Air Quality

Air Quality is affected by air pollution. Major sources of this pollution are cars, buildings and homes. One of the key things we can do to ensure better air quality in Mississauga is to get out of our cars and take public transit, walk or cycle. We can also make our buildings, including our homes, more energy efficient. These changes will not only assist in improving air quality, but will also contribute to greenhouse gas emission reductions which help with the City of Mississauga’s climate change mitigation efforts.

The Air Quality Health Index was low risk 87% of the year in 2015.

The Air Quality Health Index is a scale designed to help understand the relative risk of air quality to human health using three pollutant indicators: ground-level ozone, fine particulate matter and nitrogen dioxide.

The Air Quality Health Index is measured on a scale of low risk, moderate risk, high risk and very high risk.

Managing Air Quality

The City of Mississauga helps reduce local air pollution by: providing residents with a number of alternative transportation options that help to get cars off the road; ensuring City buildings are energy efficient; and planting more trees. Some examples include:

  • Expanding public transit routes such as the new Mississauga Transitway.
  • Creating more bike lanes and pedestrian friendly neighbourhoods.
  • The City of Mississauga Hershey Centre utilizes an ammonia heat recovery system from ice-making operations which provides hot water and heating, advanced refrigeration controls and LED lights in the parking lot. These energy improvements have resulted in a 17% energy reduction with a 2 year cost savings of $134,128.
  • Fire Station 116 uses a geothermal renewable energy system for heating and cooling.
  • Mississauga’s Idling Control By-law encourages drivers to stop unnecessary vehicle idling. This reduces emissions from vehicles which reduces greenhouse gas emission and air contaminants.
  • Mississauga’s tree canopy has increased to 19% through the One Million Trees Mississauga program and other tree planting efforts.
