Today's ecological crises are entwined with inequality dynamics, yet prevailing techno-economic approaches in climate research and policy fall short in addressing the ecological crisis as distributional crisis. Recognising the limitations of techno-economism, focused on markets (price adjustments) and technology (efficiency gains), this contribution introduces sufficiency corridors as a concept, research field, and policy approach. Sufficiency corridors represent the space between a floor of meeting needs and a ceiling of ungeneralisable excess, i.e. within the sufficiency corridor everyone has enough (to satisfy needs) while no one has too much (to endanger planetary boundaries and need satisfaction). Establishing such corridors entails a process over time that continuously narrows the gap between floors and ceilings, lifting the former and pushing down the latter by strengthening forms of consumption and production that contribute to need satisfaction while shrinking those that do not. The article discusses the profound implications of this approach for how societal reality is reproduced and/or changed, highlighting the need for decisions that eliminate options between and within sectors and in the realms of consumption and production. After addressing questions of decision-making and the potential to realise corridors, the contribution concludes that the growing scientific consensus to complement techno-economic approaches with sufficiency measures remains inadequate. Instead, the possibility of a transformation by design hinges on embedding techno-economism within and subordinating it to a sufficiency framework.

当今的生态危机与不平等动态交织在一起，但气候研究和政策中流行的技术经济方法不足以将生态危机视为分配危机。认识到技术经济主义的局限性，重点关注市场（价格调整）和技术（效率增益），本文引入了充足走廊作为概念、研究领域和政策方法。充足性走廊代表了满足需求的最低限度和不可普遍的过剩的上限之间的空间，即在充足性走廊内，每个人都有足够的东西（满足需求），而没有人拥有太多（危及地球边界和需要满足）。建立这样的走廊需要一个过程，随着时间的推移，不断缩小地板和天花板之间的差距，通过加强有助于满足需求的消费和生产形式，同时缩小那些不能满足需求的消费和生产形式，提升前者并压低后者。本文讨论了这种方法对社会现实如何复制和/或改变的深远影响，强调需要做出消除部门之间和部门内部以及消费和生产领域的选择的决策。在解决了决策和实现走廊的潜力问题后，本文得出的结论是，以充足措施补充技术经济方法的日益增长的科学共识仍然不够。相反，设计转型的可能性取决于将技术经济主义嵌入并使其服从于充足性框架。
