Carbon pricing is a policy instrument that is very popular with researchers and many policy makers as well. To be implemented effectively, it requires widespread acceptance by society. This paper presents an empirical study carried out in Germany directly before the implementation of its new carbon-pricing scheme for fuels in 2021.

This article reviews the role of ponds and pondscapes in delivering Nature's Contributions to People and provide an overview of the challenges and opportunities for their broader implementation as Nature-based Solutions. The authors, among them Manuel Lago (Ecologic Institute) propose a conceptual framework that can help the implementation of pond Nature-based Solutions, and that outlines future research needs.

The European Commission has proposed a Carbon Border Adjustment Mechanism (CBAM) to enable ambitious climate policies in EU member states and to incentivize emission reductions in other countries. This paper adopts a dynamic, multilevel, polycentric perspective to discuss how domestic as well as foreign interest groups would be affected by the policy.

The Commission's proposal to certify carbon removals is a climate policy milestone, but it steers EU climate policy towards dangerous shoals. Nils Meyer-Ohlendorf – together with Anne Siemons and Hannes Böttcher from Öko-Institut – discusses how to circumnavigate them in the Tagesspiegel.

This article written by Dr. Ulf Stein and Benedict Bueb from Ecologic Institute together with researchers of the French National Institute of Agricultural Research (INRAE) presents insights of two case studies, in Paris and Berlin, which investigated the potential of two mobile applications to make urban water management visible to the public and thus increase awareness about certain water management aspects.

The COP27 in Sharm El-Sheikh was intended by the Egyptian presidency to be an implementation summit. The key outcome agreed was a financing mechanism with a fund specifically for damage and loss. Apart from that, the substantive outcomes of COP27 were mostly disappointing. This article by Dr. Ralph Bodle, Arne Riedel and Dr. Camilla Bausch provides an overview of selected outcomes, as well as insights into the process and the assessment by German civil society.

To tackle the "plastic crisis", the concept of circular economy has attracted considerable attention over the past years, both by practitioners and scholars alike. Against this background, Linda Mederake, Ecologic Institute, reflects in this opinion paper from a political scientist's point of view on key issues currently under discussion regarding the implementation of a circular plastics economy.

This article written by several researchers from Ecologic Institute provides a review of different digital tools and resources available to support related decision-making processes in the search for solutions for Integrated Water Resources Management (IWRM). Furthermore, it introduces the Diagnostic Water Governance Tool (DWGT) that builds on a clear diagnosis-therapy-logic.

The European Commission has proposed a carbon border adjustment mechanism (CBAM) that would apply the carbon price prevailing in the EU emissions trading system to import-related emissions. In July 2021, the authors, including Dr. Michael Jakob of Ecologic Institute, conducted a survey to study perceptions of an EU CBAM among German key stakeholders from industry, civil society, and research. They find that substantial support for CBAM exists, as well as the expectation that the mechanism will eventually be introduced. Divergent views on key design options were found among stakeholder groups.

Strict regulation does not have to stifle the emerging market for green hydrogen — just the opposite, write Benjamin Görlach and Dr. Michael Jakob of Ecologic Institute. They argue that a unified system for monitoring, certifying and tracking green hydrogen production and trade is key to all this. The op-ed can be accessed at the EURACTIV website.

The term "populism" is ubiquitous in political debate nowadays. But not only is the term meaningless - it poses a real problem for democracy and the political debate, writes Dr. Nils Meyer-Ohlendorf in the IPG. The article is available online.

The EU Effort Sharing Regulation is of great importance for EU climate policy, but its revision hardly gets public attention. This is a problem. Without a public debate, important structural issues of EU climate policy could be set wrong. In the Tagesspiegel Nils Meyer-Ohlendorf makes proposals for a good outcome of the trialogue negotiations.

In her plans for 2023 addressed to the EU Parliament, President of the EU Commission von der Leyen did not mention the proposal for a Sustainable Food System legislative framework (SFSF). This created speculation about the timeframe of this key proposal, which has been put forward as a cornerstone of the EU Green Deal for the agri-food sector. This blogpost, co-signed by members of the Think Sustainable Europe network, underlines the importance of the SFSF to be proposed next year in order to drive a sustainable transition of the EU food system, given the urgency of such a transition.

The Commission's proposal on the certification of Carbon Dioxide Removals (CDR) could be a milestone of EU climate policy making. It can put the EU on the right track – with a watertight CDR definition, and a firewall between removals and reductions; or the wrong track – dubious low-impact carbon removal schemes that pretend to offset what cannot be offset. As the integrity of EU climate policy is at stake, the EU cannot afford to take the wrong turn, writes Nils Meyer-Ohlendorf in the EU Observer.

Is infinite economic growth possible in a world with finite natural resources? For many environmentalists the answer to this question is a clear no. But economists, such as Dr. Michael Jakob of Ecologic Institute, often disagree, emphasising that economic growth can occur as productivity increases, even as consumption of natural resources and greenhouse-gas (GHG) emissions decrease. His guest op-ed is available online.
