Green Party 3rd in London Election

Almost a month has past since the Green party achieved third place in London elections. Dose this show that London is becoming more environmentally conscious? It is a dream for many residents of London to make there home a nicer more green place to live. In the future all major city's will have to address the use of energy if they are to reach the UK governments target of 25% co2 reduction by 2025. Is third place a strong enough position for the Green party to kick start an environmental revolution or will they have to wait until a later date to push for the changes that need to be made?
