New Delhi closes coal-fired power plant as smog worsens during annual Diwali festival
Diesel generators and firecrackers also banned as dangerous air pollutants reach eight times the World Health Organisation’s safe limit
India’s environmental watchdog shut down a coal-fired power plant and banned the use of diesel generators in New Delhi as air quality plummeted in the world’s most polluted capital on Wednesday, the start of the Diwali festival.
New Delhi experiences suffocating smog every year around Diwali, when farmers in north India burn the stubble left behind after the harvest and revellers let off firecrackers. The onset of winter aggravates the problem as the cooler air traps the pollutants, a phenomenon known as inversion.
The Environment Pollution (Prevention and Control) Board, a statutory body, made the ruling as levels of PM2.5 pollutants in the air reached around 200 micrograms per cubic metre – eight times the World Health Organisation’s safe limit of 25.
“Difficult situations demand tough responses and solutions, and Delhi is faced with a really difficult situation each winter when air pollution levels spiral out of control,” said its chairman Bhure Lal in a statement.
The Board said the city’s Badarpur power plant, which has a capacity of around 700 megawatts, would be closed until March. The plant is due to shut down for good next July as India seeks to move away from heavily polluting fossil fuels.
