The objective of this study is to reveal the importance of CO2emission reduction in the cement industry for the countries with strong demand. As a case study we worked on the opportunities of reducing CO2emissions in the cement industry in Turkey. By improving the technology, the average specific energy and specific electric consumption showed a decrease of nearly 4% and 5%, respectively over the last ten years. Process based CO2emissions followed a slight decrease due to changes in the utilised fuel and raw material blend from 0.50 ton CO2/ton cement in 2001 to 0.45 ton CO2/ton cement in 2015. Reduction in CO2emissions can be achieved mainly by effective waste heat recovery (WHR) systems and the increasing use of alternative fuel. When the percentage of alternative fuel usage reaches to 30.5% from the value of 2.38% 1.4 million tonnes of CO2eq reduction will be achieved.
