Linen Shirt

Material Composition Assumptions

The assessment assumes a standard linen shirt weighing approximately 180 grams composed entirely of flax-derived linen fiber. This natural cellulose fiber represents one hundred percent of the garment material composition. Flax plants undergo minimal chemical processing during cultivation, requiring primarily rainwater irrigation without synthetic pesticides. The fiber processing involves mechanical separation and spinning operations that transform raw flax into weaveable textile material.

Manufacturing Geography

Primary manufacturing occurs in China, where coal-fired electricity generation creates a grid intensity of 555 grams of carbon dioxide per kilowatt-hour. This region dominates global textile production due to established supply chains and manufacturing infrastructure. The coal-dependent electrical grid significantly amplifies emissions during energy-intensive processes including weaving, cutting, and garment assembly operations compared to regions utilizing cleaner energy sources.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	13.0	Baseline
France	85 gCO2/kWh	10.2	-22%
India	712 gCO2/kWh	14.8	+14%
Turkey	424 gCO2/kWh	12.1	-7%
Bangladesh	502 gCO2/kWh	12.6	-3%

Provenance Override Guidance

1. Electricity consumption data from manufacturing facility including energy sources and grid mix verification documentation.

2. Flax fiber sourcing records demonstrating cultivation location, farming practices, and transportation distances from field to processing facility.

3. Detailed manufacturing process specifications including water usage, chemical inputs during dyeing, and waste treatment methodologies.

4. Transportation documentation covering shipping methods, distances, and fuel consumption from manufacturing location to distribution centers.

5. End-of-life treatment protocols including garment disposal, recycling programs, or biodegradation pathways in target markets.

Methodology Notes

• The CCI score represents total lifecycle emissions including cultivation, manufacturing, distribution, consumer use, and disposal phases for one linen shirt unit.

• Scope 3 emissions dominate the assessment due to consumer washing and ironing activities throughout the garment’s useful life, representing approximately eighty percent of total impacts.

• The functional unit assumes normal consumer care patterns including weekly washing cycles and periodic ironing over a three-year garment lifespan.

• Packaging materials, retail infrastructure, and marketing activities are excluded from the current assessment boundary.

• Carbon sequestration benefits during flax cultivation are not credited against the total emissions score, representing a conservative assessment approach.

• Regional electricity grid variations during consumer use phase create substantial uncertainty in final emissions calculations depending on garment usage location.
