IBM ranks high for its reported emissions reductions of 40% from 1990 to 2005 against a 1990 base year, and is now working on the second stage goal of 12% by 2012 with a 2005 base year. IBM should set a longer term goal, and having made significant efficiency gains already, it should also set a target for a percentage of renewable energy to ensure that the current growth rate (18% in past year) continues.
IBM scores highly for its comprehensive plan to reduce its emissions, which has produced impressive gains in efficiency. The company has avoided the use of offsets, understanding that offsets actually undermine its ability to contribute to the reduction emissions of its clients. More attention is needed to expand the base of renewable energy percentage to well above the current 11%.
IBM scores highest in this new category for its transparency and approach to managing its data center footprint with increasing amounts of renewable electricity. Additional priority given to renewable energy access in its siting policy and discrimination against dirty energy sources would earn IBM full marks.
Supply Chain Footprint
IBM scores high for requiring Tier 1 suppliers to report their emissions and set voluntary reduction goals. Publication of more data and the savings results of this request would earn IBM full points.
