Berlin can be climate-neutral until 2050: Feasibility Study


Berlin can reduce its CO2 emissions from presently about 21 million tons to 4.4 million tons in 2050 – despite economic growth and population increase. This would mean a reduction of about 85 percent compared to the basis year 1990 and complies with the ambition to make Berlin a climate-neutral city. As a positive side-effect, there could be a regional economic effect of up to 138 million euro from the shift in the energy supply from fossil to mainly renewable energy sources.

On behalf of the Berlin Senate Department for Urban Development and the Environment, a consortium led by the Potsdam Institute for Climate Impact Research (PIK) analyzed scenarios and developed recommendations how to achieve climate-neutrality.

The study will be presented to the public today in the Berlin town-hall by Michael Müller, Senator for Urban Development and Environment, and Prof. Dr. Dr. h.c. Hans Joachim Schellnhuber, Director of PIK.

When in 2011 the Berlin governing coalition decided to make Berlin a climate-neutral city until 2050, a report was needed to analyze the feasibility of this political goal and map out possible pathways to achieve it. A team of eight research and advising institutes led by PIK now made strategic suggestions after conducting a comprehensive analysis and scenario computing.

Partners of PIK are the Institute for Ecological Economy Research (IÖW), the energy consulting office BLS Energieplan, the Berlin office for urban development UmbauStadt, the Innovation Centre for Mobility and Societal Change (InnoZ), the Potsdam office Aerial Image, Environment and Planning LUP, the landscape architect office bgmr and the lawyers office HFK advocates. 

The main results of the study are presented today in a public event in the Berlin town-hall by Dr. Fritz Reusswig (PIK, project management) and Prof. Dr. Bernd Hirschl (IÖW, deputy project management).

If we want to avoid dangerous climate change, we have to act quickly and determined. .

The Berlin Senator for Urban Development and Environment, Michael Müller, highlights the important role of the feasibility study for Berlin’s future energy and climate politics. “The debates on energy and climate politics have intensified over the last few months – let me just mention the public discussion on the creation of a municipal utility and the re-municipalization of the energy networks. Both are important bases for a climate neutral Berlin as well.” The feasibility study shows that it is possible to achieve this goal, and describes possible pathways for the development of the sectors of the city relevant for emissions based on different scenarios.

The most important sphere of activity is the buildings sector. In the future, heating would have to be generated more from natural gas and biomass than from coal or oil. An increase of the regenerative part in natural gas (i.e. by surplus electricity) therefore plays a major role.

In the power sector, solar energy will be a key technology. With an improvement in energy efficiency, Berlin would even be able to generate more electricity than it needs. Until 2050, Berlin could thus be a net exporter of mostly regenerative electricity. Lignite from Brandenburg would not be needed anymore, but regional wind energy in the winter. The second most important sector is transport. Different transport vehicles and systems have to be cross-linked better. This also includes an increase of electric vehicles to achieve the climate target.

“The transformation of the energy system would mean investments that could strengthen the Berlin economy considerably,” says Bernd Hirschl from IÖW. The study also numbers the remarkable local effects for value creation and employment by a shift to climate neutrality of the Berlin energy industry. Depending on the scenario, until 2050, regional economic effects of 67 to 138 million euro a year could be generated.

Senator Michael Müller emphasizes that the study picks up on the inter-relations of ecologic, economic and social aspects. Michael Müller: “I really appreciate that the consortium led by PIK dealt sensitively with the affordability of important measures – especially in regard to energy related modernization and renovation and the development of rent progression in our city.”

Given the long-term character of the goal to become climate neutral, Senator Müller also welcomes suggestions for flagship projects and measures, which can be initiated today. “This supports our efforts to get under way with new measures even before the integrated energy and climate concept is at hand, while the development of the concept will start this year.”

The feasibility study will be available here (in German):

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
