General comment The values determined to calculate A1 (cement) and A3 originate from verified Lafarge inventory data. A1 values (raw
materials) were prepared considering specific EPDs (for cements), GCCA v3.2 data.
The allocation rules used for this EPD are based on general requirements provided in ITB PCR A and EN 15804+A2. As
no co-products are produced, the flow of materials and energy and the associated release of substances and energy into
the environment are related exclusively to the concrete mix produced. ECOPlanet cement from the offer of Lafarge
Cement S.A. is used. In the case of fly ash, eco-product from electricity production used as a cement constituent,
economic allocation was applied. Minimum 99.5% of impacts from the production lines were allocated to product covered
by this declaration. Emissions allocated in clinker/cement production (module A1) are assessed including international
methods for ETS system declaration. Calculations for GWP indicator are made taking into account gross and net
emissions. The indicated gross value includes the CO2 emissions from waste incineration (excluding biomass fraction of
fuels), net-value excluding impacts from alternative waste-based fuels.
In this assessment, all information gathered from data collection for the production of concrete has been modelled, i.e. all
raw materials used, the electrical energy and other fuels used, use of ancillary materials and all direct production waste.
Transport data on input was considered. No cut-offs have been made in accordance with EN 15804. The machines and
facilities (capital goods) required for and during production are excluded, as is transportation of employees. Calculations
for GWP indicator are made taking into account gross and net emissions.
