null. THE ENVIRONMENTAL IMPERATIVE. Given the energy-intensive nature of the cement-manufacturing process, it is perhaps not surprising that a twentieth of the world's man-made CO 2 emissions can be traced to a single industry: cement. About half of these emissions are a necessary by-product of the chemical reaction essential in …

The cement sector is one of the fast growing economic sectors in Ethiopia. In 2010, it consumed 7 PJ of primary energy. We evaluate the potential for energy savings and CO 2 emission reductions. We start by benchmarking the energy performance of 8 operating plants in 2010, and 12 plants under construction.
