Implementation of sub-sctoral MRV System in the Cement Industry in Ethiopia
Cement accounts for over half of the GHG emissions in Ethiopia’s industrial process and product use (IPPU) sector. While Ethiopia’s IPPU sector accounts for approximately 1% of total national emissions, cement production and the associated GHG emissions, have been increasing steadily since the late-1990s, with Ethiopia recording one of the world’s highest economic growth rates.
Given available Federal Ministry of Industry information and industry estimates, it is believed that the 2015 Second National Communication significantly underestimated the emissions of the cement sub-sector. With this background cement industry was selected as the sector receiving in-depth support in the implementation of an MRV system.
As a first step the institutional set-up and channels for data flow where mapped. The flow diagram shows the enhanced institutional set-up between government ministries and institutions within the cement sector, in terms of their roles and responsibilities regarding MRV, the reporting hierarchy and any mechanisms for communication and co-ordination among the institutions.
The GHG emissions from the cement sector occur in the stage of clinker production as a result of chemical reactions.These emissions are reported under IPPU. In addition, there are GHG emission associated with the fossil fuel combustion in the kilns – these emissions are typically reported under Energy. Therefore, the key parameters to be monitored are:
- Amount of clinker produced (or as a proxy percentage of clinker in the total cement production by cement type);
- Calcination of the clinker – the chemical properties of the raw materials used to produce clinker and the chemical reactions occurring in the process;
- Type and amount of fossil fuels used – in Ethiopia’s case, this is primarily Residual fuel oil;
- Net Calorific Value (NCV) of the fuel
The templates designed and presented in this website allow for estimation of GHG emissions based IPCC 2006 tier 1 and tier 2 methods.
