Abstract: As critical hubs for long-distance transportation, railway passenger stations (RPSs) significantly influence energy conservation and CO 2 mitigation. This study investigates the spatiotemporal patterns and driving factors of CO 2 emissions across 247 Chinese RPSs (2014–2023), proposing region-specific decarbonization strategies. The key findings include: (1) Emissions increased universally during 2014–2023, with severe cold zones and developed cities hosting the most high-emission RPSs; (2) purchased thermal energy dominated the emissions in severe cold/cold zones, while purchased electricity prevailed in other zones; (3) the heating area (HA) was a primary emission driver, whereas the percentage of lighting energy consumption (PLEC) served as a key constraint, as shown by correlation and PCA analyses; (4) CO 2 emissions in severe cold zones exhibited strong correlations with heating-related factors, whereas emissions in other zones were predominantly linked to energy structure-related factors. These findings provide region-specific, actionable strategies to support CO 2 emission reduction planning for RPSs.
