Office equipment accounts for 15% of all energy used in business. Unchecked, this is expected to reach 30% by 2020. 5 minutes is all it takes to start reducing your company's environmental impact and saving money. You can start by switching off your computers, printers, and photocopiers at night and at the weekend. Turn off the lights that aren't necessary when you leave at the end of the day. And make sure you only print what you absolutely need too.
