Description: Since plastics degrade very slowly, they remain in the environment on much longer timescales than most natural organic substrates and provide a novel habitat for colonization by bacterial communities. The spectrum of relationships between plastics and bacteria, however, is little understood. The first objective of this study was to examine plastics as substrates for communities of Bacteria in estuarine surface waters. We used next-generation sequencing of the 16S rRNA gene to characterize communities from plastics collected in the field, and over the course of two colonization experiments, from biofilms that developed on plastic (low-density polyethylene, high-density polyethylene, polypropylene, polycarbonate, polystyrene) and glass substrates placed in the environment. Both field sampling and colonization experiments were conducted in estuarine tributaries of the lower Chesapeake Bay. As a second objective, we concomitantly analyzed biofilms on plastic substrates to ascertain the presence and abundance of Vibrio spp. bacteria, then isolated three human pathogens, V. cholerae, V. parahaemolyticus, and V. vulnificus, and determined their antibiotic-resistant profiles. In both components of this study, we compared our results with analyses conducted on paired samples of estuarine water. This research adds to a nascent literature that suggests environmental factors govern the development of bacterial communities on plastics, more so than the characteristics of the plastic substrates themselves. In addition, this study is the first to culture three pathogenic vibrios from plastics in estuaries, reinforcing and expanding upon earlier reports of plastic pollution as a habitat for Vibrio species. The antibiotic resistance detected among the isolates, coupled with the longevity of plastics in the aqueous environment, suggests biofilms on plastics have potential to persist and serve as focal points of potential pathogens and horizontal gene transfer.

Description: Die Bundesregierung hat den Kohleausstieg bis zum Jahr 2038 beschlossen und beschleunigt so die Transformation in den Kohleregionen. Die Ausgangslagen für den Wandel in den Revieren und umliegende Gemeinden der Lausitz und des Rheinlands sind dabei sehr unterschiedlich. In beiden Regionen stehen Politik, Zivilgesellschaft, Wirtschaft und Wissenschaft vor der Aufgabe, Lösungspfade und Transformationskorridore zu finden, die ökologisch verantwortlich, sozial gerecht, wirtschaftlich vielversprechend und demokratisch getragen sind. Das IASS Potsdam veranstaltete im Frühjahr 2020 gemeinsam mit dem Kulturwissenschaftlichen Institut Essen einen Workshop, um demokratiepolitische Gemeinsamkeiten und Unterschiede im Strukturwandel der Braunkohleregionen herauszuarbeiten. Die Zwischenergebnisse werden in dieser Studie dargestellt.

Description: This IASS study takes an in-depth look at Covid-19's impacts on the global energy sector, and then zooms in to the country level to see individual country effects and responses. The case studies are compiled by energy researchers in Argentina, China, Germany, India, Israel, and the United States.

Description: This Discussion Paper discusses the implications of the European Green Deal and the Circular Economy Action Plan for plastic and packaging waste. According to a recent report, each European Union (EU) inhabitant generated 172.6 kg of packaging waste in the year 2017, 19% of which was made of plastic. Amid growing concerns about the environmental effects of such consumption habits, the regulation of packaging waste and plastic has moved to higher up the legislative agenda of the EU in recent years.

Description: This summary for decision makers is based on the report ‘Ecological Baselines of the Southeast Atlantic and Southeast Pacific – Status of Marine Biodiversity and Anthropogenic Pressures in Areas Beyond National Jurisdiction’ and provides consolidated information on key biological and ecological features of Areas Beyond National Jurisdiction (ABNJ) in the Southeast Atlantic as well as highlights key pressures placed upon it by human activities. ABNJ include the water column (the high seas) and the seabed (the Area) outside of the Exclusive Economic Zone (EEZ) of coastal States and cover about half of the Earth’s surface. This summary is intended to inform relevant actors and stakeholders to support their understanding of the function and importance of marine biological diversity in ABNJ and the need to for appropriate conservation and management measures. The report was prepared as part of the Strengthening Regional Ocean Governance for the High Seas (‘STRONG High Seas’) project – funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) through the International Climate Initiative (IKI).

