The idea of a global “carbon budget”—the cumulative amount of “allowable” carbon emissions to meet a global temperature target—has become established as a central concept in climate science and policy. As a concept explicitly aimed at mediating between scientific knowledge and policymaking, the carbon budget has always been actively positioned in relation to ongoing policy debates, but the specific forms this concept has taken have varied. This article reviews key contributions to the carbon budget literature from the 1980s until today, in order to identify how scientists have positioned the concept between the worlds of science and policy. Three main shifts are identified in how the policy relevance of the carbon budget is envisaged in the scientific literature. The shifts can be related in part to developments in climate science, and in part to changes in international climate policy. The history of the carbon budget thus illustrates how science and policy interacts to shape dominant understandings of how climate change can be known and governed.

全球碳预算的历史

全球“碳预算”的概念（满足全球温度目标的“允许”碳排放量的累积量）已成为气候科学和政策的中心概念。作为明确旨在在科学知识和政策制定之间进行调解的概念，碳预算一直相对于正在进行的政策辩论始终处于积极位置，但是该概念采取的具体形式却有所不同。本文回顾了从1980年代到今天对碳预算文献的主要贡献，以确定科学家如何将这一概念置于科学与政策之间。在科学文献中如何设想碳预算的政策相关性方面，确定了三个主要转变。这些变化可能部分与气候科学的发展有关，部分是由于国际气候政策的变化。因此，碳预算的历史说明了科学与政策如何相互作用以形成对如何知道和治理气候变化的主要理解。
