Air Quality Index (AQI)

The Air Quality Index (AQI) is a measure of the concentration of harmful pollutants in the air, typically expressed as a numerical value on a scale from 0 to 500. It is used to provide the public with information about the quality of the air they are breathing, and to alert them to any potential health risks associated with exposure to high levels of pollutants.

In the context of carbon management, the AQI is an important tool for monitoring the levels of carbon dioxide and other greenhouse gases in the atmosphere. By measuring the concentration of these gases, and comparing them to established safety thresholds, the AQI can help individuals and organisations to assess the potential impact of their activities on the environment, and to take appropriate action to reduce their carbon footprint.

For example, if the AQI indicates that the level of carbon dioxide in the air is approaching a critical level, a city or region may implement measures to reduce emissions from local sources, such as by promoting the use of public transit or encouraging residents to switch to more fuel-efficient vehicles.
