    April 27, 2012 New York

    Since 2008 the New York City Department of Transportation has hosted Summer Streets, an annual celebration of the City’s most valuable public space–its streets. On three consecutive Saturdays in August, nearly seven miles of NYC’s streets are closed to cars and opened for people to play, walk, bike, and breathe. Summer Streets provides more space for healthy recreation and encourages New Yorkers to use more sustainable forms of transportation.

    Seoul's Weekly No Driving Day program is improving air quality, congestion and saving energy. Every year, two million cars stay off the road – decreasing traffic volume by 3.7%. CO2 vehicle emissions are being reduced by 10% - a total of 2 million tons of CO2, delivering annual savings of $50 million USD in fuel costs. The improved air quality is also improving the health of residents, saving the City millions annually. The program works because it is applied during weekdays, which encourages people to use alternate modes of transport to and from work.

    London is the largest city to have adopted a central area congestion charging scheme. It has led to a 20% reduction in four-wheeled traffic within the charging zone during charging hours, cutting an estimated 40-50 million litres of vehicle fuel consumption inside the zone and a total 100,000 tons CO2 emissions annually across London. The charge raises £122 M annually which is then spent on improving transport, including providing more buses, improving road safety and implementing energy efficiency in transport. The zone was further extended in February 2007, doubling its size, with initial estimates showing a 13% reduction in traffic in the new area covered. Monitoring of this extended zone has not yet been completed.
