for a neighbourhood concept and the co-supply of surrounding buildings," emphasises Dunkelberg.
Climate-neutral district heating: utilising waste heat and renewables
District heating plays a major role in urban areas. "To become climate-neutral, it is important to integrate more local heat sources from wastewater, river water and geothermal energy as well as waste heat into district heating," says Hirschl, adding that attention must also be paid to the resilience of the heat generation system. A joint case study with the Neukölln district heating plant shows that it is possible to utilise local heat sources. But it needs to be tested technically and requires supporting financial measures. The next steps should now be test drilling for deep geothermal energy, for example, as well as pilot plants that use large heat pumps to provide wastewater or river water heat for district heating. Strategies for funding and risk protection are needed for investment in these technologies, some of which are untested and highly expensive.
Heat transition requires municipal strategic heat planning - and social compatibility
"Municipal heat planning, which has long been standard practice in pioneering countries such as Denmark and in other federal states and municipalities for some time, helps to tap into the identified potential," emphasises Hirschl. The basis for this is a heat register that visualises heat sources such as waste water and commercial waste heat. This can also be used to identify neighbourhoods for cross-building concepts. With sector coupling, it is also important that local authorities and cities plan across infrastructures. Instruments such as urban land-use planning and urban development contracts must be geared towards climate neutrality.
Low refurbishment rates in recent years show that purely incentive-based measures are not enough to ensure energy modernisation. The researchers therefore recommend implementing the regulations more strongly and developing a step-by-step plan to guide the building stock towards climate neutrality. At the same time, subsidies must be increased and conditions for passing on rent must be made more socially acceptable. A step-by-step plan under the conditions of a rent cap must be designed in such a way that energy modernisation is economically reasonable for both landlords and tenants.
Federal Ministry of Education and Research funds "Urban Heat Transition" project for another two years
The Federal Ministry of Education and Research is funding the project in a new partner constellation for a further two years in order to test solution strategies for the central obstacles to implementation and to anchor the research results in municipal heat planning. In addition to the IÖW, the partners are Berliner Wasserbetriebe and the law firm Becker Büttner Held.

Current timber engineering at a glance
There are many reasons for and advantages to building with wood compared to conventional construction methods: Wood is a renewable building material and, as a CO2 sink, helps to protect the climate. At the same time, thanks to modern calculation and production methods, it can be used for numerous construction tasks. Wood has excellent structural and indoor climate properties and can be easily combined with all other common building materials.
Based on 24 international projects, this specialist book provides an overview of the variety of possibilities currently realised in modern timber construction. In texts, images and plans, the contributions document both the architectural and structural qualities of contemporary timber constructions, from the design planning to the supporting structure right down to the last detail.
