Associate Professor Pavel Castka and Professor Charles Corbett from University of California have been investigating global adoption of eco-labelling schemes for the last two years.

Supermarket shelf items were packed with eco-labels such as green, fair trade, natural or biodegradable to suggest products had some form of environmental and social quality.

This includes things like fair trade coffee and chocolate; fish from sustainable fisheries; cosmetics (in particular shampoo) which are labelled as organic, natural, or not tested on animals.

Associate Professor Castka said offices and businesses and an increasing number of organisations used, for instance, paper that was labelled paper from sustainable sources, unbleached paper or paper manufactured with recycled water.

"Despite the economic downturn, the demand for environmentally and/or socially responsible products is growing. An international consumer watchdog TerraChoice has reported that the number of mostly labelled green products offered by retailers went up by 73 per cent between 2009 and 2010.

"The UK's Co-operative Bank said that expenditure on green goods and services grew by 18 per cent between 2008 and 2010 despite the economic downturn."

Associate Professor Castka recommended shoppers look for well-established eco-labelling schemes such as FSC or fairtrade.

"We found that the most adopted eco-labels were also the most consistent; with a third party behind the eco-label making sure that each certified product fulfills their criteria. "These eco-labels may not be the most stringent but they are stringent enough to make a difference. Presumably, if you purchase such products you expect a positive environmental and/or social impact.
