Swedish advertising company, Acne, put together a rather eye-catching advertising campaign for Flygbussarna, an airport coach bus service, to inspire individual car drivers to take the coach bus instead. An installation made up of 50 wrecked cars resembling a Flygbussarna coach bus was placed next to the highway leading to the Swedish airport. Acne used 50 cars to emphasize that a coach bus can seat up to 50 people whereas, on average, an individual car has only 1.2 people. Consider that with the fact that a coach bus releases no more carbon than 4 cars. The campaign also included a website where visitors could watch cars whizz past the installation. The website tracked the number of cars that drove by and how much carbon could have been saved if those drivers had taken a bus instead.
