Abstract

Concept of ‘carbon footprint’ is derived from ‘ecological footprint’, where the Life Cycle Assessment (LCA) method is used to evaluate the greenhouse gas emission directly or indirectly generated by the research object during its life cycle. Compared with the traditional carbon emission amounts, the calculation results based on the LCA method are more comprehensive and accurate, which is crucial for the reasonable evaluation of carbon emission situation and carbon asset management of enterprises. In this study, based on the carbon footprint evaluation theory, frequently used calculation methods, including measure method, material balance algorithm, emission coefficient method and asset estimation method, were investigated and summarized, and combined them into the life cycle assessment model effectively. Taking a substation as the research object, its carbon footprint was analyzed and estimated. The obtained results demonstrated that whole life cycle carbon footprint of the substation is 1099.91 tCO2e. Among them, the carbon emission in the construction stage is the highest, accounting for 59.52% of total emission amounts. Based on the sensitivity analysis method, it can be seen that compared with other links, the sensitivity extent of concrete, power consumption, steel, alkanes and cycloalkanes is higher. It is suggested to improve the production process of concrete and steel, increase the proportion of clean energy power generation, and realize the low-carbon transition.
