Paper Towel Roll

A paper towel roll represents a single-use absorbent paper product designed for household cleaning and drying tasks. The manufacturing process involves energy-intensive pulping, bleaching, and paper formation operations that create substantial upstream environmental impacts. Each individual sheet generates carbon emissions while the full product lifecycle encompasses significant water consumption and forestry resource depletion.

Material Composition Assumptions

The baseline composition reflects a standard multi-ply household paper towel roll weighing approximately 600 grams:

• Virgin wood pulp (softwood or hardwood fibers): 480g (80%)
• Recycled paper (mixed office paper or brown packaging): 72g (12%)
• Bleach and chemical processing agents: 18g (3%)
• Water-based adhesive for ply bonding: 12g (2%)
• Cardboard tube core: 15g (2.5%)
• Plastic film wrapping (LDPE): 3g (0.5%)

Manufacturing Geography

North American facilities dominate global paper towel production due to abundant forestry resources and established pulp mill infrastructure. The regional electricity grid intensity of 0.386 kgCO2e/kWh reflects a mixed energy portfolio combining natural gas, renewable sources, and remaining coal generation. Manufacturing concentration in this region stems from proximity to softwood forests, existing papermaking expertise, and large domestic consumer markets that minimize transportation distances.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
North America	0.386 kgCO2e/kWh	52	Baseline
Northern Europe	0.295 kgCO2e/kWh	47	-10%
China	0.555 kgCO2e/kWh	58	+12%
Brazil	0.098 kgCO2e/kWh	44	-15%
Southeast Asia	0.492 kgCO2e/kWh	56	+8%

Provenance Override Guidance

Suppliers can provide the following data types to replace the default carbon assessment:

1. Verified electricity consumption data (kWh per ton of finished product) with specific grid emission factors for manufacturing facilities
2. Detailed fiber sourcing documentation including percentages of virgin versus recycled content with transportation distances
3. Chemical consumption records for bleaching agents and processing additives with supplier-specific emission factors
4. Steam and thermal energy usage data with fuel type specifications for pulping and drying operations
5. End-of-life waste management contracts specifying disposal methods and methane capture systems

Methodology Notes

• The CCI score represents cradle-to-grave emissions for one complete paper towel roll including manufacturing, distribution, use phase, and disposal
• Scope 3 dominance reflects upstream forestry impacts and downstream waste management emissions beyond direct manufacturing control
• Functional unit assumes standard household roll containing approximately 100 individual sheets with typical absorbency characteristics
• Assessment excludes consumer transportation from retail locations and storage-related emissions in household settings
• Data gaps include regional variations in forestry management practices and emerging chemical-free bleaching technologies
• Recycling potential remains limited due to contamination issues and shortened fiber lengths that prevent reprocessing
