Sheet of A4 Paper

About This Data One sheet of A4 office paper embeds about 10 liters (roughly 2.6 gallons) of water, mostly for growing and pulping wood fiber. Source: Water Footprint Network. 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.
