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.

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. At the event, we want to explain why it is necessary to ambitiously refurbish the energy efficiency of these areas, that this can also be beneficial for tenants in the medium term, and that these areas therefore even represent an opportunity for socially acceptable energy efficiency refurbishments. The districts are an important actor here — what options do they have for action to promote ambitious climate protection in these areas and beyond in neighbourhoods in general without neglecting the protection of tenants? In the seventh edition of Wandelwecker, our morning impulse for a social and ecological metropolis, we discuss this with two proven experts: Jörg Zander, District Office Charlottenburg-Wilmersdorf Dr. Julika Weiß, Institute for Ecological Economy Research (IÖW)

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.
