Material Composition Assumptions
Standard ceramic floor tiles consist of several primary raw materials that form the base composition. Clay minerals including kaolin and illite typically comprise 45-50% of the total weight, providing plasticity and structural integrity during forming processes. Feldspar varieties such as potash and sodium feldspar constitute approximately 25-30% of the mixture, serving as fluxing agents that reduce firing temperatures. Quartz in the form of silica sand represents 20-25% of the composition, contributing strength and thermal stability to the finished product.
Additional components include specialized glaze materials that create the surface finish and decorative properties, accounting for roughly 5-8% of total weight. Water serves as the processing medium during mixing and shaping stages but evaporates during manufacturing. The typical weight assumption for this analysis considers tiles averaging 15-16 kilograms per square meter based on standard residential thickness specifications.
Manufacturing Geography
China dominates global ceramic tile production, accounting for approximately 65% of worldwide output through large-scale manufacturing facilities concentrated in Guangdong, Jiangxi, and Shandong provinces. The country’s extensive clay deposits, established supply chains, and manufacturing infrastructure create significant cost advantages for producers. Chinese facilities typically operate with grid electricity having an intensity of 555 gCO2/kWh, reflecting the substantial coal-fired power generation in industrial regions.
This manufacturing concentration results from decades of investment in specialized kiln technology, automated production lines, and integrated raw material processing capabilities. The scale of operations allows Chinese manufacturers to achieve economies that support both domestic consumption and global export markets across multiple continents.

Provenance Override Guidance
-
Submit detailed energy consumption data showing actual kWh usage per square meter during firing, drying, and machinery operations with supporting utility bills or metering records.
-
Provide comprehensive fuel mix documentation specifying the percentage split between natural gas, electricity, and any alternative energy sources used in production processes.
-
Supply transportation distance records for major raw materials including clay, feldspar, and quartz sources with corresponding shipping methods and fuel consumption data.
-
Document local electricity grid composition or renewable energy procurement agreements that differ from regional grid averages used in default calculations.
-
Submit kiln efficiency certifications, energy management system reports, or third-party energy audits demonstrating performance variations from industry standard assumptions.
Methodology Notes
- The CCI score represents cradle-to-gate emissions covering raw material extraction through finished tile production ready for installation.
- Scope 1 emissions reflect direct combustion of natural gas in kilns and drying equipment along with process-related emissions from clay decomposition.
- Scope 2 accounts for purchased electricity consumption in grinding, pressing, glazing, and material handling equipment.
- Scope 3 encompasses upstream impacts from raw material extraction, transportation to manufacturing sites, and auxiliary material production.
- Installation materials such as adhesives, grout, and underlayment are excluded from the functional unit boundary.
- End-of-life disposal or recycling impacts are not included in this cradle-to-gate assessment.
- Data limitations exist for smaller regional producers and specialty tile formulations that may deviate from standard composition assumptions.
