IBM achieved strong sustainability results in energy conservation, data centre energy efficiency and environmental responsibility last year. The company saved more than US$43 million in electricity expenses and conserved 378,000 megawatt hours of electricity last year. IBM's energy conservation projects delivered savings equal to 7.4% of the company's total energy use, significantly exceeding the annual goal of 3.5%. This was the result of an ambitious ongoing program involving 2,300 conservation projects at more than 364 IBM facilities around the world.
IBM says it will continue these conservation efforts and aim to eliminate 1.1 million megawatt hours of energy consumption by the end of 2012. IBM's long-term sustainability policies are paying off. From 1990-2011, the company's energy conservation efforts have avoided 5.8 billion kWh of electricity consumption, nearly 3.8 million metric tons of CO2 emissions, and saved the company US$442 million.
