The Calculation of Product Carbon Footprint and Optimization Design

Abstract

With more and more governments and organizations taking Carbon Footprint as the measure of greenhouse gas emission, the study about the calculation of carbon footprint has become a hot spot. The paper analyzed the carbon footprint in different stages of a product life circle, including manufacturing, transporting, using and disposing and also studied the part contributing the largest carbon emission. Especially in the calculation of carbon emission of manufacturing stage, recursive call algorithm was applied. The optimization design model of carbon footprint was also depicted. All the work this paper had undertaken facilitates to formulate specific carbon emission reduction measures.

Integrated optimization of process planning and scheduling for reducing carbon emissions

“…Carbon emissions in a manufacturing system mainly include that caused by energy consumptions of machines and handling equipment, consumptions of coolant, wears of cutting tools and material swarfs etc. [28]. Process planning would determine cutting parameters and processing times of processes, and potential moving distances of workpieces between processes and scheduling would determine idling times of machines, and actual moving distances of workpieces between machines.…”
