In Germany Deutsche Bahn (German railway company) some time ago has released a beautiful educational video that explains the benefits of an environmentally conscious behaviour. Or course the video suggests that travelling by train produces less CO2 than travelling by car or by plane.
The interesting aspect of the project is the fact that DB encourages word of mouth with an ecological trick: for every view of the video, they will donate 10 cents to the “Bergwald Project,” which will use the money to plant new trees throughout Germany. A very nice idea, at first sight not very well executed since the video player has no immediate option to be embedded or shared with other people. Youtube where are you?
The agency behind the video is Peppermill Berlin.
