GB/T 46530-2025 Grades and evaluation methods of carbon dioxide emission intensity for commercial ships
Abstract
This document specifies the classification of carbon dioxide emission intensity levels for operating ships, the determination of classification boundaries, and the requirements for grade assessment.
This document applies to the assessment of carbon dioxide emission intensity levels for domestic sea-going ships that are intended to enter the domestic waterway transportation market, have a gross tonnage of 400 tons or more, and are primarily powered by carbon-based energy; as well as for inland waterway vessels that are powered by traditional methods, electric propulsion, or hybrid propulsion. The applicable ship types and navigation areas are determined in accordance with Appendix A.
