Cement, the most used commodity in the construction sector, contributed to around 30% of the total GHG emissions from the Indian industrial sector. The demand for cement is expected to grow in the coming years, due to the introduction of various schemes like the smart city mission, Housing for all, and launch of several infrastructure projects among others. Therefore, along with growing demand, comes the growing GHG emissions associated with the production of cement. To achieve the country’s climate change mitigation targets of reducing the GHG emission intensity of its GDP by 33%-35% taking 2005 as the base year and to restrict the global temperature change in the century by 2°C, there is an urgent need to reduce these emissions. Before going to the discussion on different ways of mitigating GHG emissions from the cement industry, it is crucial to understand the different processes involved in cement production and different sources of emissions from the cement industry. Cement is one of the most technologically advanced industries in our country. The modern Indian Cement plants are state-of-the-art plants and are comparable to the best in the world. The Indian Cement Industry has managed to keep pace with the global technological advancement. The induction of advanced technology has helped the industry immensely to improve its efficiency by conserving energy, and fuel for addressing environmental concerns. The capacity utilization of Indian Cement Industry during the last 10 years has fallen from 83% to 60%. Figure-3 depicts Indian cement Installed capacity, actual production, and capacity utilization. The continuous downward trend of capacity utilization is indicative of the idle capacity of over 200 million tonnes which is growing year by year. Figure 3 Depicts Indian cement Installed capacity, production and is capacity utilization The cement industry comprises about 150 integrated large cement plants, 116 grinding units, 62 mini cement plants and 5 clinkerization units.
