CO₂ and energy performance data is collected on:

• Specific gross and net CO₂ emissions per ton clinker, cement and cementitious product
• Absolute gross and net CO₂ emissions
• Thermal energy consumption per ton clinker
• Electric energy consumption per ton cement
• Fuel mix (fossil fuel / fossil waste / biomass)
• Clinker to cement ratios

To enable calculation of the percentiles, trend lines and correlations, company facilities were also required to provide:

• Clinker and cement production volumes
• Differentiation by grey and white clinker
• Type of installation
• Location of installation
• Nominal capacity
• Year of construction
