The information technology and the environment ICT

ICT also pollute, contribute 2% to the greenhouse effect. A French agency has conducted a study on the environmental impact of email, search and use USB. And Mc Afee commissioned a study on the pollution equivalent of SPAM.
Email: In 2014 it sent 507 billion messages, according to the report Arobase. In France, an employee of a company with a hundred workers receive an average of 58 messages and sent 33. An average of one mega mail applied to each employee produces 136 kilos of CO2 per year. The estimate includes everything from energy use by computers and databases that manage the traffic of shipping and receiving. “Reduce by 10% mailings in a company of 100 employees saves a ton of CO2 a year.” Printing messages are also contaminated, reducing by 10%, would save five tonnes of CO2 a year.

Searches: With an average of 949 Internet users search the Internet for a year, the study estimates that servers emit the equivalent of 9.9 kilos of CO2. Use of the favorites or the use of keywords would save five kilos per year.

USB: The effect of reading a 200-page document transferred by a USB 512 megs to be the time to read every page 3 minutes. If one hundred people attending a conference completely read the document -related emissions account for the transmission equivalent to 80 kg of CO2.

Spam: It turns out that there is a massive environmental impact of it. McAfee commissioned an environmental study and in 2009 the energy consumed in transmission and delete spam was equivalent to the electricity used by 2.4 million U.S. homes, or the equivalent CO2 emissions to 3.1 million cars. I know the 2011 data.
