Wooden Desk

Material Composition Assumptions

The typical wooden desk weighs approximately 24 kilograms and consists of several key material components. Solid wood or engineered wood panels comprise the largest portion at roughly 18 kilograms or 75 percent of total weight, forming the desktop surface and structural elements. Plywood or particleboard backing materials account for an additional 3 kilograms or 12.5 percent. Metal hardware including drawer slides, handles, and fastening screws contributes approximately 1.5 kilograms or 6 percent of the total weight. Surface coatings such as lacquer or UV-cured finishes represent about 1 kilogram or 4 percent, while adhesives and binding compounds used in lamination and assembly make up the remaining 0.5 kilograms or 2.5 percent of the desk’s composition.

Manufacturing Geography

Most wooden desk production occurs in China, which dominates global furniture manufacturing due to established supply chains, processing infrastructure, and labor cost advantages. Chinese furniture factories benefit from proximity to both domestic forestry resources and imported timber from Russia, Southeast Asia, and North America. The country’s electrical grid operates at an average carbon intensity of 555 grams of carbon dioxide equivalent per kilowatt hour, reflecting the continued reliance on coal-fired power generation mixed with growing renewable capacity. This grid intensity directly impacts the carbon footprint of energy-intensive manufacturing processes including sawmill operations, machining, and surface finishing treatments.

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	82 kg CO2e	Baseline
Germany	366 gCO2/kWh	75 kg CO2e	-8.5%
Canada	120 gCO2/kWh	68 kg CO2e	-17%
Poland	645 gCO2/kWh	87 kg CO2e	+6%
Brazil	75 gCO2/kWh	65 kg CO2e	-21%

Provenance Override Guidance

1. Submit verified lumber sourcing documentation including forest management certification status, species type, and transportation distance from harvest location to manufacturing facility.

2. Provide detailed energy consumption data from manufacturing operations with breakdown of electricity usage by process stage and renewable energy percentage in facility power supply.

3. Document actual material composition including precise weights of solid wood versus engineered wood products, adhesive types and quantities, and metal hardware specifications.

4. Supply transportation logistics data covering shipping methods, distances, and carrier efficiency for both raw material delivery and finished product distribution.

5. Include surface treatment specifications detailing coating types, application methods, volatile organic compound content, and curing energy requirements.

Methodology Notes

• The CCI score represents cradle-to-gate emissions covering raw material extraction through manufacturing completion but excludes use phase and end-of-life disposal impacts.

• Scope 3 emissions dominate the footprint due to upstream wood processing, forestry operations, and transportation requirements, while Scope 2 reflects energy-intensive milling and finishing processes.

• The functional unit assumes a standard office desk weighing 24 kilograms with mixed wood construction and typical hardware components.

• Biogenic carbon storage benefits are excluded from this assessment, though wood products can sequester atmospheric carbon that may offset manufacturing emissions over time.

• Data gaps exist around regional variations in forestry practices, adhesive formulations, and end-of-life scenarios that could significantly influence total lifecycle impacts.
