Futuris Episode 4 (2010): "The City and the Sky"

With a population of more than 10 million, Paris belongs to a group of 20 so-called “megacities”. The city is now at the centre of a European research project that is investigating the effect street pollution is having on the climate and atmosphere. However, the aim is not just to trace the pollution and its impacts on the urban scale, but rather to see how one city can have an impact on a continental or even global scale.
