This report documents the project work and results of the R&D project "Information Platform for the restoration of rivers", which was jointly carried out by Ecologic Institute, Planungsbüro Zumbroich and the Institute of Aquatic Ecology and Fish Biology, Jena (IGF Jena) from 2017 to 2020. The aim of the project was to create an online information platform about river restoration (Part I of the project report) and the analysis of German restoration projects in regard to their monitoring (Part II of the project report). The report is available for download.

What innovations are needed to develop a climate-neutral energy system of the future? How can the national and European climate targets be achieved in 2030? What can Germany do to advance the European Green Deal together with the other member states? These and other questions will be the focus of the virtual Copernicus Symposium on 9 and 10 June 2021.

The recent decisions by the Constitutional Court and the German government on national climate legislation have brought new wind to the climate debate. But what does this mean for Berlin? Are the new targets suitable for transfer to the capital? Is the level of ambition sufficient to limit CO2 emissions "in line with Paris requirements" and allow Berlin to shoulder its fair share of the 1.5 degree target? And which areas of improvement do Berlin's politicians have to tackle now in order to set the course towards a climate-neutral Berlin 2045 without burdening the city's most disadvantaged residents in particular?

Various economical methods are available for the monetary assessment of the effects of environmentally induced diseases as well as the resulting deaths. This report serves as a basis for the development of concrete monetary valuations of environmental burdens of disease, which is illustrated by three case studies.

The Heinrich Böll Foundation, the book designer Gesine Grotrian and the Ecologic Institute as expert support have worked closely with young people to develop a book for people aged 12 and over that describes the history, production and risks of our plastic consumption in a straightforward, colourful and clearly understandable way. It also shows alternatives and ways out of dealing with plastic and its dangers. The book is available online.

This status report was prepared within the framework of the cross-cutting issue 1 "Analytics and reference materials" of the research focus Plastics in the Environment. It summarizes the contents of the project discussions and coordination within the cross-cutting issue. The organization of this ongoing process of development or elaboration has been supported by several events between 2018 and 2020.

Plastic waste, plastic parts and microplastics can be found everywhere in the environment. Plastic particles are also detected in living organisms. But what exactly is the situation? To find out, the German Ministry of Research is funding the research priority "Plastics in the Environment" with around 40 million euros. Some of the results of the 20 funded research projects are presented in this video. Further results of the research projects as well as information on the activities of the research focus are available on the website.

For Germany to reach its climate targets, new ways of thinking mobility are essential. For the federal state of Lower Saxony, the mobility transition is particular challenging due the important role cars play in the region. The report "Ways to Sustainable Mobility" (WenaMoNi) analyses in detail where Lower Saxony stands and proposes next steps. Ecologic Institute analysed the legal framework and identified key actors promoting electric and hydrogen-based mobility. Katharina Umpfenbach and Ricarda Faber compared the existing policy instruments to best practices in other countries and to recommendations from science. The analysis shows that a policy approach built on subsidies which has been favoured so far, must be supplemented by pricing instruments if climate targets are to be reached.

This study by Ecologic Institute analyses the potential of areas of law beyond the water law to achieve the objectives of the Water Framework Directive. Germany has so far failed to achieve the various objectives of the Water Framework Directive. According to the thesis on which the study is based, reason for this is not only the lack of financial, personnel and organisational prerequisites, but also the lack of integration of water protection concerns into other areas of law beyond water law. The study is available for download.

Germany's Polar research activities contribute to numerous initiatives and include links to climate and biodiversity protection. To prepare for future challenges and address the most pressing issues, the federal government launched a process to develop a new polar research agenda. On 19 May 2021, the steering group of the process including Ecologic Institute's Arne Riedel, handed over the concept paper on the "Changing Polar Regions" developed by over 100 experts to the Federal Ministry for Education and Research.

In a decision published in May 2021, the German Constitutional Court held that the Federal Climate Change Act is partly unconstitutional and has to be amended by the end of 2022. This policy brief explains the court's key arguments and findings.

The Conference on the Future of Europe begins on 9 May 2021. This political process can become a milestone in EU climate policy making – provided that its recommendations are specific and focus on the EU's ability to act, writes Nils Meyer-Ohlendorf in the Tagesspiegel. He makes three proposals how the conference can support EU climate policies.

The 6th expert dialogue on sustainable timber construction took place on 6 May 2021. Speakers included architects and engineers as well as experts from relevant research projects who presented and discussed practical topics related to timber construction in the capital region.

The "Plastic Pirates" are a citizen science project for young people to research litter pollution in German rivers. The article describes the background and objectives of the project, explains the scientific methodology and presents some of the results from the first years of the project.

On 30 April 2021 at the online Berliner ENERGIETAGE, the research network Ecornet Berlin presented how tenants can benefit from the energy transition.
