reduced between an ambient light intensity of at least 20 lux and 0 lux; (b) the automatic brightness control is activated in the home-mode condition or the on-mode condition of the television as set by the supplier. Cars For motor-vehicle it isn't electrical efficiency that is indicated but carbon dioxide emissions in grams per kilometre travelled. Other information that is indexed for the energy label is: its brand its model its version its fuel its transmission type its weight the different consumptions of fuel mixed consumption urban consumption extra-urban consumption the CO2 emissions in grammes per kilometre Tyres European tyre labels came into force in November 2012. The tyre labelling will show three tyre performance attributes; rolling resistance, wet grip and external rolling noise. The tyre label apply to: Car and SUV tyres Van tyres Truck tyres with the exception of: Tyres for cars made before 1 October 1990 Re-treaded tyres Motorcycle tyres Racing/sports car tyres Studded tyres Spare tyres Vintage car tyres Professional off-road tyres. Society and culture Impacts on purchasing decisions A trial of estimated financial energy cost of refrigerators alongside EU energy-efficiency class (EEEC) labels online found that the approach of labels involves a trade-off between financial considerations and higher cost requirements in effort or time for the product-selection from the many available options – which are often unlabelled and don't have any EEEC-requirement for being bought, used or sold within the EU. Moreover, in this one trial the labeling was ineffective in shifting purchases towards more sustainable options.
