As a first step, each company's Energy Productivity is calculated for 2012, with Energy Productivity defined as Revenue ($US) / Total Energy Consumption (GJ). Each company's Energy Productivity is then percent-ranked against that of all Industry Group peers in the CKC research universe and multiplied by 0.75. The Global Industry Classification Standard (GICS) definition of "Industry Group" will be used. In the second step, the change in each company's Energy Productivity from 2010-2012 is calculated and percent-ranked against that of all same-Industry Group peers within the CKC research universe. If the company's percent-ranked 2012 Energy Productivity is top quartile, their percent-ranked change in Energy Productivity for 2010-2012 is multiplied by 1 and then by 0.25. If the company's percent-ranked 2012 Energy Productivity is second quartile, their percent-ranked change in Energy Productivity for 2010-2012 is multiplied by 0.75 and then by 0.25. If the company's percent-ranked 2012 Energy Productivity is third quartile, their percent-ranked change in Energy Productivity for 2010-2012 is multiplied by 0.5 and then by 0.25. If the company's percent-ranked 2012 Energy Productivity is bottom quartile, their percent-ranked change in Energy Productivity for 2010-2012 is multiplied by 0.25 and then by 0.25. In the third step, the values from the first and second steps are totaled.
