The cleaning up of waste present in transboundary rivers, which requires the cooperation of di erent authorities, is a problematic issue, especially when responsibility for the discharge of the waste is not well-defined. Following Ni and Wang  we assume that a river is a segment divided into several regions from upstream to downstream. We show that when the transfer rate of the waste is unknown, the clean-up cost vector provides useful information for estimating some limits in regard to the responsibility of each region. We propose a cost allocation rule, the Upstream Responsibility rule, which takes into account these limits in distributing costs \fairly" and we provide an axiomatic characterization of this rule via certain properties based on basic ideas concerning the responsibility of regions.
