Her key focus is to ensure the use of cost-efficient policy measures on the road towards a sustainable, low-carbon and resource-efficient society. She has been instrumental in fine-tuning the design of the Swedish carbon tax since the 1990s and has been a team leader of energy and climate taxation projects within the Swedish Government Offices since 2001. Her work has included carrying out Green Tax Shift Reforms and developing economic instruments designed to achieve the EU’s targets of reducing greenhouse gas emissions and increased shares of renewable energy.

She serves as Sweden’s lead EU negotiator on energy and climate taxation issues and has worked extensively at EU-level to improve and coordinate the design of EU tax and state aid legislation to better reflect the Polluter Pays Principle and encouraging Member States to increasingly use environmental taxes. In a broader international context she has presented and debated carbon tax experiences before the UN Tax Committee and the COP conferences on climate under the UNFCC, as well as participated in a number of international conferences.  Her ability to build and maintain net-works with a great number of colleagues among Government officials as well as representatives from academia and stakeholders has served her well in giving a broad understanding of how various issues and political agendas are interlinked.
