The purpose is to explore barriers that affect the possibilities for retailers to offer environmentally sustainable distribution to consumers. Empirically, the paper relies on three interviews with retailers. Several barriers are identified, and a categorisation of these is described. Two of the most prominent barriers are suggested to be within the market barrier category, specifically that the retailers perceive to be unable to fully trust what the LSPs offer in terms of environmental distribution alternatives, and that the lack of consensus between LSPs on how to measure the impact.
