Beijing’s four-tier emergency response plan kicks in based on air quality index (AQI) forecasts and not actual recorded concentrations.

It has also shown that many interventions under GRAP should have kicked in much earlier based on forecasts rather than when particulate matter concentrations were already peaking.

Beijing’s four-tier emergency response plan kicks in based on air quality index (AQI) forecasts and not actual recorded concentrations. For example, their blue alert is implemented when AQI is predicted to be greater than 200 for a day— dust-control measures are enhanced, public transit is preferred, outdoor activities in schools are reduced and vulnerable people are alerted about health impacts. Their red alert or the severe most category comes into force when the AQI is forecast to be more than 200 for four to five days—a routine in Delhi.
