Climate impacts and energy transitions

The control of polluting emissions is an perpetual question in the literature of environmental economics. Different economic settings require different tools and strategies to efficiently keep pollution under control. Stefan Wrzaczek together with international colleagues analyses these strategies within two different settings: (i) Management of the tragedy of commons and polluting emissions through taxation in different market settings. (ii) Pollution control under catastrophic climate change as a differential game.

Deep decarbonization of energy systems is a key step to restrict the global temperature rise to “well below 2 °C”. Majority of global net-zero emission scenarios emphasize on the large-scale deployment of Carbon dioxide removal (CDR) technologies like bioenergy with carbon capture and storage (BECCS) to meet the global climate goals.

Their have been numerous empirical studies on the specific household characteristics correlated with the different components of disaster risk, i.e. exposure and vulnerability. In cooperation with colleagues from POPJUS and the TU Wien, Michael Freiberger establishes a dynamic household model, which explains the behavior with respect to the risk of natural disasters based on their inherent preferences. This theoretical model is essential for the realistic assessment of policy interventions, as it allows for a projection of intrinsically motivated reactions of households to potential policy interventions.

Integrated Assessment Models (IAMs) attempt to capture and describe the interactions of (i) human behaviour, (ii) economic activity, and (iii) and climate dynamics and impacts. However, IAMs are often treated as some sort of black-box when calculating solutions. Researchers of the Economic Frontiers Program try to investigate established IAMs from an analytical perspective and generate new insight and illuminate the black-boxes.
