Only two of India's 10 most polluted cities, Delhi and Faridabad, are covered by the government's real-time air quality monitoring system, leaving more than one billion unprepared for toxic episodes, Greenpeace India said on Thursday, asserting that the country's air is now "deadlier" than China.
In its new analysis, the green body said that in the cities not covered, lack of real-time monitoring means inhabitants cannot check current pollution levels to protect themselves, and the government is unable to issue public warnings.
"Only two of India's 10 most polluted cities are covered by the government's real-time air quality monitoring system, leaving more than one billion unprepared for toxic episodes. The two cities covered are the capital Delhi and Faridabad, an industrial hotspot in northern India.
"In the cities not covered, lack of real-time monitoring means inhabitants cannot check current pollution levels to protect themselves, and the government is unable to issue public warnings," it said.
It said that around 88 million Indians - only 7 per cent of the population - live in the 33 cities that have online air pollution monitoring that is available in real time, meaning that less than 10 per cent of India's 380 urban agglomerations are covered.
Greenpeace India said that although the government runs several monitoring networks that cover more than 200 cities and towns, measurements in most are only taken twice a week and are not available in real-time.
"Instead, a manual monitoring system means samples must first be sent to a laboratory to be assessed," it said.
Comparing it with China, where levels in most cities are slowly dropping, the NGO said that in the latter its government has built a particle pollution monitoring network covering 400 cities and including 1,500 monitoring stations, all posting data online in real time.
"India's air is now more deadly than China's. All of the cities in the top 10 are experiencing levels of the particulate PM10 three-and-a-half times the annual legal limit and 10 times above international guidelines," the analysis said.
Noting that although media attention focuses on Delhi, the NGO said some of the worst pollution hotspots -- four out of the 10 most polluted cities -- are found in the coal mining state of Jharkhand.
"It has a population of 32 million but not a single official real-time air pollution monitor. Yet Jharkhand is the state googling for information about air pollution the most, well ahead of Delhi, per relative search interest metrics on Google Trends," it said.
Across the country, search interest on air pollution has
been rising steadily and reached the highest point on record -- at least since 2004 -- following the enormous pollution levels last October-November.
"Not a single city in northern India met international safety guidelines for particle pollution in 2015. Less than 10 per cent of the cities met India's national air quality standards, which are three times as high as the WHO safety guideline," it said.
The green body said that India's pollution levels have been rising at an "alarming" rate as coal consumption almost doubled and oil consumption increased 60 per cent from 2005 to 2015.
Its report last year showed that emissions from coal-based power plants were the largest source of increase in SO2 and NOx emissions in the country -- two key pollutants contributing to India's particle pollution levels.
The NGO said that organisations such as TERI and CSE, along with them, have started calling for a national action plan on air pollution to expand measures to reduce emissions from key polluting sectors -- power plants, industry, agriculture and transport -- beyond individual cities.
The national crisis has prompted measures such as new emission standards for coal-based power plants, restrictions on vehicles and the launch of a National Air Quality Index, it added.
