READING SPEAKING 43 A sustainable city should be eco-friendly, have green spaces, reduce air pollution and CO2 emissions, improve air quality, and protect natural resources. In other words, it should be an urban centre designed to improve its environmental impact while also granting a high-quality lifestyle to people. Green technology is a key factor which includes all aspects of city planning, including transportation, infrastructures, telecommunications, recycling and the use of renewable energy in homes and offices (over 100 cities now get at least 70% of their electricity from renewable sources such as hydro, geothermal, solar and wind!). This type of city is becoming essential to fight global climate change. Six characteristics of a sustainable city Cities can do several things to be called sustainable and must have these six characteristics: Make it easy to get around without a car: sustainable cities should create paths , bike bridges and sidewalks and encourage citizens to walk, ride, or use local transport; Add electric charging stations: hybrid and electric cars can dramatically reduce toxic emissions, so the presence of many charging stations is fundamental to encourage the use of those cars; Provide access to public resources and green spaces (parks and recreational areas); Improve waste management: programmes to minimise waste by recycling, composting, and reusing materials are crucial; Support urban farming, which improves food production and the environmental effects of food transportation. It includes vertical gardens, rooftop farming, community gardens, and encouraging schools and restaurants to grow food; Implement green architecture: green architects are discovering innovative ways to reduce the use of resources and gas emissions, from using natural building materials and solar panels, to improving ventilation and insulation , and planting more trees. 1 READING Completa le frasi. 1.
