HOW TO USE
1) Enter amounts
2) Check factors
3) Press SOLVE
4) Total is kg CO2e
METHOD
impact = amount × factor
total = impact1+2+3
Units must match factor
EXAMPLE
car: 50×0.28 = 14.0
elec: 100×0.20 = 20.0
gas: 200×0.18 = 36.0
NOTES
Simple factors vary in real life
Use for rough comparison only
NO SCROLL is enforced
