Zurich, Switzerland, 12 April 2017 - Fighting increasing air pollution in cities in a concentrated manner
requires an extensive amount of data. For the first time, as part of a pilot project in Nuremberg, an
innovative method has been developed to enable the analysis of traffic flows and, subsequently, air
quality, by using anonymised mobile network data. The project is a collaboration between sustainability
expert South Pole Group, Telefónica NEXT, the data analysis expert Teralytics and the city of
Nuremberg. Supported by the EU programme Low Carbon City Lab (LoCaL) under the Climate-KIC,
the new methodology will be further developed in a follow-up project.
Spearheading smart, tailor-made climate solutions
The accurate measurement of CO2 and short-lived air pollutants in cities is a complex task. Through the
pilot project in Nuremberg, South Pole Group has, together with the project partners, developed
an entirely new approach to assist cities in measuring and mapping out rapidly increasing
emissions. The basis of the approach was mobile network data generated in August and September
2015 in the Telefónica Deutschland network. Using a three-level, TÜV-certified process, said data was
fully anonymised; all personal information has been removed. The data analysis expert Teralytics
transformed the data into mobility flows using their unique algorithms, thus identifying over 1.2 million
routes. Finally, South Pole Group used a dispersion model to model the pollution levels, doing so by
taking into consideration information on pollutants from individual traffic carriers from the Federal Ministry
for the Environment and meteorological data. This new method will significantly contribute to ensuring
more focused climate protection in the urban space
"Approximately 70 percent of global greenhouse gas emissions are generated in cities, meaning that they
play a key role in climate protection. We see great potential in the use of daily generated data, such as
mobile network data, to reduce pollution levels in cities. Data-based analyses and innovative measures
can contribute to even more efficient support for cities in future for the implementation of their ambitious
climate and clean air objectives", states Renat Heuberger, CEO of South Pole Group.
The pilot project helps to inform decision-makers in Nuremberg to create tailor-made solutions to best
counter hotspots by, for example, having means of transport with high emissions replaced with low-carbon
alternatives. Being able to compare current data to data from 2015 will also allow project partners to evaluate the effectiveness of measures taken to combat poor air quality.
"We are very interested in improving the air quality in our city of Nuremberg and are very open to new methods to achieve this. Accordingly, we were very pleased to support this research project as a pilot city. Especially relevant for us are the findings as to how we can situationally better manage traffic. The findings obtained as part of the pilot project could lead to a realistic assessment of such regulation mechanisms. Additionally, further research efforts are planned to be geared towards the examination of traffic-minimising measures. We will continue to eagerly follow the development of further research with mobile network data", says Dr Peter Pluschke, City Councillor and Head of the Department for Environmental Policy and Health.
Maximilian Groth, Business Developer at Teralytics, says: "Algorithms often appear very abstract. This
joint pilot project shows how, with the help of data and algorithms, real social issues and challenges can
"The pilot project in Nuremberg has clearly shown the specific added value of anonymised mobile network data for the environment. This is data from people for people. We see great potential in the results and will start the next phase of our research. The goal is to develop a product that German cities, German statesand the German federal government can use to better face the challenges of emissions pollution," emphasises Florian Marquart, Managing Director of Telefónica NEXT for Advanced Data Analytics.
Further development of innovative methodologies to reduce urban emissions
Measures to reduce emissions at city-level can create the necessary tipping point to reach climate change
mitigation goals and sustainable economic growth. Following the successful conclusion of the pilot project
in Nuremberg, the project team will expand and improve the methodology in a second research project in
order to improve the accuracy of the results. This project will also be developed under the Low Carbon
"Creating strategy to design inclusive, sustainable, and low-carbon cities is a collaborative effort. We're
excited to put our expertise in results-based, climate-smart city solutions to work to take this project
forward," says Denis Jorisch, Project Lead, South Pole Group. "Each urban challenge is different,
which is why it is important to tailor monitoring and advisory solutions for cities."
Victor Gancel, Programme Manager of the Low Carbon City Lab (LoCaL) of Climate-KIC continues:
"We are pleased that the pilot project has provided such extensive data. We want to continue to financially
support the project, thereby contributing to helping cities improve their air quality in a targeted manner in
