This infographic summarizes the data on the monitoring studies, differentiated by screen bar spacing and build-out flow rate at the sites entered in the Atlas Fish Protection & Downstream Fish up to a build-out flow rate of 200 m³/s. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

This infographic evaluates the information on the type of fish protection systems at the sites listed in the Atlas of Fish Protection & Downstream Fish. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

This infographic shows the dimensions of the screen field, entered in the Atlas of Fish Protection & Downstream Fish, for 37 sites. The resulting screen widths are between 2.35 m and 51.9 m and the screen heights are between 0.8 m and 12.20 m. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

For 65 sites, the rake bar spacing is given in the atlas. This is registered in five classes. This infographic visualizes the information. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

This infographic evaluates the information on the aspects of the monitoring studies (multiple answers possible) at the sites entered in the Atlas of Fish Protection & Downstream Fishways. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

The illustration provides an overview of the information structure of the Atlas sites. It is part of a fact sheet on fish protection and downstream fish migration measures.

The German government has set itself major goals for the expansion of solar energy. One important force in this is citizen energy. Does the draft amendment to the Renewable Energy Sources Act (EEG) meet the high expectations for an acceleration in tenant electricity, community self-consumption and renewable energy communities?

The World Water Day, was introduced by the United Nations in 1992 to remind people of water as an essential resource for life. For this year's theme "Groundwater – making the invisible visible", Ecologic Institute co-organized a webinar to present an augmented reality app that was developed as part of the project Digital Water City (DWC). The webinar was moderated by Alexander Sperlich (BWB) and Dr. Ulf Stein (Ecologic Institute).

This paper is a slight adaptation of the German-language analysis "Wasserstoffimportsicherheit für Deutschland – Zeitliche Entwicklung, Risiken und Strategien auf dem Weg zur Klimaneutralität", published in December 2021. The analysis takes a close look at Germany’s future need for hydrogen imports, hydrogen import-related risks as well as strategies to secure hydrogen imports.

The German government has put the formation of an 'ambitious, bold, and cooperative' climate club on top of its G7 Presidency agenda. But what is a climate club? And what type of climate club should the German G7 Presidency push toward? This policy brief provides some answers to these questions and formulates recommendations for the German Presidency.

This fact sheet introduces the "Atlas Fischschutz & Fischabstieg" and its contents. The fact sheet "Fischschutz- und Fischabstiegsmaßnahmen – Praxisbeispiele im Überblick (Fish protection and downstream fish migration measures – Practical examples at a glance)" is available for download.

This compendium, published by Ecologic Institute, aims to sharpen relevant terms and thereby aims to contribute to the heterogeneity of the scientific community on "plastics in the environment". In addition, the brochure is intended to help ensure that communication with and by non-scientific actors on the topic is based on a terminologically correct foundation, especially in emotionally charged debates. After all, these debates are often highly relevant in shaping our future, and it seems important that the necessary political, social and economic decisions should be taken based on knowledge and factual information. The compendium is available for download.

Whether or not microplastics have harmful effects on plants and animals has not yet been conclusively established. The different properties of microplastics determine whether and how the microplastics are absorbed by living organisms and whether they are harmful to them. Compared to other pollutants in the environment (e.g. pesticides), microplastics do not have a uniform effect on living organisms. In addition, the effects of microplastics often cannot be distinguished from the harmful effects of other particles and substances found in the environment.

The question of the limits to growth is more relevant than ever. Historically, economic growth has almost always been accompanied by increasing environmental damage. The policies of European countries now want to break this historical link through "green growth". The economy should continue to grow, but without negative consequences for the environment. From a scientific perspective, however, it is disputed whether such a decoupling is realistic. Dr. Michael Jakob from Ecologic Institute discussed this apparent contradiction between politics and science with Prof. Dr. Doris Fuchs and Dr. Steffen Lange during a press briefing on 25 February 2022.

The article reflects on the 59th Tutzing Symposion entitled "Polymers for a better life and circular economy" that took place as an online event in October 2021. Based on the presentations at the symposium, the contribution provides an overview of current debates on the circular plastics economy, as well as insights into existing political regulations, present challenges, and possible future developments with regard to this major societal project.
