Carrollian conformal field theories (carrollian CFTs) are natural fieldtheories on null infinity of an asymptotically flat spacetime or, in general,geometries with conformal carrollian structure. Using a basis transformation,gravitational S-matrix elements can be brought into the form of correlators ofa carrollian CFT. Therefore, it has been suggested that carrollian CFTs couldprovide a co-dimension one dual description to gravity in asymptotically flatspacetimes. In this work, we construct an embedding space formalism forthree-dimensional carrollian CFTs and use it to determine two- and three-pointcorrelators. These correlators are fixed by the global subgroup ISO(3,1) of thecarrollian conformal symmetries, i.e., the Bondi--van der Burg--Metzner--Sachssymmetries (BMS). The correlators coincide with well-known two- and three-pointscattering amplitudes in Minkowski space written with respect to a basis ofasymptotic position states.
