Christina Roolfs is a member of the Policy Instruments Group. She has studied mathematics, and Sustainability Economics & Management and is now doing her doctorate in economics at the nexus of climate policy and public economics.

Her focus is on the role of fiscal transfers and the beneficial coexistence of national and multinational carbon pricing policies. In her dissertation, she examines federal-like systems as for instance the European Emissions Trading System and its interaction with member states’ policies.

Christina has several years of professional experience in the planning and operation of wind farms and photovoltaics (in particular feed-in resp. congestion management measures, direct marketing, and technical re-adjustments according to EEG amendments). She also dealt with congestion management measures and multinational power grid planning as part of her master's thesis.
