AI Technical Summary
Existing carbon emission accounting methods for power equipment fail to fully reflect the carbon emission characteristics at each stage of the entire life cycle, especially ignoring the hidden carbon emissions during the manufacturing stage, and are difficult to reflect the coupling relationship and emission fluctuations between stages, resulting in unrefined analysis results.
A life-cycle-based carbon footprint analysis method and system for power equipment is constructed. By dividing the entire life cycle into stages, a mathematical model is established that includes life cycle stage weights, energy corrections, and system boundary corrections. Taking into account the coupling of multiple energy sources, a carbon footprint calculation model is constructed, and the carbon emissions of in-plant transfer vehicles and parts handling processes are introduced, taking into account stage coupling and fluctuation effects.
It enables a systematic and refined analysis of carbon emissions throughout the entire life cycle of power equipment, improves the completeness and accuracy of carbon footprint analysis in the manufacturing stage, and reflects the correlation effects and emission dispersion between different stages.
