Computers Emit As Much Carbon Dioxide As Aviation
By Mr Ethanol | June 13, 2007

Did you ever think how much do you contribute to the greenhouse gases emissions while using your personal computer?
How much did the global emissions increase with every computer manufactured?
Every single computer requires about 1.8 tonnes of chemicals, fossil fuels and water for its manufacture. And once in use, it emits about 0.1 tonne of carbon dioxide in a year.
According to a research, computers generate an estimated 35 million tonnes of carbon dioxide into the atmosphere each year. The emissions by pcs account for 2% of world’s total carbon dioxide emissions, almost equal to that contributed by aviation.

Every computer is good for some 3 years and then turns into junk. Though it’s a different story in less developed countries where a computer is used for a longer period and even those considered scrap in the developed nations are junked and used here. The junk computers are often dumped in landfills, polluting the soil with poisonous elements like cadmium and mercury.
The carbon emissions by computers is causing concerns that it may wreck attempts to reduce emissions. The dumping of old computers into developing countries is another concern. Dumping is just a way of transferring your burden to someone else. This will obviously have a negative affect on the health of the environment in the developing countries. The increasing penetration of computers is not only worsening the global warming but also polluting soil.
But with such heavy dependence on computers, a decrease in number of computers is quite unlikely. Imagine a world without computers. We will have to revert back to old days for this. Since the decrease in number of computers is not possible, efforts are being made to turn the computers green. Energy efficient computing along with access to Internet, mail and other common processes like word-processing without a CPU are being looked at as possible solutions.
A company in India has already ventured into providing computing to homes without having to have a computer. All one need is a monitor with keyboard and mouse and a connection with the service provider’s server. The server does the processing job, enabling computing without a CPU. (Sorry! I don’t remember the name of the company offering the service.)
In the increasing global warming scenario, we should obviously switch over to more energy efficient computing and also other gadgets like TV. Obviously, we don’t want to be responsible for worsening the climate change on the planet. And one last suggestion for the corporates - Please turnoff computers in your office when not in use. This will save lot of energy and thus saving the planet from significant amount of emissions.
