Tennis Racket

Tennis rackets represent a complex manufactured product with significant embodied carbon due to their advanced composite material construction. Modern rackets rely heavily on carbon fiber and graphite composites that require energy-intensive production processes, contributing to an average carbon footprint of 25 kg CO₂e per unit.

The environmental impact stems primarily from upstream material production rather than the manufacturing assembly process itself. Carbon fiber production accounts for the largest share of emissions, as this petroleum-derived material requires extreme heat and specialized chemical processing. The design phase proves critical, determining approximately four-fifths of the total environmental burden through material selection and structural engineering decisions.

Material Composition Assumptions

A typical tennis racket weighing approximately 300 grams consists of the following material breakdown:

• Carbon fiber comprises 210-240 grams representing 70-80% of the frame structure and providing the primary structural integrity
• Epoxy resin totals roughly 30-45 grams serving as the binding agent that holds composite layers together
• Polyurethane foam fills the handle core at approximately 15 grams for shock absorption and weight distribution
• Rubber or polyurethane grip material adds 10-15 grams for player comfort and control
• Polyester or nylon strings contribute 5-8 grams when installed for ball contact surface
• Aluminum or thermoplastic components including end caps and hardware total 8-12 grams
• Paint and coating systems add 2-5 grams through pigments, binders, and protective solvents

Manufacturing Geography

Tennis racket production concentrates heavily in China and Southeast Asia, where specialized composite manufacturing facilities have developed extensive expertise in carbon fiber processing. This regional concentration reflects both cost advantages and technical capabilities required for precision composite layup and curing processes.

Chinese manufacturing benefits from established supply chains for carbon fiber precursors and epoxy systems, though the coal-heavy electricity grid contributes significantly to manufacturing emissions. The national grid intensity of 555 gCO₂/kWh substantially exceeds global averages, particularly impacting the energy-intensive curing ovens and autoclave processes required for composite racket frames.

Alternative production regions like Taiwan and Thailand offer similar technical capabilities with moderately lower grid intensities, while maintaining proximity to key material suppliers and shipping infrastructure for global distribution.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO₂/kWh	25.0 kg CO₂e	Baseline
Taiwan	509 gCO₂/kWh	23.8 kg CO₂e	-4.8%
Germany	366 gCO₂/kWh	20.1 kg CO₂e	-19.6%
Japan	462 gCO₂/kWh	22.9 kg CO₂e	-8.4%
France	52 gCO₂/kWh	15.2 kg CO₂e	-39.2%

Provenance Override Guidance

Suppliers can submit the following data types to override the default CCI score:

1. Detailed material composition breakdown including specific carbon fiber grades, resin systems, and recycled content percentages with supporting documentation from material suppliers
2. Manufacturing facility energy consumption data including electricity usage per unit, fuel consumption for heating processes, and renewable energy certificates or power purchase agreements
3. Transportation and logistics documentation covering shipping distances, modes of transport, and packaging specifications from material suppliers through final distribution
4. End-of-life program documentation including take-back initiatives, recycling partnerships, or reuse programs that demonstrate measurable waste diversion from landfills
5. Third-party life cycle assessment reports conducted according to ISO 14040 standards that include cradle-to-gate or cradle-to-grave analysis specific to the product model

Methodology Notes

• The CCI score represents cradle-to-gate emissions including material extraction, processing, manufacturing, and transportation to retail distribution centers
• Scope 3 emissions dominate due to carbon-intensive upstream material production, particularly carbon fiber precursor manufacturing and high-temperature processing
• Functional unit assumes one complete racket ready for retail sale, excluding strings which are typically installed separately
• Manufacturing energy allocation reflects typical composite curing processes including autoclave or oven heating cycles required for proper resin polymerization
• Excluded elements include retail operations, consumer transportation, maintenance products, and replacement strings during product use phase
• Data gaps exist around end-of-life recycling rates due to limited infrastructure for composite material recovery and the technical challenges of separating carbon fiber from cured resin matrices
