Abstract: The existing "Jamieson’s Principles"、"Oxford Principles" and "Tollgate Principles" in geoengineering define its responsibility subject and action framework clearly. Nevertheless, they make slightly insufficient ethical requirement for the experimental process and actual deployment and ignore the realistic problems on how to deal with negative effects made by geoengineering. Responsible stagnation, a new concept proposed in the questioning of responsible innovation research, is a protection mechanism. Firstly, it criticizes meaningless experimental projects that deviates from human well-being at macro level, advocating that innovations stem from responsibility; secondly, it requires that in extreme cases, social and extremely dangerous Innovation activities be stagnated so as to ensure human safety and buy time to nurture effective responses. Finally, it requires, at micro level, the responsibility-oriented experimental design to be reconstructed, experimental deployment with moral constraints to be deconstructed and a solid law for resolving crises with stagnation as the dual guidance to be constructed. The principle of responsible stagnation makes up for the lack of ethical guidance and remedial measures for the existing principles of geoengineering in the process and result stages.
