Wool Scarf

Material Composition Assumptions

A typical wool scarf contains approximately 150 grams of material composed entirely of sheep wool fiber processed from greasy fleece. The default assumption models 100% virgin wool content sourced from conventional sheep farming operations. Alternative compositions may include recycled post-consumer wool content, which substantially reduces upstream environmental impacts. The fiber undergoes standard textile processing including scouring, carding, spinning into yarn, and final knitting or weaving into scarf form.

Manufacturing Geography

Primary wool scarf production occurs in Australia and New Zealand, which together account for significant global wool fiber supply. These regions maintain established sheep farming operations and integrated textile processing infrastructure. The regional electricity grid intensity averages 620 gCO2/kWh, reflecting the coal-heavy energy mix typical of Australian manufacturing. This grid intensity directly affects energy-intensive processing stages including mechanical fiber preparation and thermal dyeing operations.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
Australia/New Zealand	620 gCO2/kWh	52	Baseline
United Kingdom	230 gCO2/kWh	46	-12%
China	710 gCO2/kWh	57	+10%
Uruguay	380 gCO2/kWh	49	-6%
Argentina	450 gCO2/kWh	50	-4%

Provenance Override Guidance

1. Farm-level emission factors for sheep operations including specific data on enteric methane production rates and manure management practices.

2. Wool processing facility energy consumption records with actual electricity usage data for scouring, carding, and spinning operations.

3. Transportation distance documentation covering fleece-to-mill and mill-to-market shipping with specific carrier and route information.

4. Recycled content verification showing percentage of post-consumer wool fiber incorporated in final product composition.

5. Dyeing and finishing process specifications including chemical inputs, water treatment systems, and thermal energy requirements.

Methodology Notes

• The CCI score represents cradle-to-grave emissions for a standard 150-gram wool scarf including expected consumer use patterns over typical product lifetime.

• Scope 3 dominates the emission profile due to upstream sheep farming impacts and downstream consumer care requirements throughout product use phase.

• The functional unit assumes 300 wear cycles over five years with standard home washing frequency and air-drying practices.

• Excluded impacts include retail infrastructure, packaging materials, and end-of-life disposal or recycling processing.

• Significant data gaps exist around regional variations in sheep breed efficiency and grazing system carbon sequestration potential.
