In contrast to combustion engines, the amount of energy required to manufacture the batteries plays a greater role in electric cars. According to the Heidelberg IFEU Institute, one kWh of battery capacity can save around 125 kg of CO2-emissions. The production of an electricity storage system with 24 kWh therefore produces around three tonnes of CO2 emissions. In contrast, the emissions produced when building an electric motor are lower. As a result, the e-car has to reduce its driving emissions by around 2.74 tonnes of CO2 offset. This means that if we concentrate too much on the emission of greenhouse gases, we could end up reducing CO2-The overall balance of a product should not be lost sight of. The latest, most economical model is not always the best choice and the frugal use of an existing product is the better way. In short, a vehicle should not be purchased as long as the CO2-backpack has not been emptied.
Dwindling raw materials, dwindling landfill space and ambitious climate protection targets make it essential to overcome the high use of resources in the construction industry. The film shows that there are already many ways to use building materials sustainably in the cycle: Recycled concrete, recycled gypsum, the reuse and recycling of bricks and the renewable raw material wood.
Around 60 percent of the resources used in Berlin are processed in the construction industry. This contrasts with millions of tonnes of building rubble and construction site waste. Every year, 2.2 million tons of primary raw materials are already saved in civil engineering and building construction in Berlin through the use of quality-assured secondary raw materials. But Berlin does not intend to stop there. By 2030, a further 1.4 million tonnes of primary materials are to be replaced by secondary raw materials each year.

Frankfurt/Main (dpa) - The Frankfurt "Rent Decision Alliance submitted around 25,000 signatures to the electoral office on Tuesday. The participants want to achieve a referendum on the preservation and expansion of subsidized housing, as spokespersons for the alliance said before the handover.
The administration must now check whether the necessary quorum - the required number of signatures - has been reached and whether a citizens' petition is admissible. According to its own information, 42 organisations belong to the alliance, including the district association of the Left Party, the Asta of the Goethe University, Attac and several housing and urban policy initiatives.
They have three demands: The city-owned housing company ABG should only create subsidized housing; all tenants entitled to social housing should pay a maximum of 6.50 euros per square meter; prices per square meter of a maximum of 6.50 euros should apply in two-thirds of all ABG apartments that become vacant.
Forest Minister Peter Hauk MdL: "With our call for ideas, we want to further promote municipal timber construction in the state and further consolidate our nationwide position as the No. 1 timber construction state".
A total of around 6.5 million euros in funding from the Baden-Württemberg timber construction campaign is available for the call for ideas for municipal timber construction concepts.
The online application deadline is February 12, 2020.
"In view of the global climate development, there is no way around the increased use of wood as a renewable and climate-friendly building and insulation material. Only buildings with a high proportion of wood can store larger amounts of carbon over centuries. With our call for ideas, we want to further promote municipal timber construction in the state and further consolidate our nationwide position as the No. 1 timber construction state," said the Minister for Rural Areas and Consumer Protection, Peter Hauk MdL, in Stuttgart on Friday (13 November). The aim is to establish Baden-Württemberg as a model of climate-conscious building culture. As far as possible, the state's building projects would be implemented in timber and timber hybrid construction. Now the state is also supporting the municipalities in their development towards climate-friendly construction with wood.
"The call for ideas focuses primarily on municipal concepts and approaches in urban development that lead to the implementation of timber construction projects. We are looking for new innovative approaches, for example in our own properties, neighbourhood development or the creation of entire settlements", explained Minister Hauk. This requires committed and innovative municipalities that lead the way as trendsetters. The ideas competition is intended to provide incentives for this. "Those who build with the renewable raw material wood protect the climate and strengthen regional economic cycles. The timber and mixed timber construction methods are ideal, for example, for adding on to existing buildings, closing gaps between buildings or renovating existing buildings", explained the Minister. Numerous projects are already proving that high-quality and sustainable further development of urban and rural areas with wood is economical and brings added value for the population.
The state is therefore promoting greater climate awareness in the construction industry with the Baden-Württemberg timber construction offensive. Wood is the only relevant building material that has a favourable CO2-balance and achieves an immediate storage effect. Thanks to innovative processing with low energy consumption, wood is used in a wide variety of forms and can contribute to a sustainable building culture with architectural accents.
Background Information:
Municipalities are invited to submit approaches to planning and building with wood in building construction. These can be initial ideas that must be assigned to one of the following four categories:
1. development and conception of the construction and renovation of own properties,
2. instruments and approaches of urban planning / development,
3. information, advice and education of those willing to build by the municipalities (communication)
4. other/special route.
The submission of ideas for the planning of individual objects, as well as neighbourhood and settlement approaches, consulting and qualification offers (internal and external), communication strategies and public relations, but also other formats in the municipal planning context are conceivable.
The call is designed to be low-threshold in order to address many municipalities. In a two-stage application process, a rough concept is first submitted online in the form of a short idea sketch. After an evaluation by a group of experts, selected municipalities have the chance to deepen the project idea and prepare it for implementation. Financial support of up to 20,000 euros each is available for this (1st stage). After a positive evaluation, there is the possibility of receiving further funding of up to 400,000 euros in the second stage for the implementation of their project idea (2nd stage).
The deadline for submitting a short outline of ideas via the online application is 12 February 2021 (1st stage). Interested municipalities can find more information on the website of the Timber Construction Offensive at www.holzbauoffensivebw.de
