Eco labels can be somewhat of a minefield. Products can already have any number of different trademarks, logos and labels on them, and eco labels are another type of labelling to look out for. Luckily, there are many that you will probably already recognise and they are certainly worth checking for when shopping.
The International Standards Organisation (ISO) puts eco labels into three categories; those which are effectively a seal of approval from the organisation awarding the label, those which are simply a general claim, e.g. organic, and those which are graded, e.g. a five star hotel. The general claims can be the most tenuous unless they are backed up by official eco labels from a recognised organisation.
Eco labels range from the more well known such as the Fairtrade Mark or the Forest Stewardship Council (FSC) certification, to the more obscure such as the Demeter mark from the Biodynamic Agricultural Association which promotes and develops the biodynamic approach to farming, gardening and forestry. There are hundreds of eco labels internationally, so it would be impossible to recognise all of them. There are some, however, which it is worth looking out for when buying everyday items.
Organic certification from organisations such as the Soil Association, the largest UK certifier of organic produce
The Fairtrade Mark which ensures that producers have received a fair deal.
Forest Stewardship Council (FSC) certification which promotes sustainable forestry.
Marine Stewardship Council certification which promotes sustainable fishing.
