The Sustainable Wine Roundtable (SWR) has launched the initial phase of its Global Reference Framework (GRF), a benchmarking scheme aimed at evaluating various sustainability standards against a common criteria. The scheme will not replace existing standards but will provide retailers with a way to compare them. The GRF currently assesses nine areas of sustainability and has evaluated seven certifications. The SWR is also considering a sticker for bottles that have been GRF approved.
