Greenhouse gases (GHG) emissions analysis of manufacturing of the hydraulic press slider within forging machine in China

Product manufacturing stage is one of the main contributors for greenhouse gases (GHG) emissions in China. The study aims to find the potential to control GHG emissions during forging machine's manufacturing stage in China for substantially reducing energy consumption and GHG emissions. Taking hydraulic press slider, a typical part of forging machines, as the research object, a complete GHG emission calculation method is proposed for its manufacturing stage, and the key factors affecting the GHG emissions are analyzed in order to provide support for the low carbon design and manufacturing of forging machines. The results show that the use of raw material of steel sheet is the largest contributor to GHG emissions in the manufacturing stage of forging machines, followed by welding. Some possible solutions to reduce the GHG emissions are also discussed.
