49 dominant technology for decarbonisation that is viable at present, all direct measures in the process along with the add-on CCUS technology option remain of importance. Hence, a multipronged approach for CO 2 reduction is essential as the cement industry is local nature with captive limestone mines. Individual plants need to take up detailed studies in collaboration with research and technology groups. Conclusion In 2015 UNFCCC Paris Agreement was a testament to global determination to limit increasing global temperature rise to only 1.5 0 C. To achieve this limit all sectors of the economy including the cement sector must decarbonise rapidly reducing, CO 2 emission nearly half by 2030 and to net zero by 2050. The cement sector requires substantial financial support, clear guidance, and a framework of supportive policies to change the transition to net zero. Decarbonisation pathways are less obvious for the hard-to-abate cement sector. The challenges are not only in adapting the appropriate technology but also in overcoming financial and management barriers. To reach net zero CO 2 emission cement plant needs multi-prong strategies like reducing the amount of clinker in cement by product variation reducing fossil fuel for energy used in the production adapting the best available technology to minimise energy consumption capturing and utilising CO 2 and storing. The cement industry should now focus seriously on how to go about adapting suitable CCUS technology for individual cement plants in the present scenario. The cement sector emitted 196 Mtpa of CO 2 in the year 2020, which may rise to 325 million tonnes per annum by 2030. Carbon capture costs vary widely across industries/sectors, and the policy incentives need to be appropriately implemented in a phased manner to capture CO 2 in the cement industry. Advanced CCUS technology and governmental support in financial investment will play significant roles in achieving a zero- carbon future. The cement sector is at a critical stage in the transition to net zero.
