Climate Neutrality in Cities

Moderator: Prof. Ingo Stadler

In transition processes towards achieving climate neutrality large cities and urban areas represent with high population densities and high energy densities a special challenge. On this panel we would like to discuss amongst researchers and representatives from cities different solution pathways, barriers and how to overcome them. We want to present and discuss best practice solutions.

Şiir KILKIŞ is alumna of KTH Royal Institute of Technology, School of Architecture and the Built Environment, Faculty of Civil and Architectural Engineering, and Georgetown University, where she graduated magna cum laude as the gold medalist in Science, Technology, and International Affairs. She is a member of the International Scientific Committee of the SDEWES Center, a Lead Author of the IPCC Sixth Assessment Report (AR6) for “Urban Systems and Other Settlements,” Associate Professor in Energy Systems Engineering, and Senior Researcher and Advisor to the President at the Scientific and Technological Research Council of Turkey with specialization in sustainable urban systems. In her research work, she developed and applied a SDEWES Index to benchmark cities towards sustainable urban systems, analyzed sustainable campuses, deployed a novel net-zero district concept for the pilot project of the Östra Sala backe district in Uppsala Municipality in Sweden, and developed the Rational Exergy Management Model (REMM) to provide guidance to curb CO₂ emissions in the built environments of the future. During her twelve year work experience, she contributed to national policies on science, technology and innovation, coordinated technology roadmaps, served as a delegate to the UN, and led R&D and innovation study visits to Singapore, China, Brazil, and India. She is lecturer of courses in graduate programs on Energy Engineering and Earth System Science. She has been actively involved in International Energy Agency Annex 64 on “Optimised Performance of Energy Supply Systems with Exergy Principles,” authored numerous publications in SCI journals, a chapter on “Green Cities and Compound Metrics Using Exergy Analysis” in the Encyclopedia of Energy Engineering and Technology, and co-authored a book on Cogeneration with Renewable Energy Systems.


Benchmarking the performance of cities across energy, water and environment systems
related metrics presents an opportunity to trigger policy learning, action, and cooperation to bring cities closer to sustainable development.
