The climate change factor (CCF) is a precautionary instrument for technical flood protection that was introduced in Southern Germany in the early 2000s. The CCF was designed as a surcharge value to be added to all new technical flood protection facilities, such as dams, protection walls, and retention areas. This paper deconstructs the conditions and processes that led to the creation of this new policy instrument. Following the instrument choice framework, the paper analyzes in a heuristic manner, the institutions, actors, discourses, and decision context that were part of this process from the early 1990s to 2004, when the instrument was introduced. In order to better understand the scope of this regional instrument, the paper also briefly depicts four non-representative cases of flood risk and protection management, where the instrument was either applied or avoided. The article closes with an assessment of the CCF, concluding that the innovativeness of this instrument faded once the overarching sectoral paradigm shifted from technical flood protection to more comprehensive flood risk management.

渐进式政策工具的兴衰：德国南部的气候变化因素

气候变化因子 (CCF) 是一种技术性防洪预防工具，于 2000 年代初在德国南部推出。CCF 被设计为附加费值，将添加到所有新技术防洪设施中，例如大坝、防护墙和保留区。本文解构了导致创建这一新政策工具的条件和过程。遵循工具选择框架，本文以启发式方式分析了从 1990 年代初到 2004 年引入工具时作为该过程一部分的机构、参与者、话语和决策背景。为了更好地理解该区域文书的范围，本文还简要描述了洪水风险和保护管理的四个非代表性案例，应用或避免使用该工具的地方。文章最后对 CCF 进行了评估，得出的结论是，一旦总体部门范式从技术性防洪保护转变为更全面的洪水风险管理，该工具的创新性就会消退。
