Carbon sequestration in shale gas operations represents a crucial pathway to achieve Geological Negative Emissions, which is essential for global 1.5 °C targets. However, the emissions reduction potential and economic viability of this approach in China’s shale gas value chain remain unclear. This study quantifies the potential for transforming China’s shale gas value chain from an emission source to a carbon sink, while revealing spatial heterogeneity in economic feasibility.
