Some of them contend that international public officials have gained significant political influence in various policy fields. Compared to other international bureaucracies, the political leeway of the Secretariat of the United Nations Framework Convention on Climate Change has been considered rather limited. Due to the specific problem structure of the policy domain of climate change, national governments endowed this intergovernmental treaty secretariat with a relatively narrow mandate. However, this article argues that in the past few years, the United Nations Framework Convention on Climate Change Secretariat has gradually loosened its straitjacket and expanded its original spectrum of activity by engaging different sub-national and non-state actors into a policy dialogue using facilitative orchestration as a mode of governance. The present article explores the recent evolution of the United Nations Framework Convention on Climate Change Secretariat and investigates the way in which it initiates, guides, broadens and strengthens sub-national and non-state climate actions to achieve progress in the international climate negotiations.
Points for practitioners
The Secretariat of the United Nations Framework Convention on Climate Change has lately adopted new roles and functions in global climate policymaking. While previously seen as a rather technocratic body that, first and foremost, serves national governments, the Climate Secretariat increasingly interacts with sub-national governments, civil society organizations and private companies to push the global response to climate change forward. We contend that the Climate Secretariat can contribute to global climate policymaking by coordinating and steering the initiatives of non-nation-state actors towards coherence and good practice.}, language = {en} } @article{HickmannLederer2020, author = {Hickmann, Thomas and Lederer, Markus}, title = {Einleitung: Harald Fuhr - vision{\"a}rer Grenzg{\"a}nger mit Leidenschaft, Eingebung und Augenmaß}, series = {Leidenschaft und Augenmaß : sozialwissenschaftliche Perspektiven auf Entwicklung, Verwaltung, Umwelt und Klima : Festschrift f{\"u}r Harald Fuhr}, journal = {Leidenschaft und Augenmaß : sozialwissenschaftliche Perspektiven auf Entwicklung, Verwaltung, Umwelt und Klima : Festschrift f{\"u}r Harald Fuhr}, publisher = {Nomos}, address = {Bade-Baden}, isbn = {978-3-8487-5249-2}, pages = {13 -- 21}, year = {2020}, language = {de} } @incollection{LedererHoehneStehleetal.2020, author = {Lederer, Markus and H{\"o}hne, Chris and Stehle, Fee and Hickmann, Thomas and Fuhr, Harald}, title = {Multilevel climate governance in Brazil and Indonesia}, series = {Climate governance across the globe : Pioneers, leaders and followers}, booktitle = {Climate governance across the globe : Pioneers, leaders and followers}, editor = {Wurzel, R{\"u}diger K.

The chapter focuses especially on the role of multilevel governance in bringing about pioneership and leadership and on the different types of that have emerged. It also explores whether and, if so, to what extent domestic pioneers and leaders attract followers and whether there are signs of sustained domestic leadership. The chapter identifies the actors that constitute pioneers and leaders and assesses the processes which lead to their emergence. The chapter authors take up Wurzel et al.'s (2019) call to open up the black box of the nation-state. But instead of stressing the role of non-state actors, the chapter authors focus on vertical interactions among different governmental levels within nation states. The main argument put forward is that international and transnational processes, incentives, and ideas often trigger the development of domestic pioneership and leadership. Such processes, however, cannot be understood properly if domestic politics and dynamics across governmental levels within the nation-state are not taken into account.}, language = {en} } @article{HoehneFuhrHickmannetal.2018, author = {H{\"o}hne, Chris and Fuhr, Harald and Hickmann, Thomas and Lederer, Markus and Stehle, Fee}, title = {REDD plus and the reconfiguration of public authority in the forest sector}, series = {Global Forest Governance and Climate Change}, journal = {Global Forest Governance and Climate Change}, editor = {Nuesiri, Emmanuel O.}, publisher = {Palgrave}, address = {Basingstoke}, isbn = {978-3-319-71946-7}, doi = {10.1007/978-3-319-71946-7_8}, pages = {203 -- 241}, year = {2018}, abstract = {Since the 1980s, central governments have decentralized forestry to local governments in many countries of the Global South.

They have shown that various new carbon governance arrangements have emerged, which operate simultaneously at different governmental levels. However, despite the numerous descriptions and mapping exercises of these governance arrangements, we have little systematic knowledge on their workings within national jurisdictions, let alone about their impact on public-administrative systems in developing countries. Therefore, this article opens the black box of the nation-state and explores how and to what extent two different arrangements, that is, Transnational City Networks and Reducing Emissions from Deforestation and Forest Degradation, generate changes in the distribution of public authority in nation-states and their administrations. Building upon conceptual assumptions that the former is likely to lead to more decentralized, and the latter to more centralized policy-making, we provide insights from case studies in Indonesia, South Africa, Brazil, and India. In a nutshell, our analysis underscores that Transnational City Networks strengthen climate-related actions taken by cities without ultimately decentralizing climate policy-making. On the other hand, Reducing Emissions from Deforestation and Forest Degradation tends to reinforce the competencies of central governments, but apparently does not generate a recentralization of the forestry sector at large.}, language = {en} } @article{Lederer2012, author = {Lederer, Markus}, title = {Klimapolitik zwischen Kyoto und Canc{\´u}n}, series = {Klimapolitik International}, journal = {Klimapolitik International}, editor = {Kleinw{\"a}chter, Kai}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1868-6222}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-81364}, pages = {83 -- 92}, year = {2012}, abstract = {In diesem einleitenden Beitrag des Themenschwerpunktes wird der Hintergrund der internationalen Klimaverhandlungen erl{\"a}utert und die Ergebnisse des Kopenhagen-Akkords vorgestellt.

In contrasting this to REDD+, the hypotheses are advanced that (i) output-oriented legitimacy/effectiveness can again be achieved but that (ii) a higher degree of input-oriented legitimacy is necessary for REDD+ and thus also a certain trade-off between the two forms of legitimacy can be expected.
