IBM has been tracking its energy consumption since 1973, and has had a number of energy conservation goals over the years and a
previous CO2 emissions reduction goal. IBM's current CO2 emissions reduction goal is its second generation goal. The goal:
- Between 1990 and 2005, IBM reduced or avoided CO2 emissions by an amount equivalent to 40 percent of its 1990 emissions through its global energy conservation program. To further extend this achievement, IBM set itself an aggressive "second generation" goal: to reduce the CO2 emissions associated with its energy use 12 percent by 2012 against a 2005 base year through
energy conservation and the procurement of renewable energy.
As of year-end 2011, the company's energy conservation results and procurement of renewable energy resulted in a 16 percent reduction in IBM's energy-related CO2
emissions from the 2005 base year of this goal. Operational CO2 emissions increased slightly from 2010 to 2011 primarily due to the decrease in renewable electricity purchases and associated 12.9 percent decrease in
avoided CO2 emissions.
IBM's CO2 emissions reductions have been achieved through the actions outlined below. In addition, improvements in the CO2 emissions profile of the electricity that IBM
purchased also had a favorable, albeit limited, impact on the company's performance.
- IBM's energy conservation efforts have reduced or avoided a total of 1.5 million MWh of electricity and 2.7 million MMBTU of fuel use (based on one-year savings
associated with conservation projects) from 2006 to 2011, which represents a reduction in IBM's electricity and fuel use of 2.6 percent and 23.2 percent, respectively,
against the 2005 baseline use adjusted for acquisitions and divestitures.
- IBM purchased 518,000 MWh of electricity generated from renewable sources in 2011, resulting in an avoidance of 215,000 metric tons of CO2 emissions associated with
the generation of the electricity used by IBM. We contract for these purchases through programs sponsored by suppliers or the responsible utility.