Description: This report explores how the co-benefits of renewable energy and energy efficiency saving measures can play an active role in connecting the Mexican energy transition with key processes and commitments for development that have been determined by the country itself. These include the National Development Plan (NDP) for 2019-2024 as well as climate goals or Nationally Determined Contributions (NDC), to which Mexico is committed under the Paris Agreement. This study, published in conjunction with the project Enhancing the Coherence of Climate and Energy Policies in Mexico (CONECC), offers quantitative evidence of the co-benefits of two routes (scenarios) for energy transition as related to the Energy Transition Law (LTE). These vary in scope however, revealing how the co-benefits of renewable energy and energy efficiency can help to play an active role in achieving national development goals.

Description: How can science and business help build sustainable societies? This question took centre-stage at the second Global Sustainability Strategy Forum (GSSF), held on 22 - 24 March 2020. The event did not take place in Bangkok as previously planned due to the coronavirus pandemic. Instead, 25 leading experts from business and sustainability science came together online to discuss how the two sectors could work together more effectively.

Description: Der Bericht stellt die Resultate einer multikriteriellen Bewertung verschiedener Szenarien eines Kohleausstiegs in Deutschland vor. Die exemplarischen Politikszenarien basieren auf unterschiedlich umfassenden politischen Maßnahmenbündeln und bewegen sich im Spannungsfeld zwischen Ordnungsrecht und Markt. Der transdisziplinäre Bewertungsprozess wurde parallel zur Kohlekommission im Rahmen des Kopernikus-Projektes „Energiewende-Navigationssystem“ (ENavi) erprobt. Hierbei schätzten die Wissenschaftlerinnen und Wissenschaftler des Konsortiums die Folgen der Maßnahmenbündel ab und bewerteten diese anhand von zehn Nachhaltigkeitskriterien. Die so entstandenen Bewertungsvorschläge wurden mit Stakeholdern aus Zivilgesellschaft, Industrie, Wirtschaft und Politik geprüft, diskutiert und verfeinert. Der Bericht gibt einen Überblick zu Prozess, Methodik sowie Ergebnissen der Bewertung. Zudem zeigt er, unter anderem anhand eines Vergleichs mit der Kohlekommission, Verbesserungspotentiale des realisierten Bewertungsverfahrens auf. Die Erfahrungen, Empfehlungen und identifizierten Forschungsbedarfe bieten wertvolle Gestaltungshinweise für zukünftige Projekte mit einer ähnlichen inter- und transdisziplinären Herangehensweise.

Description: This report provides guidance to decision makers in all types of public and private organizations involved in the planning and development of CCU. It is prepared within the scope of the CO2nsistent project funded by the Global CO2 Initiative and EIT Climate-KIC, and is based on the published TEA and LCA Guidelines v.1. This report provides user-centered guidance on how to commission and understand TEA and LCA studies for CCU, and how to determine whether existing studies are eligible to be used in a decision making process. Another primary goal of this report is to ensure that disciplinary expertise is effectively taken up by decision makers and all potential audiences. The remainder of this document is structured in two parts. Part A introduces the reader to the concept of TEA and LCA studies: What types of input can such assessments provide for decision making? What are the limitations of their explanatory power? This part focuses on the goal and scope definition for such studies, and on other aspects that are particularly relevant for decision making. The document presents how the decision maker (or commissioner) and the assessment practitioner can jointly set the various assessment phases. These terms are explained in the boxes below. The approach and main components of TEA and LCA studies are described, with the specific goal of making the most sensitive disciplinary concepts clear and comprehensible to all audiences. Part B consists of practical tools to guide actors interested in commissioning TEA and LCA studies, and to support decision makers when evaluating and assessing TEA and LCA studies submitted by third parties. A series of consecutive steps, displayed as decision trees, provide support for checking the completeness of key aspects and requirements of TEA and LCA studies.
