ICT Carbon Footprint
- The global information and communications technology (ICT) industry accounts for approximately 2 percent of global carbon dioxide (CO2) emissions, a figure equivalent to aviation" - Gartner 2007.
- 18% of office workers never switch off their PC at night or weekends, and a further 13% leave it on some nights each week, producing about 700,000 tons of CO2 emissions (equivalent to the annual emissions of a typical gas-fired power station) - World Economic Forum Green Technology 2009 Report
- With the fast growth of ICT application in business operation and people’s daily life, the total electricity consumption of ICT and other consumer electronics worldwide is predicted to double by 2022 compared to the level in 2010, while tripled by 2030 to 1,700 tera (trillion) watts – Gadgets and Gigawatts: Policies for Energy Efficient Electronics
- A photocopier which is left switched on overnight needs the same amount of energy as it does to make 1500 photocopies. [Experton 2007]
- The total footprint of the ICT sector – including personal computers (PCs) and peripherals, telecoms networks and devices and data centres – was estimated at 830 MtCO2e, about 2% of the estimated total emissions from human activity in 2007. Even if the efficient technology developments are implemented, this figure seems to grow at 6% each year until 2020. - SMART 2020 Report
- The cost of running data centre facilities is rising by as much as 20% a year, far outpacing overall IT spending, which is increasing at a rate of 6% (World Economic Forum Green Technology 2009 Report)
- A data centre with 1000 servers uses enough electricity in a single month to power 16,800 homes for a year. (Forrester Research)
- It was also estimated that ICT has the potential to reduce global emissions by 15% by 2020. (Smart 2020 Report)
Reuse ICT Equipments
- At least 240 kilograms of fossil fuels, 22 kilograms of chemicals and 1,500 kilograms of water are required to produce one desktop computer. - Computer Aid International
- Only 20 percent of total energy use goes into running a computer; the rest is in its manufacture. - Computer Aid International
