Car Air Freshener

Material Composition Assumptions

The typical car air freshener contains approximately 20-25 grams of fragrance oils representing the primary active ingredient. The polypropylene housing weighs roughly 8-12 grams and provides the structural framework for the product. Polyethylene terephthalate membranes account for 2-3 grams and control the release rate of volatile compounds. Hexylene glycol carrier fluid comprises 3-5 grams and serves as a solvent medium. Metal springs contribute 1-2 grams for mechanical attachment mechanisms. Cotton or woven board substrates add 3-4 grams as absorption media. Foil lining materials represent 1-2 grams for barrier protection. Plastic blister packaging typically weighs 5-8 grams for retail presentation and protection during distribution.

Manufacturing Geography

China serves as the dominant manufacturing hub for car air fresheners due to established chemical processing infrastructure and proximity to fragrance oil suppliers. The electricity grid intensity of 555 grams of carbon dioxide equivalent per kilowatt-hour reflects the coal-heavy energy mix typical of industrial regions. Manufacturing concentrates in coastal provinces where petrochemical facilities provide raw materials for both fragrance synthesis and plastic component production. Transportation costs favor Asian production centers given the lightweight nature of finished products and established logistics networks for automotive accessory distribution.

Provenance Override Guidance

1. Submit detailed bills of materials showing recycled content percentages for polypropylene housing and polyethylene terephthalate components with third-party verification certificates.

2. Provide facility-specific electricity consumption data including renewable energy procurement agreements and on-site generation capacity documentation.

3. Document fragrance oil sourcing with supply chain mapping showing petrochemical feedstock origins and processing energy intensity measurements.

4. Submit packaging design specifications demonstrating mono-material construction or recyclability improvements with end-of-life pathway verification.

5. Provide transportation logistics data including shipping distances, modal split between air and ocean freight, and last-mile delivery carbon footprint calculations.

Methodology Notes

• The CCI score represents cradle-to-gate carbon emissions for a single disposable car air freshener unit including all materials, manufacturing energy, and packaging components.

• Scope 3 emissions dominate the profile due to packaging production and disposal representing nearly two-thirds of total environmental impact across product lifecycles.

• The functional unit assumes a standard hanging-style air freshener with approximately 40 grams total weight and 30-day active fragrance duration.

• End-of-life disposal emissions are excluded from the current methodology despite significant environmental impacts from non-recyclable multi-layer packaging materials.

• Data gaps exist for fragrance formulation specifics and volatile organic compound emission factors during the use phase of the product lifecycle.

• Regional regulatory compliance costs for extended producer responsibility programs are not reflected in carbon accounting but affect overall sustainability economics.
