8. San Francisco, U.S
The high level of recycling is the main reason behind San Francisco’s growth as one of the greenest cities in the U.S. The city government has a mission to make the city zero waste by 2020. The wastes from residents and other places directly goes for recycling instead into the trashes. The non-biodegradable plastic bags are also banned in the city back in 2007.
The efficient environmental programs and policies in San Francisco actively encourage the use of renewable energy. In nearby future the city relies more on renewable energy sources like solar power, wind power, hydro-Geo thermal power and biofuel than fossil fuels. Thus the city can become greenish and healthier than before.
There are many community benefit programs in San Francisco. The cycling, vanpool, electric transportation and sharing of rides in the city help to save some money and to reduce emission of greenhouse gases.
