Kayak Paddle (aluminum)

Material Composition Assumptions

The typical aluminum kayak paddle weighs approximately 650 grams and consists of several key components. The aluminum shaft represents the largest portion at roughly 350 grams or 55% of total weight, manufactured from high-strength alloys such as 6061-T6 or 7075-T6. The composite blade sections contribute approximately 200 grams or 30% of the paddle weight, typically constructed from fiberglass or plastic-reinforced materials. The grip section adds another 75 grams or 12% through plastic or fiberglass construction designed for ergonomic handling. Epoxy resin adhesives used to bond components together account for roughly 15 grams or 2% of the total weight. An anodized coating applied to the aluminum shaft for corrosion resistance represents less than 1% of the weight but provides essential durability protection.

Manufacturing Geography

Aluminum kayak paddle production primarily occurs in China, where the majority of global aluminum processing and recreational equipment manufacturing takes place. The Chinese electricity grid operates at an intensity of 555 gCO2e per kilowatt-hour, reflecting the country’s continued reliance on coal-fired power generation for industrial processes. This manufacturing location choice stems from established aluminum smelting infrastructure, lower labor costs, and proximity to supply chains for composite blade materials. The energy-intensive nature of aluminum processing makes grid carbon intensity a critical factor in determining overall product emissions, as both primary metal production and subsequent fabrication steps require substantial electrical input.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	5.0	Baseline
North America	330 gCO2e/kWh	3.5	-30% reduction
Canada (hydro regions)	120 gCO2e/kWh	2.0	-60% reduction

India	650 gCO2e/kWh	5.5	+10% increase

Provenance Override Guidance

1. Submit aluminum sourcing documentation specifying the percentage of recycled content versus primary aluminum, along with smelter location and energy sources used in production facilities.

2. Provide manufacturing facility energy audit data showing actual electricity consumption for extrusion, forming, and anodizing processes, including any renewable energy certificates or on-site generation.

3. Document transportation logistics including shipping distances, modal splits between ocean freight and trucking, and packaging specifications that affect shipping efficiency.

4. Supply material specifications for blade and grip components including specific polymer types, fiber content percentages, and manufacturing processes used for composite construction.

5. Provide end-of-life management data including recyclability rates for aluminum components and disposal or recovery processes for composite blade materials.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a complete aluminum kayak paddle including materials extraction, processing, manufacturing, and delivery to retail distribution.
• Scope 1 emissions encompass direct manufacturing activities including extrusion, forming, anodizing, and assembly operations at the paddle production facility.
• Scope 2 emissions account for purchased electricity consumption during manufacturing processes, with values reflecting the carbon intensity of regional electricity grids.
• Scope 3 upstream emissions dominate the footprint due to energy-intensive primary aluminum smelting and electrolysis processes required for raw material production.
• The functional unit assumes a single complete paddle suitable for recreational kayaking with standard durability expectations for aluminum construction.
• End-of-life impacts are excluded from this assessment, though aluminum’s high recyclability provides potential for closed-loop material recovery.
• Transportation emissions reflect typical shipping distances from Asian manufacturing centers to North American and European markets.
• Significant uncertainty exists around recycled content assumptions, as actual percentages vary widely between manufacturers and supply chains.
