At Siemens, activities for climate protection address the entire value chain. The supply chain emits four to six times more greenhouse gases (GHG) than its own manufacturing operations. Obviously Siemens has less influence on the GHG emission of the supply chain than on its own activities. To integrate the supply chain in the climate protection activities Siemens supports its supplier to reduce energy consumption and GHG emissions by
implementing the Energy Efficiency Program for Suppliers (EEP4S).
(Siemens, 2011)

The aim of the EEP4S is to involve suppliers into Siemens’ sustainability strategy and help them to conserve energy. Optimization potentials in environmental and energy efficiency summarized in a comprehensive report encourage Siemens suppliers to contribute on a green supply chain.
