27-inch Monitor

Material Composition Assumptions

The CCI score assumes a typical 27-inch monitor weighing 11 kilograms with the following material breakdown:

• Metals including aluminum, steel, and copper constitute 5,170 grams representing 47% of total device weight
• Plastic components for housing and internal structures account for 2,750 grams or 25% of total weight
• Glass components primarily for the LCD panel contribute 2,200 grams representing 20% of device mass
• Electronic components including printed circuit boards and integrated circuits total 660 grams or 6% of weight
• Other miscellaneous materials comprise the remaining 220 grams representing 2% of total device weight

The LCD panel structure includes silicon dioxide at 24.6% composition, aluminum oxide at 5.1%, calcium oxide at 2.7%, and organic carbon compounds at 65.1%. Monitor stands and frame assemblies add 2-4 kilograms of additional weight through aluminum or steel construction materials.

Manufacturing Geography

Primary manufacturing occurs across three major Asian electronics production centers: China, South Korea, and Taiwan. These regions dominate global LCD monitor production due to established semiconductor fabrication infrastructure and display panel manufacturing capabilities.

The default grid intensity assumption of 565 gCO2e per kilowatt-hour reflects China’s electricity generation profile, which heavily influences manufacturing emissions given the concentration of electronics production facilities in Chinese industrial zones. This grid intensity factor significantly affects Scope 2 emissions calculations for energy-intensive processes like LCD panel fabrication and final assembly operations.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
European Union	275 gCO2e/kWh	142	-13%
United States	385 gCO2e/kWh	152	-7%
South Korea	480 gCO2e/kWh	158	-4%
India	695 gCO2e/kWh	178	+9%
Australia	610 gCO2e/kWh	171	+4%

Provenance Override Guidance

1. LCD panel manufacturing data including energy consumption per square meter of active display area and process-specific emissions factors for thin-film transistor production
2. Primary materials extraction documentation covering aluminum smelting, steel production, and rare earth element mining with regional energy intensity factors
3. Electronics assembly facility data including surface-mount technology processes, component insertion operations, and quality testing energy requirements
4. Transportation logistics covering shipping distances, modal split between ocean freight and air cargo, and packaging material specifications
5. Final assembly location data with facility-specific electricity consumption patterns and local grid emission factors for accurate Scope 2 calculations

Methodology Notes

• The CCI score represents cradle-to-gate emissions covering raw material extraction through completed device manufacturing but excluding consumer use phase and end-of-life disposal
• Manufacturing activities dominate the emissions profile with approximately 80-85% of total lifecycle impacts occurring before product shipment, while operational use contributes only 15-20% over typical device lifespan
• Functional unit calculations assume one complete 27-inch LCD monitor including integrated stand, power supply, and standard accessories but excluding external cables or mounting hardware
• The assessment excludes downstream impacts from electricity consumption during consumer use, software installation, and device recycling or disposal processes
• Data gaps include regional variations in component sourcing patterns and facility-specific energy efficiency improvements that may reduce manufacturing emissions below baseline assumptions
