Last week, IBM announced that it would reduce its greenhouse gas emissions by 7% from 2005 levels by the year 2012. The commitment was made as part of the company’s participation in the Environmental Protection Agency’s ‘Climate Leaders’ program. To date, the ‘Climate Leaders’ program has enlisted more than 100 companies to set similar voluntary reduction targets. IBM’s most recent goal follows an earlier pledge in which the company successfully reduced its emissions by 6.2% from 2002 levels in 2005. The technology giant plans to achieve further reductions through improved energy efficiency in its offices and limited use of perfluorocompounds in semiconductor manufacturing. My, how times have changed since the IBM 5120 (pictured above) was introduced. See also ::A Personal Computer for the Planet
