When: 7 December 2015
Authorities in Chinese capital Beijing on 7 December 2015 issued its first-ever red alert on air pollution ordering schools to close due to hazardous air quality. Red alert is the highest possible state of caution.
The order was issued after acrid smog enveloped the capital for the second time in December 2015.
The order will last from 7am (local time) on 8 December 2015 morning until midday on 10 December 2015, when the weather is expected to change and blow away the smog.
The red alert was announced for the first time since an emergency air-pollution response system (four-tier system) was introduced in 2013.

The red alert was an upgrade from an orange alert issued on 5 December 2015. Orange alert is the second-highest of the four-tier system adopted in 2013.
Orange means outdoor construction should be halted, as well as the operations of companies that emit heavy pollution.
