Smog chokes China cities for fourth day of ‘airpocalypse’

Key points:

• Dozens of cities issue pollution ‘red alerts’ for fourth day over China’s smog emergency
• Flights have been cancelled and schools have been closed for the day
• China struggling in its ‘war on pollution’ due to high demand for coal power

Some power plants and chemical producers in the region
had not scaled back operations in line with regulations, and drivers in
Beijing had also been ignoring traffic restrictions, according to China
Environmental News, the official publication of the Ministry of
Environmental Protection.
