The focus of improving the environmental footprint of the out-of-home advertising portfolio is the digitalisation of media displays in public spaces. The outdoor advertising industry has been working on increasing efficiency and saving energy for many years. We aim to operate our business model as efficiently and therefore as resource-efficiently as possible. For example, we have worked on the use of improved LED technology, individually controlled screen brightness depending on the surrounding light conditions, shutting down the devices at night, and adjusting the colour contrasts. These and other measures not only reduce power consumption but also significantly increase the service life of digital advertising media.
