"This paper provides a comprehensive overview and analysis of different options to reform the EU Emissions Trading System (ETS). The options discussed include changes to address the rigidity of supply on the auctioning side, as well as reforms to add flexibility to free allocation. Additionally, other options that may enhance the functionality of the EU ETS are covered, drawing on examples and practices in other carbon-pricing mechanisms around the world.

It is crucial to note that any reform of the EU ETS must consist of a package of options. Taken separately, the options may very well have beneficial effects, but they would also leave intact clear imperfections in the current design. Specifically where the auctioning supply mechanism and the flexibility in free allocation are concerned, we assess multiple options in each category, and present evidence for each option. Where appropriate, we suggest complementing these reform options with additional elements (presented in section 3.3).

The aim of any structural reform should be to arrive at a set of options that forms a consistent and credible package. With this paper, we provide an evidence-based assessment of the various building blocks of such a reform."

"One of the lessons learned from the German effort under the heading of Energiewende is the insight that simply shifting to renewables and recommending improving energy efficiency is not sufficient to lower greenhouse gas emissions. Combined with the expected radical change of technologies this requires a more profound understanding of our energy systems. Therefore, in contrast to most conventional approaches we propose a deepened structural analysis that covers the full energy value chain from the required functionalities for mechanical, thermal and specific electric energy services via application and transformation technologies up to primary energy. This deepened structural approach opens and substantially enhances our understanding of policy designs that are compatible with the Paris Agreement and Sustainable Development Goals. We discover the essential role of four energy grids, namely for electricity, heat, gas, and information as the key for integrating all components of a newly structured energy system. Consequently, we conclude that policy strategies focusing on individual components of an energy system as simply shifting to renewables may from a comprehensive perspective on sustainability in the worst case even turn out as counterproductive."
