The project examined the effects, processes and support options for implementing innovative infrastructure coupling.The present volume analyses the effects of innovative couplings on performance, resilience, resource efficiency, and social and economic compatibility. A "sustainability check" with 26 criteria was developed and tested in an expert survey. Coupling infrastructures does not automatically lead to greater sustainability, but coupled infrastructure systems have the potential to contribute to resource conservation and security of supply. This requires a differentiated consideration of the effects on sustainability.

This research report contains the results of the UBA-project "Environmental guidelines of a German Arctic policy". It highlights several starting points for the German environmental department to foster environmental protection in the Arctic, even from a non-Arctic state’s point of view. The report also describes the activities undertaken within the project to raise awareness with the general public on existing links between Germany and the Arctic. Those activities include inter alia an explanatory video and a public event.

On 19 May 2020, Doris Knoblauch moderated a media training for the research focus "Plastics in the Environment". The journalist Ralf Nestler provided the content input. In addition to his work at the Tagesspiegel, he also worked as a scientist at the GFZ German Research Centre for Geosciences in Potsdam. Nestler thus knows both sides of the relationship between science and journalism.

With more than 1500 participants in the live stream and via YouTube, the online webinar "Saving the climate with knife and fork? How our eating habits affect the environment" on 18 May 2020 was a complete success. Together, Tanja Dräger de Teran (WWF) and Stephanie Wunder (Ecologic Institute), highlighted the links between daily nutritional routines and their impact on climate, land use and health.

The current global pandemic presents both risks and opportunities for the transition to a more sustainable future in Europe. At the launch event for the newest report of the German Advisory Council on the Environment (SRU), Dr. Camilla Bausch discussed the importance of the European Green Deal at this moment of crisis with Prof. Dr. Christian Calliess.

What do environmentally friendly economic stimulus programs look like? In the Tagesspiegel, Nils Meyer-Ohlendorf takes stock of the stimulus packages adopted during the 2009 financial crisis. Stimulus packages should clearly exclude measures that harm the environment.

This study analysed the effects of the agricultural water protection measures implemented in the collaborative approach, e.g. with regard to their potential for reducing nitrogen leaching into groundwater and regarding the level of acceptance among farmers. The study area consisted of 18 drinking water cooperations covering 20 drinking water protection zones.

The vade mecum on complaint-handling and citizen engagement delivers one of the nine actions in the European Commission's 2018 environmental compliance assurance action plan. It was prepared between May 2018 and May 2019 by Directorate-General Environment of the European Commission together with the Ecologic Institute and individual experts nominated by members of the Environmental Compliance and Governance Forum.

This article introduces the German Federal Environment Agency's online information platform on river restoration. It was designed, compiled and implemented between 2017 and 2020 by Ecologic Institute, Planungsbüro Zumbroich and IGF Jena. The information platform provides basic knowledge on the restoration of rivers and serves to gain acceptance for restoration measures. It addresses towns and municipalities, water management authorities, water bodies associations, fishing associations and citizens' groups.

To combat the Corona Crisis, states are pushing their limits. Nils Meyer-Ohlendorf argues in the Tagesspiegel that this should not happen in climate policy. There is no "what-ever-it-takes-response" to stop the advanced climate crisis but only swift and continuous action now.

While circular processes offer potential for small and large companies, such processes are not (yet) established across the board. For circular processes to be applied widespread, exchange between science and companies must be improved. As part of an national research project funding scheme on the sustainable economy, three workshops were dedicated to businesses and science actors to exchange information on sustainability innovations along value chains. This German paper summarises experiences made and lessons learned from these workshops.

On 4 March 2020 the European Commission published its proposal for a European climate law. The present Commission proposal raises a number of questions, such as what steering effect can the long-term orientation really achieve or will the climate law effectively close existing gaps in the processes of EU climate policy? Together with experts, we have further explored these questions.

The EU is to be climate-neutral by 2050. In March 2020, the European Commission presented its draft law, which for the first time legally anchors the goal of climate neutrality. This is a milestone in climate protection policy. Ursula von der Leyen even compared this goal with the moon landing.

The final event of the dialogue forum "Wirtschaft macht Klimaschutz" took place on 11 March 2020 in Berlin. Over the past two years, representatives from more than 100 companies have jointly developed ideas, projects and concrete steps to promote climate protection in their companies. Organised in five thematic working groups, the Dialogue Forum has brought together climate protection pioneers among German companies and facilitated exchange of ideas across sector boundaries.

The EU Commission's proposal for an EU climate law marks important progress. It sets an unmistakable target for climate neutrality in the EU by 2050, writes Nils Meyer-Ohlendorf in the Tagesspiegel. Nevertheless, the proposal has five gaps that should be closed during the legislative process.
