Kite (nylon/fiberglass)

Material Composition Assumptions

The carbon footprint assessment assumes a typical recreational kite weighing approximately 500 grams with the following material distribution:

• Fiberglass framework and reinforcement: 225 grams (45% of total weight)
• Nylon fabric covering for sail area: 125 grams (25% of total weight)
• Epoxy or polyester resin binder: 100 grams (20% of total weight)
• Wooden frame components or additional fiberglass elements: 35 grams (7% of total weight)
• Adhesives, coatings, and hardware: 15 grams (3% of total weight)

These proportions reflect standard construction methods for medium-sized recreational kites where structural integrity and wind resistance drive material selection decisions.

Manufacturing Geography

Primary manufacturing occurs in coastal Chinese provinces, particularly Shandong and Jiangsu, where established composite manufacturing infrastructure serves both domestic and export markets. The regional electricity grid operates at approximately 555 gCO2 per kilowatt-hour, reflecting the coal-dominated energy mix typical of industrial regions in eastern China. This location choice stems from proximity to petrochemical feedstock suppliers for resin production, established glass fiber manufacturing facilities, and textile production capabilities for nylon components.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China (East Coast)	555 gCO2/kWh	8.5	Baseline
Germany	366 gCO2/kWh	7.8	-8%
United States	386 gCO2/kWh	8.0	-6%
India	708 gCO2/kWh	9.4	+11%
Norway	17 gCO2/kWh	6.2	-27%

Provenance Override Guidance

1. Submit actual resin formulation data including specific polymer type, catalyst systems, and production facility location with associated energy consumption records.

2. Provide glass fiber specifications detailing furnace energy source, raw material composition ratios, and manufacturing process efficiency metrics from the specific production facility.

3. Document nylon fabric production parameters including polymerization method, spinning technology, and dyeing processes used for the specific textile components.

4. Supply transportation logistics data covering shipping distances, modal splits between ocean freight and trucking, and packaging material specifications.

5. Present end-of-life scenarios with regional waste management practices and any available recycling or recovery programs for composite materials.

Methodology Notes

• The CCI score represents cradle-to-grave emissions for a complete kite unit including manufacturing, transportation, and disposal phases
• Scope 3 emissions dominate the profile due to energy-intensive upstream material production, particularly resin synthesis and glass fiber melting processes
• Functional unit consists of one complete kite suitable for recreational flying with typical lifespan assumptions
• Manufacturing energy consumption excludes facility overhead heating and administrative operations
• Data gaps exist around specific adhesive formulations and regional variations in composite curing processes
• End-of-life modeling assumes landfill disposal due to limited recyclability of mixed fiber-resin composites
