Electrical Cable (per meter)

Material Composition Assumptions

The baseline electrical cable assessment considers a standard power distribution cable with the following material composition per meter:

• Copper or aluminum conductor: 300-400g (representing the primary conductive element and 60-85% of production emissions)
• Polyvinyl chloride or polyethylene insulation: 80-120g (providing electrical isolation and weather protection)
• Polymer jacketing material: 40-60g (offering mechanical protection and durability)
• Optional aluminum foil or mesh shielding: 20-30g (electromagnetic interference protection where required)
• Optional steel wire armoring: 100-150g (mechanical protection for underground or harsh environment installations)

The total weight per meter typically ranges from 500-800g depending on conductor size and protection requirements.

Manufacturing Geography

China dominates global electrical cable manufacturing, accounting for over 40% of worldwide production capacity. The country’s extensive copper processing infrastructure, large-scale polymer production facilities, and integrated supply chains make it the primary source for both domestic and export markets. Manufacturing occurs predominantly in industrial zones along the eastern coastal provinces, where grid intensity averages 555 gCO2e/kWh. This carbon-intensive electricity mix, heavily reliant on coal-fired power generation, significantly influences the embedded carbon content of Chinese-manufactured cables through energy-intensive metal processing and polymer production stages.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	52	Baseline
Germany	366 gCO2e/kWh	46	-12%
South Korea	436 gCO2e/kWh	49	-6%
Norway	17 gCO2e/kWh	28	-46%
India	708 gCO2e/kWh	58	+12%

Provenance Override Guidance

Suppliers can submit the following data types to override the default CCI score:

1. Conductor material origin documentation specifying recycled content percentage and primary aluminum smelting energy source
2. Manufacturing facility electricity consumption data with renewable energy certificates or power purchase agreements
3. Third-party lifecycle assessment reports covering raw material extraction through factory gate
4. Material composition specifications including insulation type, conductor alloy, and shielding materials
5. Transportation mode and distance data for major material inputs from extraction to manufacturing facility

Methodology Notes

• The CCI score represents cradle-to-gate emissions per meter of standard electrical cable, excluding use phase and end-of-life treatment
• Scope 3 dominates at 90% due to upstream raw material extraction and processing, particularly energy-intensive copper mining and aluminum smelting
• Functional unit covers one meter of cable suitable for standard electrical distribution applications
• Assessment excludes installation accessories, conduits, and specialized connectors that vary significantly by application
• Data gaps exist for emerging bio-based insulation materials and advanced conductor alloys with limited commercial deployment
• Regional electricity grid variations during material processing create substantial carbon footprint differences between manufacturing locations
