The project was undertaken in four European cities: Berlin (Germany), Bucharest (Romania), Gdynia (Poland) and Rotterdam (the Netherlands). Young people themselves campaigned their ideas about renewables and energy efficiency to peers and adults, to the media, to the public and to policy makers. YOUTH had two principal aims: To promote understanding of smarter energy use in respect to urban traffic; to demonstrate the value of active participation of the younger generation in the decision making processes of local transport policy.
