Digital signage: A sustainable advantage

The results from an extensive study into the carbon emissions of digital signage compared with those of traditional signage, released today, show that the carbon consumption of a projected display is 7.5 per cent lower than a traditional poster package.

The estate of 150 High Street stores hypothesised for the study showed a carbon saving over three years of 29.74 tonnes of carbon dioxide equivalent (tCO2e) following the change to a digital window display solution. This is equivalent to the total energy consumption of a typical UK household for more than five years.

The independent study, commissioned by MediaZest, co-sponsored by Cisco and Panasonic, and carried out by leading consumer research company ROI Team and Brunel University show that the carbon consumption of a projected display is 7.5% lower. It takes into account the emissions “from warehouse to warehouse” and compares all aspects of both types of installation, performance, maintenance and decommission; assessing consumptiom on electricity, diesel paper and ink.

The digital display analysed consisted of a Panasonic PT-D4000projector, which was chosen for its reliability and flexibility with its dual lamp system., 3M Vikuiti film applied to the window, and a Cisco media player. All changes of content are sent via a broadband line, thus eliminating repeated printing of materials and road distribution. The lifetime of the display was set at three years.
