About This Data
One roll of toilet paper embeds roughly 140 liters (about 37 gallons), mostly for pulp production. Consistent with the WFN paper figure of about 2,000 liters per kilogram. Source: Water Footprint Network (Mekonnen & Hoekstra), per-item estimate.
Figures are global-average totals (green + blue + grey water) per item and are not California-specific; the crop fact sheets on this site show California consumptive water use (green + blue, excludes grey) per serving, so compare with that difference in mind.
