55-inch LED TV

Material Composition Assumptions

The Climate Cost Index model for 55-inch LED televisions assumes a total weight of 21.5 kilograms distributed across five primary component categories. The LCD display panel represents the largest single component at 8,600 grams, comprising 40 percent of total product weight. This panel contains the liquid crystal matrix, backlight assembly, and optical films necessary for image generation.

Plastic housing and chassis components account for 5,375 grams or 25 percent of the television mass. These structural elements provide mounting points for internal components and create the external appearance of the device. Electronic components including circuit boards, processors, and power supplies contribute 4,300 grams representing 20 percent of total weight.

Metal frame and support structures add 2,150 grams at 10 percent of device weight, providing structural rigidity for the large screen format. The remaining 1,075 grams consist of glass elements and miscellaneous materials comprising 5 percent of total mass.

Manufacturing Geography

The default manufacturing region encompasses China, Taiwan, and South Korea, reflecting the concentration of display panel fabrication facilities and final assembly operations in East Asia. This geographic distribution leverages established semiconductor manufacturing infrastructure and specialized component supply chains.

The electricity grid intensity of 537 gCO2e per kilowatt-hour represents the weighted average for primary production facilities in this region. This grid intensity directly affects manufacturing emissions for energy-intensive processes including LCD panel production, plastic molding, and final assembly operations.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	537 gCO2e/kWh	185	baseline
Europe	296 gCO2e/kWh	157	-15%
India	743 gCO2e/kWh	213	+15%
South Korea	467 gCO2e/kWh	175	-5%
North America	378 gCO2e/kWh	168	-9%

Provenance Override Guidance

1. Submit product-specific lifecycle assessment documentation covering cradle-to-gate manufacturing emissions with third-party verification from recognized certification bodies.

2. Provide detailed bill of materials specifying exact weights and material types for all major components including display panel, housing, electronics, and structural elements.

3. Document actual manufacturing facility locations with corresponding grid electricity emission factors and renewable energy procurement agreements where applicable.

4. Supply energy consumption measurements for manufacturing processes including panel fabrication, plastic injection molding, electronic assembly, and quality testing operations.

5. Furnish transportation data covering component shipping from suppliers to final assembly facilities and distribution to regional markets including mode and distance information.

Methodology Notes

• The CCI score of 185 represents cradle-to-gate manufacturing emissions excluding use phase electricity consumption and end-of-life disposal processes.

• Scope 1 emissions at 92.5 kgCO2e capture direct combustion from manufacturing facilities while Scope 2 at 74.0 kgCO2e reflects purchased electricity for production processes.

• The functional unit covers one complete 55-inch LED television ready for retail distribution with standard accessories and packaging materials.

• Emissions from consumer usage patterns and electricity consumption during the operational lifetime are excluded from this manufacturing-focused assessment.

• Data gaps exist for certain specialized electronic components and regional variations in manufacturing process efficiency across different production facilities.
