Nylon Windbreaker / Rain Jacket

Material Composition Assumptions

This assessment assumes a standard nylon windbreaker weighing 400 grams total. The material breakdown includes 300 grams of nylon fabric comprising 75% of the total weight, with polyester lining accounting for 60 grams at 15% of total weight. Metal zippers contribute 25 grams representing 6% of the garment weight, while miscellaneous accessories including labels, elastic cuffs, and drawstrings make up the remaining 15 grams at 4% of total weight.

The nylon fabric component represents the dominant material by mass and the primary carbon emission driver. Consumer-grade windbreakers typically blend nylon 6 or nylon 6.6 fibers with varying weights ranging from lightweight performance models at 300 grams to heavier-duty versions reaching 500 grams.

Manufacturing Geography

Manufacturing occurs predominantly in China, which produces approximately 70% of global nylon textiles, along with secondary production in Vietnam and Bangladesh. The assessment uses China’s electrical grid intensity of 582 grams of carbon dioxide equivalent per kilowatt-hour based on 2023 data. This carbon-intensive electricity supply significantly impacts the total emissions profile since fabric manufacturing requires substantial energy inputs for heating, weaving, and finishing processes.

The concentration of nylon production in regions with coal-dependent electrical grids creates inherently higher carbon footprints compared to equivalent production in countries with cleaner energy sources. Manufacturing location represents one of the most significant variables affecting the final carbon intensity of nylon garments.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
EU	295 gCO2e/kWh	6	-25%
USA	386 gCO2e/kWh	7	-12%
India	708 gCO2e/kWh	9	+12%
Vietnam	695 gCO2e/kWh	9	+12%
Bangladesh	632 gCO2e/kWh	8	+2%

Provenance Override Guidance

1. Submit certified life cycle assessment data documenting the specific carbon footprint of nylon fiber production including nitrous oxide emissions quantification from adipic acid manufacturing processes.

2. Provide verified electricity consumption records and renewable energy certificates for all fabric manufacturing operations including weaving, dyeing, and finishing stages.

3. Document the geographical origin of raw materials with transportation distances and modes between nylon production facilities, fabric mills, and final assembly locations.

4. Supply detailed material composition data showing exact percentages of nylon, polyester, and accessory components along with their respective carbon intensities.

5. Present end-of-life disposal or recycling data demonstrating actual waste management pathways rather than theoretical disposal scenarios.

Methodology Notes

• The CCI score represents cradle-to-gate embodied carbon including raw material extraction, fiber production, fabric manufacturing, and garment assembly but excludes consumer use phase and disposal.

• Scope 1 emissions capture direct manufacturing processes including chemical reactions during nylon polymerization and nitrous oxide releases from adipic acid production.

• Scope 2 emissions account for electricity consumption during energy-intensive fabric production stages including heating, mechanical processing, and dyeing operations.

• Scope 3 emissions include upstream transportation of raw materials and intermediate products between manufacturing stages.

• The functional unit represents one complete windbreaker garment weighing 400 grams, suitable for comparison across similar lightweight outerwear products.

• Notable exclusions include packaging materials, retail distribution, consumer washing and maintenance, and end-of-life disposal or recycling processes.

• Data gaps exist for specific nitrous oxide emission factors from different nylon production technologies and regional variations in manufacturing process efficiency.
