For another thing, they ignored social aspects, trading often illusory environmental gains against development gains for poor developing-country producers that had contributed little to climate change in the first place (Muller 2007). These arguments, consumer confusion and methodological difficulty have more or less buried the idea of food miles labels. However, the enduring lesson is that ill-conceived methodologies may have unfair impacts, particularly on developing-country producers.8 This concern is most acute in the context of private sector labels, which are the least developed in terms of regulatory control or coordination. Ecolabels (like other quality-standard systems) will tend to work against smaller producers, for at least two reasons (International Trade Centre 2013, KPMG 2012).First, the fixed costs of certification and the inevitable restructuring of management systems are more easily borne by producers with larger revenues over which to spread those costs. Second, buyers tend to prefer larger producers, and will buy from them in preference to smaller producers. This is because when the buyer is tasked with ensuring the sustainability of the supply chain it is much simpler to do so with a smaller number of large producers.
