In order to achieve the UNFCCC Paris Agreement goals, climate policies worldwide require considerable ratcheting-up. Policy sequencing provides a framework for analysing policy process dynamics that facilitate ratcheting-up. We apply a sequencing perspective to two key EU climate and energy policies, the Emissions Trading Scheme (ETS) and the Renewable Energy Directive (RED), to comparatively test the empirical relevance of sequencing for single policies - in addition to sequencing across policies, which has been the focus of sequencing theory so far - and to uncover specific mechanisms. Our results confirm that sequencing, based on triggering positive and controlling negative feedback, is relevant both within and across policies. Policy choices that may facilitate ratcheting-up include tools to control costs, the possibility to centralise and harmonise in a multi-level governance context, options for compensation of reluctant actors, and the encouragement of learning processes.
Unter den Stichworten "Sektorenkopplung" und "Power-to-X" werden derzeit viele Möglichkeiten der direkten und indirekten Elektrifizierung großer Teile der Endenergienachfrage intensiv diskutiert. In diesem Zusammenhang hat die Diskussion um Wasserstoff als Endenergieträger sowie als Feedstock für die Herstellung von synthetischen Kraftstoffen und chemischen Grundstoffen zuletzt stark an Bedeutung gewonnen. Insbesondere der klimaneutrale Umbau der Grundstoffindustrien und hier vor allem der Grundstoffchemie und der Stahlindustrie würde bedeutende Mengen an grünem Wasserstoff benötigen, die räumlich stark auf die großen Industriekerne fokussiert wären. Ein zeitnaher Einstieg in die Schaffung entsprechender Erzeugungskapazitäten und Infrastrukturen könnte dazu führen, dass Wasserstoff - neben erneuerbaren Energien und Energieeffizienz - zum dritten Standbein der Energiewende avanciert.
Green hydrogen will play a key role in building a climate-neutral energy-intensive industry, as key technologies for defossilising the production of steel and basic chemicals depend on it. Thus, policy-making needs to support the creation of a market for green hydrogen and its use in industry. However, it is unclear how appropriate policies should be designed, and a number of challenges need to be addressed. Based on an analysis of the ongoing German debate on hydrogen policies, this paper analyses how policy-making for green hydrogen development may support industry defossilisation. For the assessment of policy instruments, a simplified multi-criteria analysis (MCA) is used with an innovative approach that derives criteria from specific challenges. Four challenges and seven relevant policy instruments are identified. The results of the MCA reveal the potential of each of the selected instruments to address the challenges. The paper furthermore outlines how instruments might be combined in a policy package that supports industry defossilisation, creates synergies and avoids trade-offs. The paper's impact may reach beyond the German case, as the challenges are not specific to the country. The results are relevant for policy-makers in other countries with energy-intensive industries aiming to set the course towards a hydrogen future.
Despite Germany's Paris Agreement pledge and coal exit legislation, the political debate around carbon-intensive coal remains heated. Coal power and mining have played an important, yet changing role in the history of German politics. In this paper, we analyze the entire parliamentary debate on coal in the German parliament (Bundestag) from its inception in 1949 to 2019. For this purpose we extract the more than 870,000 parliamentary speeches from all protocols in the history of the Bundestag. We identify the 9167 speeches mentioning coal and apply dynamic topic modeling – an unsupervised machine learning technique that reveals the changing thematic structure of large document collections over time - to analyze changes in parliamentary debates on coal over the past 70 years. The trends in topics and their varying internal structure reflect how energy policy was discussed and legitimized over time: Initially, coal was framed as a driver of economic prosperity and guarantee of energy security. In recent years, the debate evolved towards energy transition, coal phase-out and renewable energy expansion. Germany’s smaller and younger parties, the Greens and the Left Party, debate coal more often in the context of the energy transition and climate protection than other parties. Our results reflect trends in other countries and other fields of energy policy. Methodologically, our study illustrates the potential of and need for computational methods to analyze vast corpora of text and to complement traditional social science methods.
Deutschland soll bis 2045 klimaneutral werden. So steht es im verschärften Klimaschutzgesetz, das im Juni 2021 vom Bundestag verabschiedet wurde. Die deutsche Industrie verursacht derzeit knapp ein Viertel der Treibhausgasemissionen, etwa ein Drittel davon entfällt auf die Eisen- und Stahlproduktion. Um das Klimaziel zu erreichen, müssen somit große CO2-Einsparungen in der Stahlindustrie realisiert werden.
