Less polluted cities in the world stand for sustainable mobility, the use of renewable energy and green extensive urban and distributed.
The cities less polluted planet Among the less polluted cities in the world stand out as some Auckland, New Zealand; the Canadian Calgary, Vancouver, Ottawa, Toronto and Montreal; Copenhagen, Denmark; Katsuyama and Kobe, Japan; Helsinki, Finland, Honolulu, US; Las Palmas and Vitoria-Gasteiz, Spain; Oslo, Norway; Salvador de Bahia, Brazil; and Zurich, Switzerland.
The recipes
for these objectives are diverse and set the line to follow. In some
urban transport is
basically sustainable means, such as Copenhagen, with 400 km of bike lanes.
Renewable energy sources are used significantly and successfully in many cold northern countries, despite the low temperatures induce a consumer heating and Norway (Oslo) and Denmark (Copenhagen), and America North and Canada.
Large green areas reduce air pollution in others, as in Helsinki or Vitoria (city veda Europe, 2012)
Also the geographical situation can help with benevolent climates like Las Palmas and Salvador de Bahia or favorable winds that sweep pollution from urban centers such as Honolulu. However, if there is
an attitude of respect for the environment assumed by
much of
the population can not
achieve these levels of
wellbeing with the environment. In Barcelona the network of bike lanes is 180 km. The fact that 80% of the municipality have 2% or less vertical favors the use of this means of transport, with about 100,000 daily trips.
Bicing Bicing and power complement to save the topography or distances long,
are a good alternative to motorized transport. Renewable energies are represented by the
biomass of the central Franca connected to the networks of heat and cold
city, solar
thermal to heat hot water, which are examples of the parking pools
Picornell or
cemetery of the Parliament; solar photovoltaic
and small wind to produce electricity, which is the maximum exponent
photovoltaic pergola Forum, but also include
The Way of Finestrelles or
around the park Guinardó. With regard to green areas, the city of
Barcelona has the disadvantage of a high population density and very limited physical space and built between Collserola, the Llobregat and Besos rivers and the sea. This is called
a compact. However,
the network include urban parks (967 hectares) and the part that lies within the municipality of Barcelona
Collserola Park (1795 Ha). Another fact worth mentioning is the proliferation of
vertical gardens that occurs for some time and that brings the green areas that do not have horizontal space.
