As one of the original Climate Savers companies, IBM committed to achieve annual average reductions in greenhouse gas (GHG) emissions from 1998 to 2004. IBM met its initial commitment, which generated savings of $115 million.
“Energy conservation is a major component of IBM’s climate protection program because the release of CO2 by utility companies that power our facilities represents the greatest potential climate impact from our operations.” - 2006 IBM Corporate Responsibility Report
IBM extended its initial Climate Savers target to reduce CO2 emissions associated with its total energy use to 12% by 2012, and in the first year of the new commitment period, they reduced emissions by 2.8%.
In 2007, IBM announced that they would consolidate 3900 distributed servers onto 30 new generation mainframes, using 80% less energy and space in the process.
IBM has one of the largest corporate work-at-home programmes in the U.S. involving over 25,000 employees in 2005. This contributed to reductions of 5 million square feet (18%) in its US office space from 2000 to 2005 with significant energy savings, and conserved 5 million gallons of fuel, avoiding 50,000 tons of carbon dioxide emissions in 2005.
