The Protocol for Accounting and Reporting of Avoided GHG Emissions through the Value Chain of Cement and Cement-based Products has been formulated to identify the contribution of cement products to avoided CO2 emissions. The Protocol covers the contribution of cement to avoided CO2 emissions in the whole life cycle from raw materials procurement and manufacturing in the production process to use in concrete or other products and disposal.
Manufactured cement, which is mainly used in concrete for structures and buildings, has the feature of uptaking and fixing CO2 in the atmosphere while the structures or buildings are in service or subsequent demolishing. The Protocol specifies how to calculate the CO2 absorption capacity by the cement produced in the whole life cycle. According to the calculation, the lifetime CO2 absorption capacity of the cement produced in 2017 is estimated to be about 2 million tons for the products of Taiheiyo Cement Corporation (inside Japan) or about 2.8 million tons for the products of the entire Taiheiyo Cement Group (inside and outside Japan), which constitutes no small contribution.
The formulation of the Protocol and the calculation of the CO2 absorption capacity of cement have been conducted through the exchange of ideas with external expertise from an environmental management consulting company and finalized after a third-party review by Lloyd's Register Quality Assurance Limited, an external certification body.
