The “Cement CO2 and Energy Protocol: CO2 and Energy Accounting and Reporting Standard for the Cement Industry” provides a harmonized methodology for calculating CO2 emissions, with a view to reporting these emissions transparently. It addresses all direct and the main indirect sources of CO2 emissions related to the cement manufacturing process, in absolute as well as in specific or unit-based terms.

The current version 3 was published in 2011 and is intended to be applied for reporting of CO2 data starting in the year 2012. It takes account of the further extended experiences with the application of the Protocol Version 2 and its evaluation for several years by many cement companies worldwide and in the CSI Getting the Numbers Right project (GNR). As reporting of energy (fuels, power) data is most important for the calculation of CO2 emissions, the name of the protocol has been amended to “Cement CO2 and Energy Protocol”.

This protocol is today the most relevant guidance document for the measurement and reporting of CO2 emissions in the cement industry worldwide. Most international cement firms use it, the EU Emissions Trading System, the US EPA Mandatory Reporting of Greenhouse Gases Rule, the California Climate Registry, and the Global Superior Energy Partnership (formerly Asia Pacific Partnership) have adopted it, and the European Standardization Organization (CEN) has accepted it as basis for developing a cement sector standard.

The protocol comprises three elements: A guidance document containing relevant definitions and explanations for the CO2 inventory, an Excel spreadsheet to help companies prepare their CO2 inventories, and the Internet Manual, which provides step-by-step guidance for filling out the protocol. It is designed to make it easy to find answers to questions on the practical aspects of CO2and energy reporting.
