Profound societal transformations are needed to move society from unsustainability to greater sustainability under continually changing social and environmental conditions. A key challenge is to understand the influences on and the dynamics of collective behavior change toward sustainability. In this paper, the authors of whom Grit Martinez of Ecologic Institute is one, demonstrate how affective narrative expressions influence transitions to more sustainable collective behaviors.

Democracies need a compass, writes Nils Meyer-Ohlendorf in the ipg-journal. To find their way in the haze of polarised debate, the compass must offer four things. First, it must help to understand pluralism – it must help to endure and respect different opinions. Conversely, it must recognise that some positions are outside the democratic spectrum. Thirdly, it must ensure precise language. And fourth, it must identify trends in democracies. The article is available online.

The new President of the European Commission, Ursula von der Leyen, has promised a European climate law. What it should look like describe Nils Meyer-Ohlendorf and Katharina Umpfenbach in the Tagesspiegel. The law should close five gaps.

In this article, Dr. Grit Martinez ist concerned with the role of culture and history in relation to local knowledge and values, as these are displayed in the interpretations and actions of distinct groups regarding climate change. She argues that it makes sense to communicate the climate in a manner appropriate to the given cultural-historical context and imaginary and to the relevant semiotic and material views of the people in it.

The circumstances under which different ecosystem service benefits can be realized differ. The benefits tend to be coproduced and to be enabled by multiple interacting social, ecological, and technological factors, which is particularly evident in cities. As many cities are undergoing rapid change, these factors need to be better understood and accounted for, especially for those most in need of benefits. We propose a framework of three systemic filters that affect the flow of ecosystem service benefits: the interactions among green, blue, and built infrastructures; the regulatory power and governance of institutions; and people's individual and shared perceptions and values. We argue that more fully connecting green and blue infrastructure to its urban systems context and highlighting dynamic interactions among the three filters are key to understanding how and why ecosystem services have variable distribution, continuing inequities in who benefits, and the long-term resilience of the flows of benefits.

The Baltic Sea Action Plan and the EU Water Framework Directive both require substantial additional reductions of nutrient loads (N and P) to the marine environment. Focusing on nitrogen, we present a widely applicable concept for spatially differentiated regulation, exploiting the large spatial variations in the natural removal of nitrate in groundwater and surface water. By targeting mitigation measures towards areas where nature’s own capacity for removal is low, spatially differentiated regulation can be more cost-effective than the traditional uniform regulation. We present a methodology for upscaling local modelling results on targeted measures at field scale to Baltic Sea drainage basin scale. The paper assesses the potential gain and discusses key challenges related to implementation of spatially differentiated regulation, including the need for more scientific knowledge, handling of uncertainties, practical constraints related to agricultural practice and introduction of co-governance regimes.

Societal transformations are often initiated by individuals. This also applies to the sustainable economy issue: There are particularly committed people behind many smaller and larger developments that have been set in motion in recent years. Some of these "change agents" who were involved in projects of the "Scientific coordination of research projects on a sustainable economy" (NaWiKo) have been presented as part of the project's dissemination work.

The capacity of multifunctional natural areas to simultaneously address user preferences, answer municipal needs, and fulfil wider political obligations is far from being fully realised. The present article responds to this situation and highlights the Q-method as an effective approach for assessing and integrating user viewpoints on urban GBI and its benefits in urban decision-making and planning processes.

Maintaining a strong EU and implementing effective climate policies go hand in hand with one another. Indeed, they are pretty much the best of friends. A stable, prosperous and climate-resilient Europe requires effective climate action; and effective climate action needs a strong EU. When addressed from this angle, there is a lot of agreement among EU policymakers, who often speak about the importance of climate action when addressing the future of the EU. However, there is more to it than general agreement. Climate policies and the future of the EU can reinforce each other in concrete ways.

On 9 May 2019, the European Council meets in Sibiu (Romania). Not long ago, this meeting was expected to be an important milestone in the Process on the Future of the EU. Now, expectations are much lower. Avoiding controversy is the first order of business. But the core questions of the Process on the Future of the EU will not go away: how to maintain and develop a strong EU? This question will stick with us, and it will keep the new Parliament and the new Commission busy.

The Energiewende means a transition from the old, nuclear-and-coal based, to a sustainable and digitalized energy system. This is a complex endeavor: the number of actors involved increases and their functions overlap. While digital technologies bring automation and potential for relief, they are an ambivalent phenomenon: with no comprehensive laws on data protection, it is unclear what is going to happen to the tremendous amount of data collected by digital appliances. Besides, technologies like blockchain are often so energy-intensive that they eat up the amount of resources that they are trying to save. Therefore, political design must actively shape a digital and ecologically sustainable energy transition – it will not happen by itself.

Energy security – the uninterrupted supply of energy at reasonable prices, as defined by IEA – has both external and internal dynamics. It can be ensured through local adequacy, that is, abundant and varied forms of indigenous energy resources, but the countries that face local shortages, as in Bangladesh, depend on imports. Shafiqul Alam explains in his online article in the Dhaka Tribune how internal measures could attenuate reliance on external sources.

The use of the term "driving ban" can give the impression of a general and comprehensive ban on driving. In this sense, it means, rather, a ban on mobility. The term thus does not only suggest a banishment, but also an interference in the personal freedom of all drivers, not only of diesel drivers. "Traffic restrictions" is the more precise term with respect to the content. Dr. Nils Meyer-Ohlendorf, Head of International and European Governance, and Katharina Umpfenbach, Coordinator Energy of the Ecologic Institute, discuss this in the Süddeutsche Zeitung. The article is available online.

As part of the EU H2020 RURECO project, Dr. Josselin Rouillard carried out a one-month research exchange with the University of Davis, California focusing on sustainable groundwater management in Europe, France and California. Seminars with academic staff at UC Davis and Stanford University were organised comparing European and Californian strategies for sustainable groundwater management. Workshops and meetings were organised with the State Water Resource Control Board and nine groundwater sustainable agencies across the state of California. The blogpost is linked in the article.
