The economies and populations that are the main contributors to the climate crisis are least affected by the consequences. People in the Global South are already exposed to drought, forest fires, flooding and water shortages. According to the UN, there were some 270 million migrants worldwide in 2020. Recent forecasts predict that the climate crisis will force up to 1.2 billion people to leave their home countries by 2050. On 1 December 2021; the issue of "Migration and Climate Crisis: Challenges and Perspectives" was discussed. The discussion based on inputs by Writer Parag Khanna and human rights and environmental activist Kumi Naidoo from South Africa. The full recording of the event is available online.

Berlin has set ambitious standards for the prevention of CO2 emissions, with significantly stricter targets in the new Climate Protection Act (EWG Bln). What are the targets and opportunities, and what are still the major challenges and barriers? In order to become climate-neutral, it is imperative that the building sector be given greater consideration. The Climate Protection Act and the Berlin Energy and Climate Protection Program (BEK) 2030 emphasize the exemplary role of the public sector in this area. This means that public buildings such as school buildings are a key factor. In the districts' renovation roadmaps, schools sometimes account for more than 80 percent of the buildings that need to be renovated for energy efficiency in the next few years.

As part of the STErn project led by Ecologic Institute, an online-workshop on the socio-ecological transformation of the food system in Germany with a focus on the protein transition took place on 30 November 2021 together with 35 experts in that field. The aim of the event was to discuss possible indicators that can help to politically anchor and monitor the necessary change in dietary patterns towards more plant-based and less animal-based proteins.

On the 25 November 2021, more than 70 actors dealing with food waste reduction in Germany met for an exchange on how to plan and implement measures that create an impact. The event was part of the so-called "Dialogue Forum Private Households" that is part of the German Strategy for Food Waste Reduction.

With the Fit for 55 package, the European Commission made far-reaching proposals in July 2021 to align the architecture of European climate policy with the goal of climate neutrality. These proposals include the strengthening of the existing emissions trading scheme, the introduction of new emissions trading for transport and buildings, a border adjustment mechanism (CBAM) to protect against carbon leakage and the tightening of regulatory instruments for transport and buildings. However, the proposals raise a number of questions – from distributional effects and acceptance to the consistency of the instruments. In the course of this two-day hybrid event, researchers from the Ariadne consortium discussed these issues with stakeholders and decision-makers at the European level.

In the coming years, the course must be set for the necessary transformation toward a society and economy that is in keeping with the needs for future generations. Science, and sustainability research in particular, has a responsibility to support this change with its resources. But what must science resemble in order to find practicable answers to the most urgent questions of the future? And what demands does this place on the research policy agenda? This event is part of the "Knowledge for Change" series of events celebrating Ecornet's 10th anniversary. Ten years ago, leading independent institutes of environmental and sustainability research in Germany joined forces to form the Ecological Research Network (Ecornet) in order to bring their combined knowledge to bear on the scientific landscape and society. With their practice-oriented, transdisciplinary research, the Ecornet institutes have been accompanying - and actively shaping - socio-ecological change for decades.

This virtual conference shared ideas for advancing additional multilateral action in support of the goals of the Paris Agreement and discuss them with international experts.

The economies and populations that are the main contributors to the climate crisis are least affected by the consequences. With the European Green Deal, the EU claims for itself a pioneering role in climate protection, but does it have solutions ready that do justice to the structural inequality and unfair distribution of social, economic and political opportunities between the communities that populate the earth? In the online event on 24 November 2021 the discussion drew on Concepts for Climate Justice, featuring Maria Fernanda Espinosa, Ecuadorian diplomat, politician, academic and former president of the 73rd UN-General Assembly. We are looking forward to your registration. The full recording of the event is available online.

To continue the successful exchange on various aspects of Arctic marine conservation in November 2020, twenty international experts from research and policy came together again in a virtual meeting for the "Arctic Marine Conservation Dialogue" on 17 and 18 November 2021.

Climate change with the resulting global warming is the largest and most all-encompassing global crisis of our time. As an ecological crisis, it stands for the misuse of fossil fuels and the exploitation of natural life-support systems, which includes the destruction of biodiversity and also irreversible damaging impact on the geological sphere. Furthermore, climate change is a geopolitical problem. It is already stoking sociopolitical instability, creating migratory pressure, exacerbating global inequality, endangering human rights and putting peace in the world at risk.

The more stringent climate targets of the state of Berlin require that both the heat supply is converted to renewable energies in the next few years and that the building envelopes are ambitiously renovated to make them more energy efficient. This poses great challenges for the state and districts as well as the real estate industry. At the same time, due to the tense situation on the Berlin housing market, there is a need for regulations to protect tenants, which is why the number of milieu protection areas in Berlin's districts has risen sharply. In these areas, which already contain a relevant proportion of old buildings which are in need of refurbishment, there are additional obstacles to climate protection measures that are in line with the objectives.

Europa its on its way towards a circular economy and has set itself an extremely ambitious plan to this end in the form of the Circular Economy Action Plan; among other things, non-recyclable residual waste is to be halved by 2030. But how is it being put into practice? And what does it take to gain more speed here – for example in the textile sector, which is virtually exemplary for the linear thinking of a throwaway culture.

Infrastructure development in Germany must be increasingly geared towards increased climate targets and the need for decarbonization. At the same time, public participation is still needed to involve the population in the upcoming change processes and to ensure democratic achievements. Thus, leveraging efficiency potentials in planning processes is considered key to manage infrastructure development in a more targeted manner in the years to come. What are the possibilities, limits and sensible approaches to accelerating planning?

Join us on 6 November 2021 at 17:45 CET for this online COP26 Side Event that explores the role of long-term climate strategies in sustainability governance, raising short-term ambition on climate action, ecosystem stewardship and adaptation. The event will be live streamed on YouTube.

Nature-based solutions (NbS) are crucial for cities to jointly address the climate and biodiversity crises, while creating quality green jobs and wellbeing for local communities. This COP26 EU Side Event featured different sector practitioners (policy makers, entrepreneurs, international organizations) delivering inspiring presentations and engaging in a panel discussion highlighting a variety of perspectives on key challenges, opportunities, and pathways to mainstream urban NbS and boost local economies.
