Gaming Mouse

Material Composition Assumptions

The CCI score for gaming mice assumes a typical unit weighing 100 grams with specific material distributions. The dominant component is the ABS plastic housing at 68 grams, representing 68% of total weight. The printed circuit board assembly contributes 18 grams or 18% of the total mass. Electronic components including optical sensors, microcontrollers, and surface-mount devices account for 10 grams at 10% of weight. Cable assemblies and connectors add 3 grams representing 3% of the product. Packaging materials contribute the remaining 1 gram at 1% of total weight.

The PCB assembly incorporates copper traces weighing 8-12 grams and FR-4 fiberglass substrate materials at 5-8 grams. Electronic components undergo intensive manufacturing requiring specialized fabrication facilities for integrated circuits and optical sensors.

Manufacturing Geography

Production concentrates in China’s Guangdong province and Shenzhen economic zones due to established electronics manufacturing clusters and supply chain infrastructure. These regions operate with grid electricity generating 565 gCO2e per kilowatt-hour based on coal-dominant power generation. Manufacturing processes demand significant energy inputs including injection molding operations consuming 1.2-1.8 megajoules per kilogram of ABS plastic, PCB fabrication requiring 15-25 kilowatt-hours per square meter, and final assembly operations using 0.3-0.5 kilowatt-hours per completed unit.

The concentration of component suppliers and assembly facilities in these manufacturing hubs enables integrated production while contributing to the carbon intensity through China’s electricity generation profile.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
Europe (Germany)	380 gCO2e/kWh	3.2	-20%
North America (US)	425 gCO2e/kWh	3.5	-12%
Southeast Asia (Malaysia)	620 gCO2e/kWh	4.3	+8%
India	708 gCO2e/kWh	4.7	+18%
Nordic (Norway)	45 gCO2e/kWh	2.1	-48%

Provenance Override Guidance

1. Factory-specific electricity consumption data measured in kilowatt-hours per unit produced, including breakdown by manufacturing process stage such as injection molding, PCB assembly, and final testing operations.

2. Detailed bill of materials specifying exact plastic grades, recycled content percentages, PCB substrate specifications, and electronic component supplier locations with associated transportation distances.

3. Primary manufacturing facility location with grid electricity carbon intensity documentation or renewable energy procurement agreements that modify the regional electricity emissions factor.

4. Injection molding process parameters including cycle times, energy consumption per shot, and material utilization rates that affect plastic processing efficiency and waste generation.

5. End-of-life material recovery data demonstrating actual recycling rates achieved for ABS plastics, copper recovery from PCBs, and electronic component reclamation percentages.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a standard 100-gram gaming mouse produced in Chinese manufacturing facilities with regional grid electricity.

• Scope 1 emissions dominate through direct fuel combustion in plastic processing and manufacturing operations, while Scope 2 electricity consumption reflects China’s carbon-intensive grid for assembly processes.

• Scope 3 upstream emissions capture electronic component production and raw material extraction typically occurring in specialized facilities separate from final assembly locations.

• The functional unit represents one complete gaming mouse ready for retail distribution, excluding user-phase electricity consumption and end-of-life processing impacts.

• Material composition excludes optional accessories, specialized packaging beyond standard retail boxes, and software development impacts associated with driver programming.

• Data limitations include variability in PCB complexity across different gaming mouse models and uncertainty in recycled content adoption rates among manufacturers.

• End-of-life recycling potential reaches 60-70% material recovery rates under optimal e-waste processing conditions, though actual recovery depends on regional waste management infrastructure.
