In 2023, the EU adopted regulations defining under which conditions green hydrogen is considered as fully renewable and the methodology to determine the GHG intensity of hydrogen and other PtX products. To discuss these requirements with stakeholders from third countries considering to export renewable hydrogen or derivates to the EU, the International PtX Hub organized a workshop series in 2023. Raffaele Piria coordinated the conception of these workshops and gave a presentation on the climate and energy policy context for the EU's hydrogen strategies and policies.

On 23 November 2022, Dr. Stephan Sina, Senior Fellow at Ecologic Institute, participated as an expert in a hearing of the Hessian State Parliament's Committee for Environment, Climate Protection, Agriculture and Consumer Protection on the Government draft of a Hessian Act on the Promotion of Climate Protection and Adaptation to the Consequences of Climate Change. Together with about 40 associations and experts, he commented on the draft law and answered questions from members of parliament.

Ewa Iwaszuk, a Fellow at Ecologic Institute, held a presentation "Policy instruments to promote implementation of nature-based solutions" at a side-event "Nature-based solutions for building performance" during the global climate conference COP27 in Sharm-el-Sheikh (Egypt). Ewa's presentation made the case that policy instruments and their governance act as critical enablers or barriers to adoption of nature-based solutions. She presented the Urban Governance Atlas that Ecologic Institute is currently developing in the frames of the INTERLACE project and discussed good practice examples of policy instruments from around the world that support the implementation of nature-based solutions at a building level.

From 7 to 19 December 2022, the international community is scheduled to come together to discuss the future of the Convention on Biological Diversity. One of the key items that will be negotiated at the upcoming COP15 is the post-2020 Global Biodiversity Framework. In the light of these upcoming negotiations on 2 November 2022, the Guarini Center on Environmental, Energy and Land Use Law at New York University School of Law and the German Consulate General in New York organized an event with experts from New York City and Berlin to discuss the role of local governments in implementing global biodiversity targets, including the ways in which cities can support urban biodiversity. Sandra Naumann, Senior Fellow at the Ecologic Institute, presented Berlin's strategy to promote urban biodiversity and participated in the final panel.

During this webinar, Ecologic Institute's Dr. Nico Stelljes presented the highlights and the findings of the project "Indicators of an Integrated German Marine Policy" and gave an overview of a possible set of indicators to assess an integrated maritime policy at a national level, with the scope to stimulate discussions on similarities and differences in the integrated approaches to the maritime economy in the Baltic Sea Region.

In her presentation, titled "Evaluating environmental policies with citizen science data? An example from the Plastic Pirates investigating plastic pollution of rivers", Linda Mederake (Ecologic Institute) presented an approach to evaluate the Single-Use Plastics Directive with the help of citizen science data.

From 21 to 22 September 2022, the INTERLACE project held the first European Cities Talk Nature Engagement Event in Kraków (Poland). Sandra Naumann, Coordinator of the INTERLACE project and Senior Fellow at Ecologic Institute, opened the conference by presenting the INTERLACE project and its work on the ground to the audience.

McKenna Davis, Senior Fellow at Ecologic Institute, held a keynote speech at the conference "Designing Urban Spaces with Nature" on 7 September 2022 in Eindhoven (the Netherlands). She spoke about the integration of nature-based solutions (NBS) across key European policy initiatives as a framework for enhancing local NBS action, building on her work for the European Environmental Agency and Naturvation project. She also highlighted good practice examples of policy instruments supporting NBS in the Netherlands, which are part of the Urban Governance Atlas currently being developed within the INTERLACE project.

Dr. Stephan Sina, Senior Fellow of Ecologic Institute, gave a speech at the international academic conference "Towards the Polish Climate Protection Act" on 7 September 2022 in Szczecin (Poland). He presented the main features of the German Federal Climate Change Act and its revision based on the decision of the Federal Constitutional Court on 24 March 2021. He also participated in the panel discussion.

On 16 and 17 August 2022, the 3rd International Forum on Urbanism – Portoviejo Vision 2035, for urban development and design of cities on a human scale with a focus on climate change, was held in the Las Vegas Park in the city of Portoviejo. Natalia Burgos Cuevas, Researcher at Ecologic Institute, was invited as keynote speaker to talk about on the promotion of nature-based solutions in Latin America drawing on the insights gathered from the Urban Governance Atlas, developed in INTERLACE.

The biodiversity and climate crises are increasingly threatening planetary biodiversity and dependent livelihoods. Linkages between these two crises are already recognised by science and policy, but they are still not sufficiently addressed in integrated manner in practice. Nature-based solutions (NBS) and ecosystem-based approaches have the potential to enhance these synergies and deliver multiple benefits for ecosystems, biodiversity, climate change mitigation and adaptation, human well-being among other objectives. This topic was explored during the "International workshop on strengthening synergies for biodiversity and climate in multifunctional landscapes", organized by the German Federal Agency for Nature Conservation (BfN). Sandra Naumann, Senior Fellow at the Ecologic Institute, was a keynote speaker, presenting on the potential but also limitations of NBS to achieve climate and biodiversity goals.

On 4 July 2022, McKenna Davis from the Ecologic Institute spoke to the 2nd step of this methodology: EXPLORING existing urban greening policies, plans and regulations to identify gaps and understand local needs. Representing the CLEVER Cities project, she provided insights on how to ensure coherent and coordinated policymaking and align objectives across sectors and policies. She also highlighted relevant EU policies and initiatives supporting nature-based solutions to contextualise local action towards NBS mainstreaming.

On 22 June 2022, experts from various disciplines exchanged views on the transformation of the food system towards a more plant-based diet. More than 400 interested participants attended the event, which is part of the National Dialogue on Sustainable Food Systems in the context of the UN Food Systems Summit.
