Televisions (LED/LCD)

Material Composition Assumptions

The default reference product is a 50-inch LED-backlit LCD television weighing approximately 13 kg (without stand), composed of:

• LCD panel module: Thin-film transistor (TFT) LCD panel with LED edge-lighting or direct backlighting, approximately 5-6 kg. Includes glass substrates, polarizer films, color filter array, and liquid crystal layer. Panel production involves clean-room photolithography processes with high energy intensity.
• Printed circuit boards (PCBs): Main board, power supply board, T-con board — approximately 0.5-1.0 kg. Contains integrated circuits, capacitors, resistors, and connectors assembled via surface-mount technology (SMT) with lead-free solder.
• Metal chassis and housing: Steel rear panel and aluminum frame, approximately 3-4 kg.
• Plastic housing: ABS or polycarbonate bezel and rear cover, approximately 1.5-2 kg.
• Power supply: Internal switched-mode power supply, approximately 0.5 kg.
• Cables, stand, and accessories: HDMI cables, remote control, stand bracket — approximately 1-2 kg.
• Packaging: Corrugated cardboard box, EPS foam corners, polyethylene bags — approximately 3-4 kg.

The LCD panel is the emission-dominant component. Panel manufacturing requires ultra-clean-room environments (Class 100-1000) with extreme energy inputs for photolithography, etching, deposition, and alignment processes across 5-8 mask layers.

Manufacturing Geography

Television manufacturing is concentrated in a small number of countries:

• LCD panel production: Dominated by China (BOE, CSOT), South Korea (Samsung Display, LG Display), Taiwan (AU Optronics, Innolux), and Japan (Sharp/Foxconn). Panel fabs are among the most energy-intensive manufacturing facilities in the electronics sector.
• Final assembly: Primarily China and Mexico (for North American markets). Some assembly in Poland and Turkey for European markets.
• Grid intensity (China): 565 gCO2e/kWh (IEA 2024). Used as the conservative default since China dominates both panel production and final assembly.
• Grid intensity (South Korea): 430 gCO2e/kWh (IEA 2024). Major panel fab locations include Asan and Paju.
• Rationale: LCD panel fabrication is extremely energy-intensive due to clean-room HVAC, vacuum deposition systems, and photolithography equipment. A single Gen 10.5 panel fab can consume 300-500 MW of continuous electricity.

Regional Variation

Panel + Assembly Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China (default)	~565 gCO2e/kWh	350 kgCO2e	Baseline
South Korea	~430 gCO2e/kWh	315 kgCO2e	-10%
Taiwan	~510 gCO2e/kWh	336 kgCO2e	-4%
Japan	~460 gCO2e/kWh	323 kgCO2e	-8%
Mexico (assembly only)	~410 gCO2e/kWh	310 kgCO2e	-11%

Note: Scope 2 represents 27% of total emissions. Panel manufacturing location is the primary driver of regional variation. Final assembly location matters less because assembly is less energy-intensive than panel fabrication.

Provenance Override Guidance

A supplier or brand may override the default CCI score by submitting:

1. Environmental Product Declaration (EPD) or Product Carbon Footprint (PCF) per ISO 14067 or IEC 63366 covering panel production through finished TV.
2. Panel supplier data: Specific panel fab energy consumption and grid intensity data. Samsung, LG, and BOE publish sustainability reports with facility-level energy data.
3. Factory energy data: Renewable energy procurement (PPAs, RECs/GOs) at panel fab and assembly facilities.
4. Component-level data: IC manufacturer product carbon footprints (increasingly published by Intel, TSMC, Samsung Foundry).
5. OLED vs. LCD: OLED panels eliminate the backlight unit but have higher panel-fabrication energy due to organic deposition processes. Net effect on total emissions is roughly similar for current-generation technology.

Methodology Notes

• CCI score of 350 kgCO2e represents a conservative estimate for a 50-inch LED LCD TV. Song et al. (2019) report 250-400 kgCO2e for 43-55 inch models. Prakash et al. (2016) report 300-400 kgCO2e. The CCI score reflects conservative assumptions about Chinese panel manufacturing with coal-intensive grids.
• Scope breakdown: Scope 3 dominates at 71% (250 kgCO2e), driven by LCD panel component manufacturing, semiconductor IC production, and upstream material extraction. Scope 2 is 27% (95 kgCO2e) from final assembly, testing, and factory electricity. Scope 1 is 2% (5 kgCO2e) from on-site process gases and thermal energy.
• Functional unit: One 50-inch LED LCD TV (~13 kg without stand), cradle to gate through packaged product.
• Use-phase emissions are excluded but significant. A 50-inch TV consuming ~80W for 5 hours/day over 7 years contributes approximately 300-500 kgCO2e in use-phase emissions depending on local grid intensity — comparable to production emissions.
• Size scaling: Emissions scale approximately with panel area. A 65-inch TV has roughly 70% more panel area than a 50-inch model, and production emissions typically scale to approximately 500-600 kgCO2e.
• Data gaps: Rapid technology shifts (Mini-LED backlight, OLED, QD-OLED) change the emission profile. Default score represents conventional LED-backlit LCD, still the dominant technology by volume.
