Dog Collar (nylon)

Material Composition Assumptions

A typical nylon dog collar weighs approximately 30 grams and consists primarily of woven nylon webbing material. The dominant component is synthetic polymer fiber, comprising roughly 85% of the total weight at 25.5 grams. Additional components include plastic hardware elements such as buckles and adjustment mechanisms, accounting for 12% or 3.6 grams. The remaining 3% consists of metal components like D-rings for leash attachment, along with potential chemical treatments including dyes and protective finishes applied during manufacturing.

Manufacturing Geography

Primary manufacturing occurs in China, where the majority of global nylon production facilities operate alongside pet accessory assembly operations. The Chinese electrical grid operates at an intensity of 555 gCO2/kWh according to IEA data, reflecting the country’s continued reliance on coal-fired power generation. This manufacturing concentration results from established petrochemical infrastructure, integrated supply chains linking polymer production to finished goods assembly, and cost advantages in both energy-intensive nylon synthesis and labor-intensive finishing processes.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	52	Baseline
United States	386 gCO2/kWh	47	-10%
European Union	275 gCO2/kWh	42	-19%
India	708 gCO2/kWh	57	+10%
Brazil	85 gCO2/kWh	35	-33%

Provenance Override Guidance

1. Supplier-specific electricity procurement documentation showing renewable energy certificates or power purchase agreements for manufacturing facilities.

2. Material composition specifications detailing the percentage of recycled nylon content versus virgin polymer feedstock.

3. Manufacturing process energy consumption data measured in megajoules per kilogram of finished product output.

4. Transportation mode and distance documentation from polymer production sites to collar assembly facilities.

5. Third-party verified lifecycle assessment reports covering the complete supply chain from adipic acid synthesis through finished product packaging.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a single nylon dog collar including raw material extraction, polymer synthesis, fiber production, and assembly processes.

• Scope 3 emissions dominate the carbon footprint due to energy-intensive nylon polymerization processes and the release of nitrous oxide during adipic acid production.

• The functional unit assumes a standard adjustable collar weighing 30 grams with typical nylon webbing construction.

• Transportation from manufacturing facilities to retail points and consumer use phase impacts are excluded from this assessment.

• End-of-life disposal modeling reflects average waste management practices but excludes potential recycling scenarios that could reduce overall impact.

• Data gaps exist regarding specific chemical finishing processes and regional variations in polymer production efficiency.
