Pharmboy writes "A new report put out by Greenpeace argues that the IT sector is not doing enough to decrease reliance on 'dirty energy', saying the Internet, if it were treated as its own country, would be the 5th largest emitter of greenhouse gases. 'Many companies, the organization said, tightly guard data about the environmental impact and energy consumption of their IT operations. They also focus more on using energy efficiently than on sourcing it cleanly.' The report (PDF) doesn't mention how much CO2 is saved by telecommuting and higher corporate efficiency, however. So, exactly how 'green' or 'polluting' is the internet, really?"
