Port full life cycle carbon emission accounting method

The invention discloses a port full life cycle carbon emission accounting system and method, and the method at least comprises the steps: a construction stage: dividing the construction stage into three main activity links: building material production/disassembly, building material transportation, construction equipment operation and energy supply; in the operation period, the port operation period comprises three main activity links of equipment operation, auxiliary production and auxiliary production; in the discarding period, the dismantling and discarding process is divided into two main activity links of a port discarding operation stage and a dismantling treatment stage; respectively constructing a carbon emission accounting method, and constructing a theoretical model of carbon emission accounting in the whole life cycle. According to the invention, systematic accounting and comparison are carried out on the carbon emission of the whole life cycle of the port, which is beneficial to emphatically optim
