The computation is based on the website https://c.environmentalpaper.org/
The total of sheets you saved is based on: the number of sent sign requests x number of sheets in the document x (number of contacts who need to sign + number of contacts in copy if the sign request is signed) = total of pages. We assume that one page weights 0.005 kilograms.
I've got a total weight, and now?
- Based on https://c.environmentalpaper.org/ we've got a list of consumption for 1000 kg of paper usage.
- We display to you a ratio based on the saved weight versus 1000 kg of paper usage.

For 1000kg of paper usage, with 10% of recycled paper, environmental savings are based on https://c.environmentalpaper.org/ and:
- Wood Use: 4 US Short Tons = 4*907.18474 = 3628.73 kg
- Total Energy: 27 Millions BTU = 27,000,000*0.0002931 = 7.91 kWh
- Gas: 18,700 Pounds of CO² = 18,700*0.4536 = 8482.32 kg
- Water: 23,400 Gallons = 23,400*3.78541 = 88578.59 L
- Solid Waste: 1290 Pounds = 1290*0.4536 = 585.14 kg
What about those conversions I see?
Based on various websites, here are our comparisons:
- A shower uses approximately 65 L of water
- To produce 1000 kg of wood, we have to cut 12 trees
- One liter of gas fuel will produce 8.9 kg of CO²
- One can weighs 15 g
- An average computer will consume 750 Wh
