This study investigates the trends in greenhouse gas emissions across various sectors in India, focusing on carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). By estimating and evaluating the emissions and removals from key sectors, including industrial, agricultural, and other significant subsectors, this research aims to comprehensively analyse the types and sources of greenhouse gases emitted by India's industries. The study conducts a detailed trend analysis within multiple subsectors, identifying significant patterns and discrepancies over different time periods. A comparative analysis between the industrial and agricultural sectors highlights the differences in emission sources and levels. Furthermore, this research delves into the measures and initiatives undertaken by the Indian government to mitigate greenhouse gas emissions and promote sustainable development. This includes policies, regulations, and programs to reduce emissions and enhance environmental sustainability. The findings of this study are expected to contribute to a deeper understanding of sector-specific emissions in India, offering valuable insights into the effectiveness of current policies and suggesting areas for improvement. This research aims to inform and influence policy-making for enhanced environmental sustainability in India by comprehensively evaluating emissions trends and government actions.
