Have you ever considered the environmental impact of drying your hands? How you can know, Use our Hand Drying Footprint Calculator to find out. Enter your hand-drying habits into the calculator to see your carbon footprint.
What is Hand Drying Footprint?
The Hand Drying Footprint measures the carbon emissions produced by different hand-drying methods. This includes the use of paper towels, warm air dryers, and jet air dryers.

Select the drying method and enter the values to calculate the carbon footprint
How to Use the Calculator
To use the calculator, input the following details:
- Drying Method: Choose between paper towels, warm air dryer, or jet air dryer.
- Sheets per Use: Enter the number of paper towel sheets used each time you dry your hands. For example,
2. - Energy per Use (kWh): Enter the energy consumed per use by the dryer. For example,
0.02. - Uses per Day: Enter how many times you dry your hands per day. For example,
50. - Days per Year: Enter the number of days you use hand drying in a year. For example,
365. - Carbon Intensity of Electricity (kg CO2e/kWh): Enter the carbon intensity of electricity. For example,
0.5. - Carbon Intensity of Paper Towels (kg CO2e/sheet): Enter the carbon footprint per sheet of paper towel. For example,
0.02.
Formula
The calculator uses the following formulas:
1. For Paper Towels:
Variables
| Variable | Description |
|---|---|
| Drying Method | Method used for drying hands (paper towels or air dryers) |
| Sheets per Use | Number of paper towel sheets used per drying |
| Energy per Use (kWh) | Energy consumed per use by the dryer |
| Uses per Day | Number of hand drying uses per day |
| Days per Year | Number of days hand drying is used in a year |
| Carbon Intensity of Electricity (kg CO2e/kWh) | CO2 emissions per kWh of electricity used |
| Carbon Intensity of Paper Towels (kg CO2e/sheet) | CO2 emissions per sheet of paper towel used |
