The Role and Institutional Impacts of Carbon Dioxide Removal Technologies in Climate Governance

As the global climate crisis intensifies, and with the establishment of the 1.5℃ temperature control target by the Paris Agreement, relying only on emission reduction makes it difficult to reach the net zero target. Therefore, Carbon Dioxide Removal (CDR) is accelerating towards early commercialization and becoming a key strategy for global climate governance in climate governance discourse has changed significantly. From the "Supplementary Options" in the IPCC Fifth Assessment Report to the "scientifically necessary path" for the 1.5°C temperature control target, CDR has now been elevated to the third pillar of global governance alongside "emission reduction and adaptation". This paper adopts the document analysis method and comparative analysis. The study found that CDR has completed the institutional transformation from "supplement" to "dependence" in climate governance discourse, but this transformation may produce a "moral hazard" effect - that is, excessive commitment to immature technologies may weaken the motivation for current emission reduction.
