One use of paper towels (2 sheets, hand drying)
Paperipyyhkeiden käyttö (2 arkkia, käsien kuivaus)
Carbon and waste well-established from Gregory et al. (2013) MIT study. Water and land estimated from paper manufacturing data.
Two paper towel sheets produce ~15 g CO₂e and 5g of non-recyclable waste per hand-drying. Small per use, but hundreds of billions are used globally each year.
How was this number determined?
The Truecost score is calculated from absolute physical values. Each row below shows the measured value, how it was normalized, and where it comes from.
| Dimension | Absolute value | Score 100 = | Normalized | Weight | Weighted | Confidence |
|---|---|---|---|---|---|---|
| Carbon Emissions | 0.015 kg CO₂e | 9.5 kg CO₂e | 0.16 | ×0.35 | 0.06 | HIGH |
| Water Consumption | 0.1 liters | 3840 liters | 0.0 | ×0.2 | 0.00 | MEDIUM |
| Land Use | 0.001 m²·year | 51 m²·year | 0.0 | ×0.2 | 0.00 | LOW |

- Terrapass (2023): How to Reduce the Carbon Footprint of Your Paper Towels
Well-studied. Range: 10-26g depending on virgin vs recycled pulp. Most commercial restrooms use virgin paper.
- UD-TECH (2024): Water Consumption in the Pulp and Paper Industry
Small absolute number but adds up across billions of uses daily worldwide.
- FAO (2020): Global Forest Resources Assessment
Many paper towel brands now use recycled content, reducing virgin forestry demand.
- Gregory et al. (2013): Life-cycle assessment comparison of hand-drying options
Paper towels are not recyclable and generate significant solid waste at scale.
- Bajpai (2019): Pollutants released from the pulp paper industry
Negligible direct toxicity to user. Manufacturing emissions are the main concern.
Comparisons
- Carbon: 2 paper towels ≈ 2x the carbon footprint of a hand dryer
- Waste: 10 hand dryings per day = 18 kg of paper towel waste per year
Methodology
Based on Gregory et al. (2013) MIT lifecycle assessment of hand-drying options. Covers pulp production, paper manufacturing, transport, and disposal.
