File Folder (cardboard)

Material Composition Assumptions

Cardboard file folders consist primarily of corrugated cardboard with an average recycled content of approximately sixty-one percent. The remaining material composition includes kraft paper layers that provide structural integrity, adhesives and glues for bonding components, printing inks and surface coatings for labeling and protection, and virgin wood pulp fibers when recycled content is insufficient. A typical file folder weighing fifty grams contains approximately thirty grams of recycled cardboard, twelve grams of kraft paper layers, five grams of virgin pulp content, two grams of adhesives, and one gram of inks and coatings.

Manufacturing Geography

Cardboard file folders are predominantly manufactured in the United States and China, where established papermaking infrastructure and proximity to both recycled material sources and end markets create cost efficiencies. The United States grid intensity of 389 gCO2/kWh significantly influences the carbon footprint of energy-intensive pulping and containerboard production processes. Chinese manufacturing facilities often rely on coal-heavy electricity grids with higher carbon intensities, though some mills have adopted biomass combustion systems that reduce overall emissions. Regional concentration in these markets reflects the availability of recycled cardboard feedstock and mature distribution networks for office supply products.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
United States	389 gCO2/kWh	52	Baseline
China	555 gCO2/kWh	58	+12% higher
Germany	338 gCO2/kWh	47	-10% lower
Sweden	45 gCO2/kWh	38	-27% lower
India	709 gCO2/kWh	64	+23% higher

Provenance Override Guidance

1. Mill energy source documentation showing renewable electricity usage, biomass combustion rates, and fossil fuel consumption data for containerboard production facilities.

2. Recycled content verification certificates indicating the actual percentage of post-consumer and post-industrial recycled fibers used in folder manufacturing.

3. Transportation distance records from containerboard mills to converting facilities and from converters to distribution centers or end customers.

4. End-of-life waste management contracts specifying recycling rates, landfill diversion percentages, and methane capture systems at disposal facilities.

5. Virgin fiber sourcing certifications demonstrating sustainable forestry practices, carbon sequestration credits, and forest management sustainability standards.

Methodology Notes

• The CCI score represents cradle-to-grave emissions for a standard fifty-gram cardboard file folder including raw material extraction, manufacturing, transportation, and end-of-life disposal.

• Scope 3 emissions dominate the footprint due to upstream containerboard production processes, raw material transportation, and downstream disposal impacts in the value chain.

• The functional unit assumes a single-use file folder with typical office storage applications over a one-year service life before disposal.

• Excluded impacts include office equipment for filing systems, paper documents stored within folders, and potential reuse scenarios that extend product lifespan.

• Data gaps exist for regional variations in recycling infrastructure efficiency and the carbon benefits of avoided virgin material production through recycled content usage.
