In diesem Bericht wird das Wohngebäudemodell der Abteilung Kreislaufwirtschaft des Wuppertal Instituts präsentiert. Der Bericht zielt darauf ab, die Materialströme, die durch Abriss, Neubau, Sanierung und Austausch im Wohngebäudesektor des Bundeslandes Nordrhein-Westfalen während des Zeitraums von 2022 bis 2060 verursacht werden, abzuschätzen. Das Modell verknüpft dabei Angaben zu tatsächlichen Wohngebäudezahlen, entnommen aus den Daten des Statistischen Bundesamts und der Zensuserhebung 2011, mit typischen Baumaterialien je Gebäudetyp und Baujahr. Die Gebäudetypologie basiert dabei auf Arbeiten des Instituts für Wohnen und Umwelt. Bis zum Jahr 2060 können so über Festlegung von Abriss-, Neubau- und Sanierungsraten sowie Austausch einzelner Bauteile mögliche Materialströme des Landes NRW im Wohnbausektor modelliert werden.
Fortschreitende Digitalisierung und zunehmende Internationalisierung von Märkten bergen Herausforderungen für Unternehmen mit traditionell geprägten Arbeits- und Fertigungsstrukturen. Um den steigenden Anforderungen gerecht zu werden, sollten in diesen Unternehmen die digitale Arbeitsfähigkeit und Kompetenzen für Agilität ausgebaut werden. Dieser Beitrag beschreibt die Konzeption einer digitalen Plattform zur Steigerung derartiger Kompetenzen in kleinen und mittelständischen Unternehmen (KMU). Die digitale Kompetenzplattform soll insbesondere produzierenden KMU strukturschwacher Regionen helfen, ihre Agilität zu steigern und so zur Innovations- und Zukunftsfähigkeit des Unternehmens beitragen.
Akzeptanz von industriellem CCS in Nordrhein-Westfalen : Empfehlungen für Politik und Industrie
(2023)
Für die Landesregierung Nordrhein-Westfalen (NRW) ist die industriell genutzte Kohlenstoffabscheidung und -speicherung (engl. industrial carbon capture and storage, kurz iCCS) ein zentraler Baustein für den Übergang zu einer klimaneutralen Industrie bis 2045. Dafür braucht es aber eine breite gesellschaftliche Akzeptanz - zumal Pläne zur CO2-Abscheidung bei Kohlekraftwerken vor über zehn Jahren schon einmal an mangelnder gesellschaftlicher Akzeptanz gescheitert sind. In diesem In Brief haben die Autor*innen die Ergebnisse von zwei durchgeführten Akzeptanzstudien zu iCCS in NRW zusammengefasst und diskutieren, welche Handlungsempfehlungen sich daraus ergeben.
Power-law city-size distributions are a statistical regularity researched in many countries and urban systems. In this history of science treatise we reconsider Felix Auerbach’s paper published in 1913. We reviewed his analysis and found (i) that a constant absolute concentration, as introduced by him, is equivalent to a power-law distribution with exponent ≈1, (ii) that Auerbach describes this equivalence, and (iii) that Auerbach also pioneered the empirical analysis of city-size distributions across countries, regions, and time periods. We further investigate his legacy as reflected in citations and find that important follow-up work, e.g. by Lotka (Elements of physical biology. Williams & Wilkins Company, Baltimore, 1925) and Zipf (Human behavior and the principle of least effort: an introduction to human ecology, Martino Publishing, Manfield Centre, CT (2012), 1949), does give proper reference to his discovery - but others do not. For example, only approximately 20% of city-related works citing Zipf (1949) also cite Auerbach (Petermanns Geogr Mitteilungen 59(74):74–76, 1913). To our best knowledge, Lotka (1925) was the first to describe the power-law rank-size rule as it is analyzed today. Saibante (Metron Rivista Internazionale di Statistica 7(2):53–99, 1928), building on Auerbach and Lotka, investigated the power-law rank-size rule across countries, regions, and time periods. Zipf's achievement was to embed these findings in his monumental 1949 book. We suggest that the use of “Auerbach–Lotka–Zipf law” (or "ALZ-law") is more appropriate than "Zipf's law for cities", which also avoids confusion with Zipf’s law for word frequency. We end the treatise with biographical notes on Auerbach.
