Attributional LCA is a system modelling approach in which exchanges are attributed to the functional unit of a product system by linking and/or partitioning the unit processes of the system according to a normative rule. This definition represents a modification from the UNEP/SETAC 2011 Shonan Database Guidance, where "inputs and outputs" has been replaced with the more precise term "exchanges" to reflect contemporary LCA terminology.
In attributional modelling, the system is constructed by systematically connecting unit processes based on predefined rules that determine how environmental burdens should be distributed or allocated amongst different products and processes. The approach typically relies on average data and established allocation methods, such as physical or economic relationships, to partition multi-functional processes.
