Projects implemented by Six Sigma teams focused on heating efficiency, more efficient lighting and control of equipment and can be replicated across the globe at Caterpillar facilities, not only reducing emissions, but also saving money, improving quality and engaging employees.
The results: In 2006, Caterpillar reduced its total global greenhouse gas (GHG) emissions by 36 percent per dollar of revenue, exceeding its 2010 goal of 20 percent intensity reduction. The company again exceeded the goal in 2007 with a 38 percent intensity reduction over 2002.
For Caterpillar to use Six Sigma teams to drive its sustainable projects is actually no surprise. Caterpillar has been a Six Sigma company for years now, and has been reaping benefits from it.
