In the European Union, the transport sector is responsible for 31% of the energy consumption and for 21% of the GHG community emissions excluding aviation.
The evolution of the industrialised countries’ cities which currently gather the essential of human activities, has reinforced the concentration of the population in urban centres (Currently, 80% of the European population is concentrated in urban areas).
This fact reinforced the increase of the transport pollution up to 40% of greenhouse gases in the cities. Despite the public transport offer, the use of individual vehicles such as cars remains frequent. By habit, comfort, independence, freedom, users abandon their personal vehicle with difficulty. In the city, we frequently observe thus problems of roadway saturation and increase of pollution of the air, etc.
To reduce the energy consumed and the related pollution linked to the transports, an evolution towards less polluting new transportation methods is therefore necessary. We all observe more and more the promotion and the development of soft transportation methods: bicycle renting, electric cars, carpooling, tramway, etc.
Simultaneously, a virtual mobility, true alternative to physical mobility is developing. Thanks to the investments in the sector of the telecommunications development, new working methods are being developed and reduce physical movements: teleworking, video conferences, internet, high speed voice-data-images networks…
However, the benefits provided by the use of transports, and especially individual cars or airlines, are way greater than the felt benefits of reducing use of transports (environmental or economical benefits for instance). Obviously this appears in a context where people have no explicit incentives and are not accountable for commons (tragedy of the commons combined with game theory).
We’ll see soon how the tragedy of the commons hampers Energy Efficiency projects.
