Better Get Daylighting 

Each time you do this action you will save 0.9kg of CO2 

Calculation Method

By removing net curtains, cleaning your windows and generally brightening up the place Green Thing thinks that you won't need so many lights on in a room during the day so:

• Half the bulbs in a room will be turned off from 9-5 so: 8hrs
• 4.4 ¹ /2 = 2.2 (1/2 no of bulbs in a room)
• 0.0527kg ² x 2.2 = 0.12kg
• 0.12kg x 8hrs = 0.9kg
