1 Scope

GB/T 46905-2025 is the Chinese national standard covering the carbon intensity of a port terminal - the emissions per container or per tonne handled, from the cranes and yard equipment, the shore power supplied to ships and the terminal's own buildings, and the grades a terminal is placed in. First edition, under the Ministry of Transport. It was issued on 31 December 2025 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the Ministry of Transport. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the assessment scope, calculation method, classification method, limits, and assessment method for the carbon dioxide emission intensity levels of wharves. This document applies to the assessment of carbon dioxide emission intensity levels for production operations at specialized container terminals and specialized coal and ore terminals.

3.3 Indirect CO2 emission Carbon dioxide emissions from production processes such as electricity and heat.

3.4 The sum of direct and indirect carbon dioxide emissions.

4 Scope of Assessment

4.1 Energy types assessed Carbon dioxide emission assessment should include the following energy sources.

---Fossil fuels such as diesel, gasoline, and liquefied natural gas;

---Electricity (purchased externally);
