Leaving your computer and monitor on during out of office hours can produce as much greenhouse pollution each year as driving your car from Melbourne to Perth.

Lights account for up to 60% of energy use in an office tenancy. Leaving lights on for a year in a small office* when they're not needed requires 37 mature trees to offset the greenhouse pollution generated.
*office size of 10 x 10 metres

Leaving a photocopier on standby during out of office hours can waste enough energy each year to burn a compact fluorescent light in your kitchen for more than 2.5 years.

The combined standby power from a whiteboard, microwave oven, hot water boiler and 20 mobile phone chargers can produce as much greenhouse pollution each year as driving your car 2,800 kilometres.
