The Paris Agreement’s goal of limiting global warming to well below 2 °C, ideally 1.5 °C, places significant emphasis on Carbon Dioxide Removal (CDR) technologies. However, the global landscape for CDR deployment remains uneven, with significant disparities in technological capacity, economic readiness, and regional ambition. This study investigates how limited access to CDR technologies could exacerbate global economic inequality under a 1.5 °C pathway. Using the Global Change Analysis Model (GCAM v6.0), six scenarios ranging from unrestricted CDR availability to constrained deployment are evaluated.
