A First Approach to the Use of CO2 Emissions as a Maintenance Indicator in Industrial Plants

Maintenance operations are particular important in continuous systems and even more so when they apply to the part considered the system's bottleneck. Although complex support systems that help in decision-making decision therefore tend to be used, in industrial plants use of a simple indicator can facilitate management and help improve results. Concern for the environment and environmental legislation is meanwhile prompting a need to reduce CO2 emissions. Hence the proposal for the introduction of the CO2 emissions/Production ratio indicator. This paper will therefore both evaluate whether it is suitable as an indicator of system efficiency, with consideration for availability, stoppage time, average stoppage time and the duration of micro-stops, and also consider the ratio between monthly emissions and emissions on days with stops.
