How can we improve the air quality in the city?


The most populated cities exceed the limits established in relation to nitrogen dioxide (NO 2) and particles with a diameter of less than 10 microns (PM 10). These pollutants are characteristic of cities and originate mainly as a result of the road traffic and especially by the use of diesel fuel. Poor air quality can affect the health of people living in these cities, especially the population with respiratory problems and children. As citizens, we can help reduce the emission of these compounds by introducing some canvas into our daily lives.

Steps to follow:

1.Most of the trips per city are less than 2.5 kilometers, for these distances, going on foot or by bicycle would be ideal, and avoiding the use of the car, that would improve the CO 2 emission.

2.Take advantage of the trip with people who make the journey similar to ours. We will save fuel and money, and reduce harmful emissions and traffic

3.The use of public transport involves about 15 times less energy per person transported and kilometer. Buses in many cities are being renovated with cleaner fuels, such as natural gas, which reduces NO 2 emissions by more than 80% and PM 10 by more than 95%.

4.We can save fuel if we drive at a moderate speed and smoothly, avoiding sudden braking or acceleration, using long gears and doing a good maintenance of the vehicle

5.Buying more efficient vehicles that run on low-emission fuels from city pollutants. For example, hybrid, electric or fueled vehicles such as natural gas or liquefied petroleum gas (LPG) and we do not oblige that smaller cars emit less pollutants than large vehicles.

6.We can improve air quality by reducing the consumption of air conditioners, using ceiling fans or simply making proper use of blinds and vents in homes.


  • There is a lot of documentation created by public agencies that can help us know how we can improve air quality in our cities.