Junge Menschen sehen sich durch die Klimakrise einer Einschränkung ihrer Entfaltungs- und Lebensmöglichkeiten gegenübergestellt. So überrascht es nicht, dass gerade die junge Generation sich aktiv für mehr Klimaschutz einsetzt - doch sind es wirklich alle Jugendlichen, die auf die Straße gehen? Die vorliegende explorative Studie zeigt auf, wie sowohl die Wahrnehmung der Klimakrise, die Handlungsmuster und auch die Verantwortungsattribution - individuell, innergenerational und politisch - milieuspezifisch verhandelt werden. Informiert durch das Projekt Schools4Future wurden vier Leitfadeninterviews mit Schüler*innen zur Wahrnehmung und Deutung der Klimakrise geführt. Im dreischrittigen Kodierprozess der Grounded Theory konnten Muster der Betroffenheit, der Verantwortungsattribution und der Handlungsstrategien von vier jugendlichen Klimaaktivist*innen aus akademischen und prekären Herkunftsmilieus rekonstruiert werden.
Die Bereitstellung industrieller Prozesswärme ist eine zentrale Herausforderung für ein zukünftiges klimaneutrales Energiesystem. In diesem Artikel wird die Vielfalt an etablierten und neuen Energieträgern und Technologien zur treibhausgasarmen bzw. -neutralen Bereitstellung von Prozesswärme vorgestellt. Zudem werden ihre wichtigsten Stärken und Schwächen skizziert, um daraus geeignete Anwendungsfelder und eine Priorisierung ihres Einsatzes zu identifizieren.
Nigeria is Africa's top cement producer and could be on course to be one of the top producers globally. The goal of this study is to identify and critically examine the pathways available to Nigeria to meet its decarbonisation goals in the cement sector. Based on a literature review, the study assesses demand drivers and decarbonisation potentials for the sector. It then presents two different quantitative pathways for growth in production of cement by 2050, and three different pathways for decarbonisation of the sector. Using published data and a scenario analysis tool, the study calculates how the sector's emissions might evolve under each of these pathways. The results indicate that, in the most ambitious scenario, emissions from the sector can plateau by the late 2030s, resulting in an overall increase of 21% by 2050 (compared to 2015 levels). Achieving this scenario is necessary in order to put the sector on a path to net zero emissions beyond 2050. The scenario is driven by reductions in both energy-related and process emissions, as well as a small share of carbon capture and storage and demand management. A moderately ambitious scenario that relies mostly on savings on energy-related emissions results in an 84% increase in emissions by 2050. Finally, the Business-as-Usual scenario results in an almost tripling of emissions by 2050. The results indicate a strong potential for policies to drive improvements in energy efficiency and clinker-to-cement ratio. Critical areas of uncertainty within the assumptions include the production rates (including the evolution of the export market) and the fuel mix.
