Oslo - Norway 

The one of the wealthiest city in the world is so aggressive in implementing the plans to cut down carbon emissions with sustainable use of natural resources. Oslo is one of the few cities which has implemented the Traffic Congestion reduction program where the vehicles number plate will be communicating with the centralized system which suggests the commutator to reduce or increase speed. This technique would help in eradicating the traffic congestion. However, the city administration is in a thought process to completely ban the private vehicles on week days by the end of this decade. Its smart street light technology is helping to save 2/3rd of energy which was earlier utilized by the street lights. Oslo also has a comprehensive electric vehicle charging grid. This is really commendable. This Nordic city is going to distribute health chips to all its residents which will help to monitor their health.
