Dr. Mirjam Kosch

Postdoctoral Researcher

"In 2050, I will be 65 years old and looking forward to my retirement. In the same year, at the latest, we must achieve net zero greenhouse gas emissions in order to limit global warming. It is my professional goal to be able to say at my retirement: The world has managed to stop global warming - and I have contributed to it!"

Mirjam Kosch is an enthusiastic environmental scientist and completed her doctorate in economics at ETH Zurich on climate policy in the electricity sector. As part of her doctoral thesis, she empirically analyzed the impact of renewable energy subsidies and carbon pricing. Currently, she is working on the expansion of the European emissions trading system and investigating the interplay of different policy instruments as well as the impact of climate policy on electricity prices. In addition, Mirjam Kosch is actively engaged in the dialogue between science and politics.
