Change The Weather has been a game changer for E.ON’s corporate reputation. It has succeeded in creating a leadership position for the brand around the topical and important issue of air pollution, and greatly strengthened E.ON’s appeal among corporate and consumer audiences. Not only that, but the campaign has had a tangible impact on public attitudes towards air quality. 18 media weather forecasts have been updated to include air pollution scores for the first time, and this has directly improved awareness and understanding around the problem. This is a corporate communications campaign with broader societal benefits.
