Research has analysed the efficiency of domestic fridges, testing the energy label declarations over a two-year period between 2009 and 2011.
Philip Sellwood, chief executive at the Energy Saving Trust, a social enterprise group with a charitable foundation, called for more to be done to address the findings of the project.
We need to address the fact that consumers across Europe are not maximising the energy saving benefits stated by millions of products.
There is an obvious need to recoup any potential savings through establishing more rigorous market surveillance and standards across energy efficient products and labelling.
The European Commission has recognised that this energy wastage is a problem, and is keen to ensure a compelling climate of compliance across all aspects of energy efficiency.
The Energy Savings Trust will tackle the problem with mystery shoppers, who will test products in an attempt to prevent misleading energy claims.
MarketWatch, as the scheme will be known, will be a three-year programme with more than 300 inspections in shops and 300 in online stores.
