There are also other ways in which a smart city can help the environment

Less pollution

Less emission meaning less pollution which also means avoiding diseases. Ride-sharing and bike-sharing are common services provided in smart cities which have less emission. Also, the need for less fuel. More people will like to walk in pedestrian-friendly streets, driving battery electric cars or riding bikes.


A smart city can also save us from thousands of common problems caused by urban transport systems. As such, these areas could benefit from energy-efficient IoT systems like traffic light, GPS and cameras. The latter aids in keeping the traffic moving.

A case in point, Dutch city Eindhoven implemented street lights that turn on and off depending on how busy the street is.

3. Monitoring living conditions

In addition to the above paragraph, sensors and cameras are already being utilized to track air quality, temperature, sound levels among others

These sensors detect problems earlier before it creates a big problem later.

3. Improves Urban Solid Waste Management

The environment has an extraordinary self-cleaning capacity and also have ability to heal itself .

According to Synova, globally, we produce an astonishing 3.6 million tonnes of municipal solid waste each day , more than our planet can sustain.

Using technology to we deal with garbage, can lessen the strain we place on the environment.

Smart waste solutions can be great to our environment. The BigBelly solar-powered trash compactorsfor instance, use smart sensors to know when to begin compacting.

Additionally, the containers can communicate with local waste management organization through the cloud to signal when they need to be emptied. As a result of which garbage trucks, carbon footprint and harmful emissions are reduced.

4. Smart technology- efficient public utilities

Efficient public utilities smart technologies are giving cities the required tools to effectively reduce water lost. Smart electric grids which allows for two way communication between electricity providers and consumers can help identify times of peak usage and outages.

Smart Metering

Cape town, South Africa citizens has utilized smart metering to overcome ongoing water crisis. And customers gets a daily bill that displays their water consumption.


Everyone benefits from smart cities and it could be a win-win situation for everyone. Even though, the cost might be higher, an eco-friendly city in the form of smart infrastructure will be a necessity for a better quality of urban life.
