As part of the CiBER project "Circular City Berlin - pathways from potential to implementation", initiatives and business models are being investigated that can contribute to the development of a next-generation circular economy in Berlin. The special focus is on the areas of construction, electronics and textiles. The next-generation circular economy is about innovations in product design and product use systems.

The innovation field of construction is a resource-relevant field in Berlin – in 2017, the construction sector accounted for about 22 percent of the raw material input of the state of Berlin. Currently, the recycling rate for mineral construction waste is around 50 percent, and is expected to increase to more than 60 percent by 2030. Circular economy approaches in the field of construction have to cover the entire life cycle: from the design of durable and deconstructable structures to the use-phase and material-preserving re-use to circular business models.

In the framework of the scientific accompanying research (PlastikNet) of the research focus "Plastics in the Environment – Sources • Sinks • Solutions" (Plastik in der Umwelt – Quellen • Senken • Lösungsansätze) Ecologic Institute coordinates 20 joint research projects, which deal with plastics in the environment funded by the Federal Ministry for Education and Research (Bundesministerium für Bildung und Forschung, BMBF). This fact sheet series condenses the joint research project findings and presents them consistently in the project design.

As part of the project "Drought and Water Use Conflicts in Germany (WADKlim)", Ecologic Institute developed a promotional flyer based on visual style and template of the German Environment Agency. The flyer contains relevant general information about the project – its theme, focus, aims, activities and contact information.

This schema shows the three functions of a fish protection system: blocking, guiding, transferring. The infographic is part of the fact sheet "What makes a screen to a fish protection screen? The functional components of a fish protection system."

This infographic shows the permeability for juveniles and adults of different fish species on 20- and 10 mm screens. The infographic is part of the fact sheet "What makes a screen to a fish protection screen? The functional components of a fish protection system."

This infographic shows the differences between horizontally angled and vertically angled fish protection screens. The infographic is part of the fact sheet "What makes a screen to a fish protection screen? The functional components of a fish protection system."

A fish protection system always consists of a fish protection screen and a bypass, designed as a functional unit. This infographic shows and explains the components. The infographic is part of the fact sheet "What makes a screen to a fish protection screen? The functional components of a fish protection system."

The central objective of the Hydromorphology IV Workshop was to exchange experiences and information and to identify and reflect on challenges of the administrative and practical implementation processes of watercourse development measures.

This study, co-authored by Raffaele Piria, analyzes energy industry and policy developments on hydrogen in the U.S. and develops an agenda for cooperation between Germany and the U.S. in this area. In addition to the foreign policy discourse, there are many opportunities for cooperation between Germany and the U.S. in the field of hydrogen.

Plastics are all around us and make up an essential part of our daily lives. How much do we know about this material, its variety, the associated environmental problems and possible solutions? The quiz "Plastics in the environment - What do you know?" invites you to test your knowledge around the topic of plastics in five categories. Furthermore, the category "Questions for adults & children" contains questions suited for children.

The policy brief discusses the different policy pathways to reach the climate target, as presented in the EU Commissions Impact Assessement of the 2030 target plan. There are different ways how the EU can reduce emissions to -55%: mainly through tighter regulation and standards, primarily via carbon price or trough a mix of both. The policy mix route may seem most attractive: politically, it is the path of least resistance, as it continues on the current trajectory. And it promises the best of both worlds – the efficiency of carbon pricing and the certainty of regulatory approaches. At the same time, the mix has some conceptual arguments in favor: companion policies, like standards and infrastructure investment, ensure that consumers have more climate-friendly options to choose from and bring down their cost. Thereby, they make it easier to stomach higher carbon prices.

Doris Knoblauch gave a presentation on plastic waste at the Freudberg School in Berlin on 9 December 2020. The lecture took place as part of the "Plastic Pirates" project.

In the wake of Joe Biden's election as 46th President of the United States, Dr. Camilla Bausch contributed a blog post for the Global Public Policy Institute's Peace Lab on how multilateralism could help address the climate crisis. This is a timely contribution as it is complimentary to the current work on the German government's new White Paper on multilateralism. In her blog post, Dr. Bausch addresses a broad range of climate diplomacy topics, taking into account the role of Germany as well as the European Green Deal, the Paris Climate Agreement, the UN Agenda 2030, the dynamics within the G20 and the role of science.

This article by Doris Knoblauch and Hannes Schritt (both Ecologic Institute) is part of the anthology "Einfach weglassen? Ein wissenschaftliches Lesebuch zur Reduktion von Plastikverpackungen im Lebensmittelhandel" (Simply Omit? A Scientific Reader on the Reduction of Plastic Packaging in the Food Trade). It deals with the emergence of plastic packaging in Germany and its known environmental impacts. The authors demonstrate that there is a close correlation between the amount of plastic packaging produced and the gross domestic product (GDP) - which, interestingly, is stronger than the correlation between GDP and packaging overall. In this context, avoidance strategies and improvement options for the circular economy are discussed.
