Q. How often in the last 6 months were you able to fix something instead of throwing it away?
Endpoints:
Never - 0 kg
Always (fixed 5 times or more) - (9.73 x 5 times) / (6 months) = 8.11 kg CO2
Midpoints:
Fixed once or twice - (8.11) x (1/3) = 2.70 kg CO2
Fixed 3-4 times - (8.11) x (2/3) = 5.41 kg CO2
