Toilet Paper Roll

Material Composition Assumptions

A standard toilet paper roll weighing approximately 120 grams consists of several key components. The primary material is pulp fiber, representing 85% of the total weight at 102 grams, which can derive from virgin softwood and hardwood sources, recycled post-consumer paper, or alternative materials like bamboo. Water consumption during manufacturing exceeds 140 liters per roll, though this does not contribute to final product weight.

The cardboard core accounts for 8% of the weight at roughly 10 grams, typically manufactured from recycled paperboard. Packaging materials including plastic wrap made from polyethylene film comprise 4% at 5 grams. Chemical processing agents including bleaching compounds, wet-strength resins, and adhesives represent the remaining 3% at approximately 3 grams.

Virgin wood pulp products typically blend 30% softwood fibers for strength with 70% hardwood fibers for softness and absorbency. Alternative fiber sources like bamboo pulp offer similar performance characteristics while requiring different processing parameters and water usage patterns.

Manufacturing Geography

Toilet paper manufacturing occurs primarily across three major regions with distinct environmental profiles. Nordic countries including Finland and Sweden dominate high-quality tissue production, leveraging abundant renewable hydroelectric and biomass energy sources that result in grid intensities as low as 150-200 kgCO2e/MWh.

North American facilities concentrated in Canada and the southeastern United States utilize mixed energy grids averaging 400-500 kgCO2e/MWh while accessing abundant virgin fiber resources from managed forests. Latin American production, particularly in Brazil and Chile, focuses on fast-growing eucalyptus plantations with grid intensities ranging from 300-450 kgCO2e/MWh depending on hydroelectric availability.

Manufacturing location significantly influences carbon footprint due to varying electricity grid compositions, transportation distances to markets, and local fiber sourcing options. Nordic facilities achieve the lowest emissions through renewable energy integration, while regions dependent on coal or natural gas for electricity generation show substantially higher carbon intensities.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
Nordic (Finland/Sweden)	200 kgCO2e/MWh	0.14 kg CO2eq	-26%
North America (Canada/US)	450 kgCO2e/MWh	0.22 kg CO2eq	+16%
Latin America (Brazil)	350 kgCO2e/MWh	0.18 kg CO2eq	-5%
Europe (Mixed Grid)	300 kgCO2e/MWh	0.17 kg CO2eq	-11%
Asia Pacific (Coal Heavy)	650 kgCO2e/MWh	0.26 kg CO2eq	+37%

Provenance Override Guidance

1. Electricity consumption data with facility-specific renewable energy certificates or power purchase agreements demonstrating actual grid intensity below regional averages.

2. Fiber sourcing documentation including certified sustainable forestry practices, recycled content percentages, or alternative fiber sources like bamboo with associated land use change assessments.

3. Transportation logistics showing actual shipping distances and modal splits between rail, truck, and maritime transport from manufacturing facility to distribution centers.

4. Water treatment and chemical processing specifications detailing bleaching processes, de-inking procedures for recycled content, and wet-strength additive usage rates.

5. Packaging optimization measures including core material composition, plastic film thickness reduction, and end-of-life recyclability improvements beyond standard industry practices.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for one standard toilet paper roll excluding end-of-life disposal impacts and consumer use phase.

• Scope 3 emissions dominate the carbon footprint primarily due to upstream fiber production and processing, followed by Scope 2 electricity consumption during manufacturing.

• Functional unit assumes a typical household toilet paper roll weighing 120 grams with standard absorbency and strength characteristics.

• The assessment excludes potential carbon sequestration benefits from sustainable forest management practices and end-of-life biodegradability advantages.

• Data gaps include regional variations in forest management practices, detailed chemical processing energy requirements, and packaging material sourcing emissions.

• Deforestation impacts from virgin fiber sourcing represent significant unaccounted emissions particularly for products sourcing from old-growth or carbon-rich forest areas.
