From an ecological protection perspective, clarifying the spatial and temporal transfer characteristics of embodied carbon in water transport trade among BRICS countries its driving mechanisms is great significance for precise formulation emission reduction policies. This study integrates multi-regional input–output model with LMDI decomposition method to quantitatively analyze bi-directional flow from 1995 2018, along spatio-temporal differentiation patterns. The are decomposed across three dimensions: scale, structure, intensity. By adopting a dual perspective time-series correlation, systematically uncovers cross-regional patterns emissions examines interaction pathways various effects throughout their dynamic evolution. finds that (1) shows trend transnational transfer, China being largest net exporter (35.15 Mt 2018), India South Africa as importers (−32.00 −1.89 respectively), Brazil Russia shifting exporters; (2) scale effect drives growth (contribution values: 1.23~119.72 export trade; 4.88~34.36 import trade), while intensity has suppressive role −59.08~−1.48 −20.56~−5.31 structural complex impact on −17.72~0.45 −6.84~13.93 trade). Optimizing structure can help reduce emissions; (3) higher Southeast Asia Northern Hemisphere, changes China’s (total 2018: 57.01 7.98 trade) significantly affect other countries. Based conclusions study, it suggested should strengthen cooperation achieve regional targets by optimizing transport, promoting energy reforms, advancing green technologies equipment, establishing regulatory system.
