Climate change, biodiversity loss and ecosystem degradation are linked and interdependent challenges needing to be addressed in an integrated manner. Synergies can be enhanced by building on the multifunctionality and multiple benefits of biodiversity and healthy ecosystems, captured under Nature-based Solutions (NbS). These topics were explored in the session "Nature as a solution: For resilience, mitigation and sustainable development" during the 5th European Climate Change Adaptation Conference (ECCA2021). Ecologic Institute's McKenna Davis was a keynote speaker, presenting on the EU and global environmental policy landscapes and their role as a help or hindrance to NbS uptake.

The 2021 annual conference of German Association of Dietitians has put a focus on sustainability and its relevance for the work for dietitians as well as policy makers. Stephanie Wunder gave a impulse presentation on this topic entitled "Effectively using synergies between health-promoting and environmentally friendly nutrition".

What are the key ingredients of a "Sustainable Recovery for a Green Future?" This was the topic of two events organized by Think20 (T20) during the Italian G20 presidency. Dr. Camilla Bausch, co-chair of the T20 Task Force on environmental issues, spoke on carbon neutrality, long-term climate strategies and the European Green Deal.

The objective of transformative research is to find out, together with actors from the corporate sector, politics and civil society, how our economic and social system can be made more sustainable, and to jointly test possible solutions. Transformative research is thus also transdisciplinary - it involves actors beyond academia as equal partners. This kind of research involves certain methodological challenges and questions; some of these were discussed at the tF Symposium 2021: From Experiment to Mainstream. Martin Hirschnitz-Garbers and Christiane Gerstetter, both Senior Fellows at the Ecologic Institute, contributed to the online symposium, which was held in German language.

The Urban Agenda for the EU recognizes the importance of nature-based solutions as tools for sustainable recovery and development. Yet implementation and mainstreaming at city level remain limited. Can the European Green Deal support these efforts? What role can European research projects play? To answer these questions, McKenna Davis was invited as an expert to contribute to the European Urban Knowledge Network’s (EUKN) Policy Lab on 'The Urban Agenda for the EU, its 'green' actions and the European Green Deal'. The 18 March 2021 event aimed to unravel the 'green' actions of the Urban Agenda for the EU and develop concrete messages for the ministers under Slovenia's Presidency on how to support cities dealing with regulatory obstacles when trying to reach environmental goals.

To provide the G20 leaders with scientific advice, Think20 – a group of think tanks and academia from G20 countries – will work over the upcoming months on policy papers and recommendations.

How can think tanks serve as a catalyst for ideas and action? In view of a challenging year of dual public health and environmental crises, Dr. Camilla Bausch addressed this question at the Why Think Tanks Matter Forum. The forum brought together more than 700 think tank professionals from all around the world.

Invited by the Indian Centre for Science and Environment (CSE), McKenna Davis (Ecologic Institute) joined the "International Knowledge Conclave on Green Infrastructure" and presented on 'Policy instruments to promote urban nature-based solutions in Europe'. She focused on the range of policy, planning and financial instruments relevant for nature-based solution design, implementation and maintenance within a European context. Her presentation slides and a guidance document she co-authored are available for download.

Countries around the world are considering the introduction of national framework laws to make their climate policy more effective. A debate is underway in Israel on the adoption of such a climate law, to establish a clear institutional set-up and regular processes for climate action. Ecologic Institute's Matthias Duwe presented best practice lessons from European countries to policy-makers as inspiration for the law's design.

The Think2030 Conference got off to an inspiring start with keynotes by Dr. Camilla Bausch of Ecologic Institute, Prof. Hans Bruyninckx, President of the EEA and Prof. Klaus Töpfer, founder of TMG and former Executive Director of UNEP. Their speeches marked the opening of the 2-day conference on "Harnessing the European Green Deal to address the Climate Crisis". The conference marked the occasion of Ecologic Institute's 25th anniversary.

Training the next generation of environmental lawyers is crucial for ensuring that environmental law is complied with and can thus serve its function of protecting the environment. Christiane Gerstetter, Senior Fellow at the Ecologic Institute, co-moderated an online course for German and Russian students entitled "Ecolaw and ecoactivism in Germany and Russia".

With around 75% of EU population living in urban areas, cites will play a key role in curbing greenhouse gas emissions, reducing vulnerability to impacts of climate change and building resilience. Multifunctional nature-based solutions can be a powerful tool to jointly address climate change mitigation and adaptation in urban areas. A number of innovative pilot projects introduced in Berlin in the last 20 years were able to demonstrate in practice how cities can save energy, cool down buildings, reduce urban heat island effect and sequester and store carbon by working with natural climate solutions.

On October 12th and 13th the 2020 European Sustainable Development Network (ESDN) Annual Conference took place. Together with prominent speakers like Angela Merkel and Achim Steiner participants discussed the transformative potential of the EU Green Deal. Stephanie Wunder, Senior Fellow at the Ecologic Institute presented what steps are needed next to implement the Green Deals’ Farm to Fork Strategy. The presentation is available for download.

On 25 September 2020, Dr. Stephan Sina, Senior Fellow at Ecologic Institute, participated as an expert in a hearing of the Bavarian State Parliament’s Committee for Environment and Consumer Protection on the draft of a Bavarian Climate Change Act. Together with nine other experts, he commented on the draft law and answered questions from members of parliament.

We all separate waste. But that is not enough. We have to make sure that garbage is not produced in the first place. All resources have to be recycled again and again in cycles. At the Sustainability Forum of Neumarkter Lammsbräu, Lisa Fiedler of the VAUDE Sustainability Academy, Prof. Dr. Michael Braungart of Cradle to Cradle, Timothy Glaz of Werner & Mertz GmbH and Hannes Schritt of Ecologic Institute Berlin discussed how fast we have to be to save our planet.
