When hundreds of delegates to the World Economic Forum’s India summit arrive in Delhi this weekend, one of the first things that will strike them about India’s fast-growing economy is the low-lying soup that hangs over the capital city.
Campaigners are concerned that the winter “fog” in Delhi, ranked as the world’s most polluted international city by the World Bank, has come earlier this year.
By some estimates this week, sulphur dioxide and carbon monoxide levels have been well over safe levels.
The Central Pollution Control Board in Delhi said that sulphur dioxide and carbon monoxide levels had fallen considerably over the past eight years, although the latter remains above the prescribed standard. However, it had registered a rise in particulate matter (dust), which it put down to construction work for the Commonwealth Games and Delhi metro.
The capital is estimated to have 5.5m cars on its roads, an increase of 57 per cent over eight years.
