A sustainable city is an urban development designed to have a positive impact on the environment, society and the economy. Sustainable initiatives are built into the fabric of the city to minimise pollution, waste and carbon emissions and give something back to society or the natural environment.

A sustainable city is an urban development designed to
have a positive impact on the environment, society and
the economy. Sustainable initiatives are built into the
fabric of the city to minimise pollution, waste and carbon
emissions and give something back to society or the
natural environment.

that transport efficient, affordable and eco-
friendly is one way to help build a sustainable
city. Examples include electric metro or tram
services to help reduce carbon emissions
from vehicles on the road.
Creating sources of renewable energy for use
within the city is another way to help make
urban areas more sustainable. This could
involve city-funded solar farms to provide
energy and improve air quality.
The buildings that make up a sustainable city
are equipped with an array of technologies to
make them greener, such as natural building
materials, solar panels, smart systems for
heating and cooling and enhanced insulation
and ventilation. Green buildings can reduce
carbon emissions by almost a third.
