A rational model for emission allocation is a prerequisite for the correct measuring and reporting of the emission footprint in the choice among alternative logistics options. While much attention has been paid to national emission allocations, there has been less focus on cargo-level allocations. In this study, we propose an analytical framework for emission allocation in the maritime logistics chain. This framework provides an entire procedure for the emission allocation of logistics chains with different structures and transported cargoes. A set of universal principles are proposed to form the basis for any rational emission allocation scheme. This includes Completeness, No Redundancy, Simplicity, Fairness, Individual Rationality, Motivation, and Consistency. Three application examples are presented to illustrate this framework: a single logistics chain without return cargo, a single chain with return cargo, and partly uniform cargo with or without return cargo (container shipping). For each of these, different allocation schemes are tested and discussed.
