In this research project for the German Federal Environment Agency, Ecologic Institute develops specific proposals for the governance of the main currently discussed geoengineering concepts at the international level. Based on a comprehensive analysis of the existing regulatory framework and its gaps, the study identifies general options and specific recommended actions for the effective governance of geoengineering. A key consideration is that the recommendations can be implemented in practice. First, the study explores whether and to what extent it is useful and feasible to have a single definition of geoengineering for governance purposes. It then analyses the existing governance of geoengineering in international law, with a brief overview of EU and German law. On this basis, it develops specific regulatory options and proposals. We analyse why governance of geoengineering should be pursued and develop specific proposals how such governance should be designed. We first make explicit the objectives and functions that governance of geoenginering is to fulfil. The geoengineering debate for the most part has not addressed this issue. Second, we derive core elements of appropriate governance design from these objectives and criteria. Third, we assess which geoengineering techniques require international governance on the basis of the objectives and criteria. Fourth, we identify governance gaps where the existing international framework does not correspond to our proposed core governance elements. Fifth, we make proposals to fill the governance gaps. Kurzbeschreibung Die Diskussion um Geoengineering als mögliche Option der Klimapolitik gewinnt zunehmend Aufmerksamkeit an der Schnittstelle zwischen Wissenschaft und Politik. In diesem Forschungsprojekt für das Umweltbundesamt entwickelt das Ecologic Institut konkrete Vorschläge für die Governance der gegenwärtig diskutierten Geoengineering-Konzepte auf internationaler Ebene. Auf Grundlage einer umfassenden Analyse des bestehenden Regelungsrahmens und seiner Lücken entwickelt diese Studie allgemeine Optionen und konkrete Handlungsempfehlungen für die wirksame Governance von Geoengineering. Ein zentrales Anliegen ist, dass die Empfehlungen praktisch umsetzbar sind. Die Studie erörtert zunächst, ob und inwieweit es sinnvoll und durchführbar ist, eine einzige Definition von Geoengineering als Grundlage von Governance zu nehmen. Sie untersucht die bestehende Governance von Geoengineering im internationalen Umweltrecht, und gibt einen kurzen Überblick des EU und deutschen Rechts. Auf dieser Grundlage entwickelt sie konkrete Regulierungsoptionen und -vorschläge. Wir analysieren, warum Governance von Geoengineering angestrebt werden sollte, und entwickeln konkrete Vorschläge, wie solche Governance gestaltet werden sollte. Wir legen zuerst ausdrücklich die Ziele und Kriterien dar, die die Governance von Geoengineering erfüllen soll. Die bisherige Diskussion zu Geoengineering hat sich meist nicht damit befasst. Zweitens leiten wir aus diesen Zielen und Kriterien Kernelemente einer angemessenen Governancestruktur ab. Drittens bewerten wir auf Grundlage der Ziele und Kriterien, für welche Geoengineering-Konzepte internationale Governance erforderlich ist. Viertens identifizieren wir Regelungslücken, wo der bestehende internationale Regelungsrahmen nicht den von uns vorgeschlagenen Kernelementen der Governance entspricht. Fünftens machen wir Vorschläge, wie diese Governancelücken auszufüllen sind. 5 Options and Proposals for the International Governance of Geoengineering 6 Options and Proposals for the International Governance of Geoengineering Table of Contents Table of Contents .................................................................................................................................... 7 List of Abbreviations .............................................................................................................................10 1 Summary ..........................................................................................................................................13 1.1 Definition of geoengineering ..............................................................................................13 1.2 The existing legal framework ..............................................................................................14 1.2.1 International Law .............................................................................................................14 1.2.2 Conclusions on existing international governance......................................................18 1.2.3 European Law and German Law ....................................................................................18 1.3 Regulatory options and proposals .......................................................................................19 2 Zusammenfassung ..........................................................................................................................25 2.1 Definition von Geoengineering ...........................................................................................25 2.2 Der bestehende Regelungsrahmen .....................................................................................27 2.2.1 Völkerrecht ........................................................................................................................27 2.2.2 Bewertung bestehender internationale Governance ...................................................31 2.2.3 Europäisches und deutsches Recht ................................................................................31 2.3 Regelungsoptionen und -vorschläge ...................................................................................32 3 Introduction .....................................................................................................................................38 4 Definition of geoengineering ........................................................................................................40 4.1 Definitional context...............................................................................................................40 4.2 Existing definitions ................................................................................................................40 4.3 Activity ....................................................................................................................................42 4.4 Intent .......................................................................................................................................43 4.5 Purpose ...................................................................................................................................44 4.6 Scale .........................................................................................................................................45 4.7 Conclusions.............................................................................................................................46 5 The existing legal framework ........................................................................................................49 5.1 International Law ..................................................................................................................49 5.1.1 Introduction ......................................................................................................................49 5.1.2 Cross-cutting general rules ..............................................................................................50 5.1.3 Stratospheric aerosol injection .......................................................................................60 5.1.4 Cloud brightening from ships ........................................................................................74 5.1.5 Desert reflectors ................................................................................................................78 5.1.6 Installations in outer space .............................................................................................80 7 Options and Proposals for the International Governance of Geoengineering 5.1.7 Carbon
