In this publication, we present the results of an acceptance study in two case study regions in Germany. We investigated farmers' and other soil experts' perceptions of subsoil amelioration as an approach to adapt to climate change. In addition, we analyzed the factors that influence their willingness to adopt specific measures to improve the subsoil. Applying q-method and focus groups, we surveyed overall 86 actors in the agricultural sector. The article is published in Frontiers in Agronomy, Volume 3, April 2021 and is available for download.

Published in April 2021, this policy brief identifies four options for increased multilateral cooperation that support an international shift towards sustainable food systems and help to increase the global 2030 climate ambition at the same time. The identified initiatives focus on activities that reduce food loss and waste and support plant based diets, following a 'food systems approach.'

Decoupling economic growth and resource use is a core objective of the "European Green Deal". How this is to be achieved is formulated in the new "Action Plan for the Circular Economy" and the "Industrial Strategy" of 2020. Reason enough to take a closer look at the current but also the older strategy papers – which concrete goals do the strategy papers contain – and which ones not? Which areas are addressed and which measures proposed – and what is announced for the near future? Is today's resource conservation policy more ambitious than in its early days? This paper presents the key political documents of European resource policy and traces lines of development.

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.

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.

Published by the Pontifical Academy of Sciences a new book deals with the reduction of food loss and waste globally. It includes an article that sums up results of the EU research project REFRESH, and in particular the work on policies to reduce consumer food waste, lead by the Ecologic Institute. The book is available for download.

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.

The discussion about plastic waste is anything but new for German municipalities. In fact, as early as the 1980s, numerous German municipalities were experimenting with plastic waste prevention regulations and waste prevention in general. A further impetus for plastic waste prevention was provided in the early 1990s with the discussions on the introduction of a nationwide packaging ordinance. After almost three decades of stagnation – including setbacks with regard to the expansion of return systems and the increase of single-use packaging – the issue of plastic prevention and packaging reduction in municipalities is now receiving renewed attention as a result of increased societal awareness and political regulations at EU level.

Bioeconomy currently enjoys a high political priority; at the same time, the concept, which last received a boost in 2018 in the form of the updated EU Bioeconomy Strategy, is not without controversy and contains many conflicting goals. This is where the article by Zoritza Kiresiewa (Ecologic Institute), Franziska Wolff and Martin Möller (both Öko-Institut e.V.) comes in. The authors argue that bioeconomy can only contribute to the achievement of sustainability goals if the political framework is appropriate. Whether or not strategies will have an impact depends on each individual case. Bioeconomy pathways should be designed and tested accordingly.

SDG 12 'Ensuring sustainable consumption and production patterns' aims at the necessary changes in our lifestyles and ways of doing business. Together with Adelphi and Wuppertal Institute Ecologic Institute set-up a database of activities in Germany, which contribute to implementing SDG12 in Germany. The database currently comprises more than 120 activities, including civil society and business initiatives as well as policy programs and actions.

On 17 September 2020, the European Commission proposed to raise the EU climate target for 2030, so as to reduce greenhouse gas emissions by 55% compared to 1990. In this policy brief, CLIMACT and Ecologic Institute unpack the Commission's impact assessment for the new target. The brief analyses key policy options and analytical results and compares them to recent studies, in particular CLIMACT's 2030 modelling results. Within the framework of the tightened target, the EU Commission proposes to extend the EU Emissions Trading Scheme to buildings and road transport – a major change to the EU's current climate policy architecture. The team discusses potential implications and provides context to the sectoral developments and policies. The briefing highlights key points where the Commission diverges from other studies, identifying climate mitigation potentials that merit more attention in future analysis.

Sustainable use of natural resources in the long term requires not only the application and dissemination of resource-saving technologies and infrastructures, but also changes in individual and collective behaviour and social practices. Against this background, different methods were combined in the project "Trendradar Resource Policy" to identify and evaluate societal trends and resource policy measures. Using trend analysis, 20 socially relevant trends were identified and qualitatively described. These trends were then empirically reflected by eliciting perceptions, attitudes and interpretation patterns of the general population in a three-week Moderated Research Online Community (MROC). At the same time, policy measures were identified and qualitatively assessed in terms of relevance and possible barriers to implementation.