Do ngân sách các-bon còn lại trên toàn thế giới đang giảm nhanh chóng, các quốc gia trên toàn cầu đang tìm kiếm các giải pháp để hạn chế phát thải khí nhà kính. Ngành công nghiệp sản xuất và sử dụng than là một trong những ngành phát thải nhiều các-bon nhất, do vậy, các khu vực khai thác than sẽ bị ảnh hưởng đặc biệt bởi quá trình chuyển đổi sang hệ thống năng lượng và kinh tế trung hòa với khí hậu. Tại các khu vực thực hiện chuyển đổi, những thách thức không chỉ tồn tại trong lĩnh vực sản xuất năng lượng, bảo vệ môi trường, mà còn ở các lĩnh vực kinh tế và xã hội - thường được biết đến với khái niệm "Chuyển đổi Công bằng". Các cấp ra quyết định ở các khu vực khai thác than rất cần có các công cụ hỗ trợ giúp họ xác định các giải pháp chuyển đổi, vừa giúp đa dạng hóa nền kinh tế, vừa hỗ trợ người lao động và cộng đồng địa phương. Viện Wuppertal mong muốn hỗ trợ nâng cao năng lực cho các khu vực khai thác than trên toàn thế giới thông qua Bộ công cụ Chuyển dịch Công bằng – một tài liệu tổng quát, minh họa những thách thức và cơ hội của quá trình chuyển đổi bền vững. Bộ Công cụ này bao gồm kiến thức về xây dựng chiến lược, đưa ra các khuyến nghị về quản trị quá trình chuyển đổi, thúc đẩy việc làm bền vững, nêu bật các lựa chọn công nghệ và đề cập tới vấn đề phục hồi môi trường, tái sử dụng các cơ sở hạ tầng sản xuất than. Bộ Công cụ này được xây dựng dựa trên các nghiên cứu của Viện Wuppertal trong khuôn khổ “Sáng kiến của Liên Minh Châu Âu về chuyển dịch tại các khu vực khai thác than” và các kinh nghiệm thực tế của một số khu vực khai thác than trên toàn thế giới.
Rising energy costs have led to increased discussion about the social impact of the energy transition in Germany in recent years. In 2021, a gradually increasing CO2 tax was introduced. This paper analyzes the question of whether a CO2 tax can be socially just. Using data analysis and desk research, correlations between income and energy consumption in Germany are shown. In a short analysis, it is investigated which additional burdens different types of private households have to expect in the coming years due to the introduction of CO2 pricing on energy. In particular, the introduction of a per capita flat rate fed by CO2 tax revenues could be a suitable way to reduce the burden on low-income households.
Case study on the German discourse of industry decarbonisation : a discourse network analysis
(2023)
The adoption of the Paris Agreement in 2015 and the passing of the Climate Action Law in Germany in 2019 established the legal need for the basic material industry in Germany to decarbonise. For the industry sector, the target is sets at a 49-51% GHG reduction by 2030 compared to 1990. Even though the sector specific targets are likely to become obsolete, a Hydrogen Strategy, Industry Strategy and Climate Protection Contracts are currently being developed or elaborated on. These are to further ensure and enable the basic material industry in Germany to decarbonise. These developments are emphasising the relevance of studying the industry decarbonisation at the time of conducting this research.
As the institutionalisation of the industry decarbonisation is influenced by discourse, the analysis of the discourse is an important tool for studying the power effects produced by and built into the discourse. This is the first research aiming to provide a structured analysis of the discourse on industry decarbonisation in Germany. Drawing on discourse analysis and the Multilevel-Perspectives framework, this research investigated the power and dominance of storylines to influence the discourse of the industry transformation towards decarbonisation. In this research insights were obtained into the storylines used in this discourse, the actors who are part of this discourse, the frequency of storylines used and the percentage of actors making use of these storylines. Additionally, insights were generated into the discursive network and potential coalitions.
This research made use of the Discourse Network Analysis software in combination with Visone and Excel for data collection, analysis, and visualisation. Based on 117 documents of various categories from the years 2012 to 2023, the discourse on German industry decarbonisation is discovered to be dominated by storylines of mainly technological or economic nature. The general sentiment discovered by the different actors is positive with the storylines focusing on establishing the conditions for the industry to decarbonise and no resistance being communicated. The discourse is furthermore dominated by most storylines. 18 out of 27 storylines are being used by more than 56% of all actors. The high overlap in storyline indicates discursive homogeneity. The homogeneity is further indicated through the lack of emerging discourse coalitions and the therewith connected lack of struggles for discursive dominance. One coalition can be defined with some actors being deeper involved and some being less involved in the discourse.
As decisions on the transition path for Germany's industry to decarbonise are still to be taken the lack of discursive struggles has come to my surprise. In the discussion I reflect on how the positive sentiment, the discursive homogeneity and the great number of dominant storylines may come about.
