Air Freshener Spray (300ml)

Material Composition Assumptions

A typical three-hundred-milliliter aerosol air freshener contains approximately forty-five grams of fragrance concentrate representing twelve percent of total weight. This concentrate consists of synthetic terpenes, aldehydes, and ester compounds that provide scent characteristics. The propellant system uses hydrocarbon gases like butane and propane or compressed nitrogen, comprising roughly sixty percent of the product mass at one hundred thirty-five grams.

Isopropyl alcohol or similar solvents make up approximately twenty grams or seven percent by weight. The aluminum or steel pressure vessel accounts for sixty grams representing twenty percent of total mass. A plastic actuator mechanism weighs roughly five grams, constituting the remaining one percent of product weight.

Manufacturing Geography

Primary manufacturing occurs in China where established aerosol filling facilities and fragrance blending operations concentrate production. The Chinese electrical grid operates at five hundred fifty-five grams of carbon dioxide per kilowatt-hour, significantly impacting energy-intensive processes like aluminum canister fabrication and chemical synthesis operations.

This geographic concentration results from proximity to raw material suppliers, established supply chains for metal packaging, and cost-competitive fragrance manufacturing capabilities. Transportation to global markets represents a meaningful portion of total lifecycle emissions due to the product’s relatively low value-to-weight ratio.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	52	Baseline
European Union	275 gCO2/kWh	47	-10% cleaner grid
United States	405 gCO2/kWh	50	-4% moderate reduction
India	650 gCO2/kWh	55	+6% higher emissions
Southeast Asia	485 gCO2/kWh	51	-2% slight improvement

Provenance Override Guidance

1. Manufacturing facility electrical grid carbon intensity data with monthly consumption records to refine energy-related emissions calculations.

2. Detailed material composition including specific fragrance chemical percentages, propellant type selection, and packaging material specifications with supplier documentation.

3. Transportation logistics data covering shipping methods, distances, and packaging density from production facility to distribution centers.

4. Packaging supplier lifecycle assessment data for aluminum canisters including recycled content percentages and manufacturing process efficiency metrics.

5. End-of-life management protocols including recycling rates, disposal methods, and regional waste treatment carbon intensities for accurate disposal impact calculations.

Methodology Notes

• The CCI score represents cradle-to-gate emissions through manufacturing completion but excludes consumer use phase and final disposal impacts.

• Scope three dominance reflects packaging manufacturing intensity and complex fragrance production chemistry requiring significant upstream processing.

• Functional unit assumes standard three-hundred-milliliter retail packaging representing typical household purchase quantities.

• Propellant release emissions during use phase fall outside current methodology boundaries despite contributing to atmospheric impacts.

• Regional regulatory variations affecting formulation chemistry create uncertainty in comparative assessments across different market jurisdictions.

• Secondary pollutant formation from indoor chemical reactions represents excluded impact category despite environmental relevance.
