Wi-Fi Router

Material Composition Assumptions

Wi-Fi routers contain several key components that drive their environmental impact profile. Integrated circuits and radio frequency integrated circuits represent the highest-impact materials, typically comprising 85-120 grams or roughly 15-20% of device weight. These semiconductor components require energy-intensive fabrication processes involving rare earth elements and specialized manufacturing facilities.

Printed wiring boards form the structural foundation, containing copper traces and substrate materials totaling approximately 65-85 grams or 12-15% of total weight. The chassis housing combines aluminum, steel, and ABS plastic components weighing 180-220 grams, representing the largest mass fraction at 35-40% of device weight.

Power supply components including transformers and capacitors contribute 45-65 grams or 8-12% of weight, while antenna and RF transmission components add another 25-35 grams. Memory chips and processing units round out the composition at 30-45 grams, typically accounting for 6-8% of total device mass.

Manufacturing Geography

China serves as the dominant manufacturing hub for Wi-Fi routers, hosting major production facilities for both contract manufacturers and original equipment producers. The region benefits from established semiconductor supply chains, skilled electronics assembly workforce, and proximity to component suppliers, making it the logical choice for cost-effective router production.

China’s grid intensity of 555 gCO2/kWh significantly influences the manufacturing carbon footprint, as router assembly requires substantial electricity for semiconductor fabrication, printed circuit board production, and final device testing. The coal-heavy electricity mix in major manufacturing provinces elevates the embodied carbon compared to production in regions with cleaner energy sources.

Costa Rica	99 gCO2/kWh	41	-37%

Provenance Override Guidance

1. Primary manufacturing facility location with specific grid intensity data and percentage of production volume allocated to that facility.

2. Detailed bill of materials specifying semiconductor sourcing, including wafer fabrication locations and packaging facility carbon intensities for major integrated circuits.

3. Transportation logistics data covering shipping methods, distances, and carrier efficiency metrics from component suppliers through final distribution.

4. Product-specific power consumption measurements under standardized testing conditions, including standby power, active transmission power, and thermal management requirements.

5. End-of-life processing arrangements demonstrating material recovery rates, recycling facility efficiency, and documented disposal pathways for non-recoverable components.

Methodology Notes

• The CCI score represents a typical consumer-grade wireless router with dual-band capabilities and standard feature set, excluding enterprise-grade equipment with higher power requirements.
• Scope 2 emissions dominate due to continuous operational electricity consumption, while Scope 3 manufacturing impacts concentrate in semiconductor production and printed wiring board fabrication.
• The functional unit covers one complete device ready for retail sale, including packaging materials and standard accessories like power adapters.
• Transport emissions beyond initial distribution and packaging materials other than primary product housing are excluded from this baseline assessment.
• Limited data availability for emerging manufacturing regions and next-generation semiconductor processes represents the primary uncertainty in current scoring methodology.
