The discussion about voluntary vs. mandatory offsets has risen to particular attention with the planned No Net Loss initiative of the EU and the envisaged introduction of a mandatory compensation scheme at EU level. However, biodiversity offsets are far more complex than this distinction of two types of biodiversity offsets implies. Consequently, the aim of this study was to develop a refined typology with regard to the voluntariness of biodiversity offsets. To this end, four consecutive steps have been applied: 1. Deduction of an impressionistic classification of types, 2. Derivation (and reduction) of relevant attributes/criteria for voluntariness from the theory, 3. Substruction of the underlying attribute space and combinations of attributes and 4. Transformation (rectification) of the impressionistic types and analysis of meaningful correlations. As a result, a typology with seven types has been built: 1. Regulatory offsets: required by law and enforced 2. Conditional offsets: required by financial institutions (e.g. International Finance Corporation) 3. Enabled offsets: fostered by governments and NGOs through pilot schemes, guidance etc. 4. Sectoral offsets: take part in a voluntary self-commitment of a sector (e.g. mining) 5. Corporate offsets: resulting from a voluntary self-commitment of a corporation 6. Local offsets: single offsets, that are most likely developed at local level in a consensual process 7. Altruistic offsets: truly voluntary offsets that are driven by the altruistic motivation to make a positive impact The state of the scientific knowledge and the practical evidence explored throughout this study encourage the analysis (and use of) of the various forms of voluntary biodiversity offsets, in particular with regard to the evaluation of their outcome in terms of effectiveness and efficiency. This can help to contribute to an informed debate about biodiversity offsets and how they can be delivered in practice. ; peerReviewed

National audience ; Mitigation banking in Germany (Ökokonto) has developed since the 1990s. In order to compare the French and German mitigation banking systems, we carry out an analysis of strengths, weaknesses, opportunities and threats to highlight the characteristics of compensation by Ökokonto. The main ecological, territorial and organisational implications are highlighted in order to draw first lessons for the French practice of mitigation banking. ; La compensation mutualisée en Allemagne (Ökokonto) s'est développée dès les années 1990. Dans la perspective d'une mise en regard des systèmes de compensation mutualisée français et allemand, nous proposons une analyse « Atouts, Faiblesses, Opportunités et Menaces » pour souligner les caractéristiques de la compensation par Ökokonto. Les principales implications écologiques, territoriales mais aussi organisationnelles sont mises en avant pour ensuite en tirer de premiers enseignements vis-à-vis de la pratique française de la compensation mutualisée.

The European Union (EU) is committed to tackling the issue of climate change, which poses serious risks to the global environment and human well-being. Supporting renewable energy is a key policy direction for the EU to lower its contributions to climate change. However, renewable energy technologies have diverse effects on the environment and on society. These effects can be considered a complex system of interacting elements and are challenging to assess. Conceptual models are a way of synthesizing this information to obtain an overview of the system and essential insights. We present the results of an activity to assess the impacts of EU renewable energy policies on overseas biodiversity and the United Nations (UN) Sustainable Development Goals (SDGs). This was carried out as part of the EKLIPSE (EKLIPSE (Establishing a European Knowledge and Learning Mechanism to Improve the Policy-Science-Society Interface on Biodiversity and Ecosystem Services) mechanism to synthesise environmental knowledge in response to specific requests by decision-makers at the European level. We carried out a participatory process to collate expert knowledge into a conceptual model using a Fuzzy Cognitive Mapping Approach (Özesmi and Özesmi 2004), with the Mental Modeler software for mapping (Gray et al. 2013). The participants were guided to connect significant EU policies associated with renewable energy, the technologies they support, and known impacts of these technologies on biodiversity and the SDGs, drawing on a preliminary review of the literature. The individual models obtained were integrated into a single model (see Suppl. material 1 for images). This was then subject to network analysis, which reveals the collective effects of different renewable energy technologies (RETs) on the wider socioecological system. Our findings highlight that RETs have complex and at times disparate effects on biodiversity and the SDGs, acting through a variety of mediating processes. They benefit the SDGs on balance, particularly climate-related SDGs. Mitigation of biodiversity impacts remains a concern, and processes such as habitat change were found to be influential here. Our results suggest that policymakers must focus on implementing appropriate environmental impact assessments, guided by these mediating processes. This would minimize any negative environmental impacts of RETs, while maximizing the benefits.

The aim of EKLIPSE is to develop a mechanism to inform European-scale policy on biodiversity and related environmental challenges. This paper considers two fundamental aspects of the decision-support mechanism being developed by EKLIPSE: 1) the engagement of relevant actors from science, policy and society to jointly identify evidence for decision making; and 2) the networking of scientists and other holders of knowledge on biodiversity and other relevant evidence. The mechanism being developed has the potential not only to build communities of knowledge holders but to build informal networks among those with similar interests in evidence, be they those that seek to use evidence or those who are building evidence, or both. EKLIPSE has been successful in linking these people and in contributing to building informal networks of requesters of evidence, and experts of evidence and its synthesis. We have yet to see, however, significant engagement of formal networks of knowledge holders. Future success, however, relies on the continued involvement with and engagement of networks, a high degree of transparency within the processes and a high flexibility of structures to adapt to different requirements that arise with the broad range of requests to and activities of EKLIPSE.

In March 2019, German-speaking scientists and scholars calling themselves Scientists for Future, published a statement in support of the youth protesters in Germany, Austria, and Switzerland (Fridays for Future, Klimastreik/Climate Strike), verifying the scientific evidence that the youth protestors refer to. In this article, they provide the full text of the statement, including the list of supporting facts (in both English and German) as well as an analysis of the results and impacts of the statement. Furthermore, they reflect on the challenges for scientists and scholars who feel a dual responsibility: on the one hand, to remain independent and politically neutral, and, on the other hand, to inform and warn societies of the dangers that lie ahead. ; ISSN:0940-5550

National and local governments need to step up efforts to effectively implement the post-2020 global biodiversity framework of the Convention on Biological Diversity to halt and reverse worsening biodiversity trends. Drawing on recent advances in interdisciplinary biodiversity science, we propose a framework for improved implementation by national and subnational governments. First, the identification of actions and the promotion of ownership across stakeholders need to recognize the multiple values of biodiversity and account for remote responsibility. Second, cross-sectorial implementation and mainstreaming should adopt scalable and multifunctional ecosystem restoration approaches and target positive futures for nature and people. Third, assessment of progress and adaptive management can be informed by novel biodiversity monitoring and modeling approaches handling the multidimensionality of biodiversity change.
