The project examined the effects, processes and support options for implementing innovative infrastructure coupling. Current developments, the associated transformation processes including supporting and hindering factors as well as potential sustainability effects of coupled infrastructure solutions were examined. The focus is on innovative, i.e. not established, couplings (understood as niche innovations) in the transport, energy, water, wastewater, waste management and information and communication technologies (ICT) sectors. The present volume provides a summary of the results, which are available in three sub-reports.

The project examined the effects, processes and support options for implementing innovative infrastructure coupling. The present volume examines local innovation processes in four case studies. Especially when it comes to innovations, there are no standard solutions. The technical systems must be embedded in supportive organisational structures, be economically feasible and implementable, function in a social context and encounter a enabling political and legal framework. Local actors, especially public utilities, are able to take the new, often uncertain paths, if the right framework conditions are in place.

The project examined the effects, processes and support options for implementing innovative infrastructure coupling. The present volume examines development paths, success factors and barriers as well as the contribution of infrastructure couplings to sustainability transformation and design options. Implementation processes are often complex, breaking new ground and requiring the cooperation of actors in completely new constellations and responsibilities. Whether sustainability transformation is successful on the local level depends on numerous factors that can also be shaped on local level in a systematic way. Innovations promote new structures, networks, new behaviour and knowledge.

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.
