Abstract: The present study identifies anthropogenic CO2 hotspots over the Indian region using columnar (XCO2) measurements from multiple satellites (AIRS, GOSAT, and OCO‐2/3) along with anthropogenic CO2 emissions from EDGAR, covering ∼23 years (2002–2024). The results indicate that India exhibited an annual CO2 trend of 2.31 ppm year−1, corresponding to a 17% increase in atmospheric CO2 during the study period. To further characterize anthropogenic CO2 sources, additional proxies of urban and industrial activities were analyzed: night‐time light (NTL) data for urbanization, NOx (NO + NO2) emissions for industrial activities, and atmospheric NO2 concentrations, as these species are co‐emitted during fossil‐fuel combustion. The combined analyses consistently identified major anthropogenic CO2 hotspots across India, with Sonbhadra and Vindhyachal emerging as the highest‐emitting coal mining and thermal power plant regions, respectively. The results also reveal that industrialization surpasses urbanization in contributing to enhanced emissions. To understand the climatic implications of CO2 emissions, ERA5 and IMD data sets were examined across Köppen climatic zones for the same period. The Tundra (ET) climatic zone is found to be rapidly warming and drying, whereas the Tropical Monsoon (Am) zone exhibits a favorable balance between dense vegetation and urbanization, resulting in minimal seasonal temperature variability. In contrast, the Indo‐Gangetic Plain (IGP) and National Capital Region (NCR) show significant increases in land surface temperatures during both day and night. Overall, the study highlights the need for region‐ and sector‐specific mitigation strategies for India, with particular attention to the IGP and NCR regions where warming trends are most pronounced. Plain Language Summary: Identifying anthropogenic CO2 hotspots and their environmental impacts are crucial for effective strategies to mitigate them. Thus, this study examines anthropogenic CO₂ hotspots over the Indian region using space‐borne and emission data of atmospheric CO2 and NO2 covering the period (2002–2024). The results indicate that CO₂ levels grew 2.31 ppm year⁻¹ over the Indian region, indicating a 17% increase in atmospheric CO2 during the study period. To determine the CO2 emission anthropogenic source type, proxies such as nighttime light data and NOx emissions were used in this study. This study identified anthropogenic CO2 hotspots with Sonbhadra and Vindhyachal as the highest emitting coal mining and thermal power plants in this study. Further, in this study, meteorology was investigated across Köppen climatic zones. The tundra climatic zone is warming and drying off swiftly, whereas the Tropical Monsoon zone is stable. Key Points: Examined anthropogenic CO2 hotspots with proxies such as Nighttime light data and oxides of NitrogenIdentified the crucial areas that require priority attention for region‐specific and sector‐specific policy developmentCO2 enhanced 17% in 2024 with a growth rate of 2.31 ppm year−1.
