Study Claims Spam Is Hurting The Environment

Can spam cause damage to the environment and contribute to greenhouse gas emissions? That's what a study from McAfee and climate-change researchers ICF have concluded. The study "Carbon Footprint of Spam" released today, found the global annual energy used to transmit, process and filter spam totals 33 billion kilowatt-hours (kWh), or 33 terawatt hours (TWh). That's equal to the electricity used in 2.4 million homes, with the same green-house gas as 3.1 million passenger cars using 2 billion gallons of gas.
