Air Quality Health Index (AQHI)

Why This Matters

Clean, healthy air is a central component of a sustainable natural environment. The quality of air affects our health and ability to be active in the outdoors and is a reflection of the type and amount of energy we use. To measure the quality of our city’s air, Peg uses the Air Quality Health Index (AQHI).

The AQHI is calculated based on relative risk of exposure to a combination of three common pollutants; Ground-level Ozone (O3), Fine Particulate Matter (PM2.5) and Nitrogen Dioxide (NO2). The AQHI is measured from 0 (No Risk) to 10+ (Very High Risk). Days without a recorded AQHI measure of 4 or more were considered low risk days.

Measure and Limitations

Recognizing that concentrations different pollutants have a serious effect on human health, the Government of Canada adopted the Air Quality Health Index (AQHI). The AQHI is designed as a health protection tool to help individuals “make decisions to protect [their] health by limiting short-term exposure to air pollution.” (GoC, 2016). The AQHI is “calculated based on the relative risk of a combination of common air pollutants that is known to harm human health (GoC, 2016)”; Ground-level Ozone (O3), Fine Particulate Matter (PM2.5) and Nitrogen Dioxide (NO2). To measure air quality using the AQHI, PEG reports on the percent of Low Risk Health Days.

11. Make cities inclusive, safe, resilient and sustainable

Cities are hubs for ideas, commerce, culture, science, productivity, social development and much more. At their best, cities have enabled people to advance socially and economically.

However, many challenges exist to maintaining cities in a way that continues to create jobs and prosperity while not straining land and resources. Common urban challenges include congestion, lack of funds to provide basic services, a shortage of adequate housing and declining infrastructure.

The challenges cities face can be overcome in ways that allow them to continue to thrive and grow, while improving resource use and reducing pollution and poverty. The future we want includes cities of opportunities for all, with access to basic services, energy, housing, transportation and more.
