Industries in Ahmedabad cause highest proportion of pollution compared to other major cities

By Our Representative
A recently report by the Centre for Ecological Sciences of the Indian Institute of Science, Bengaluru, has found that industrial pollution remains the main cause of worry for Ahmedabad. The study has said that out of 9,124.45 Gg CO2 emitted in Ahmedabad, industry alone accounts for 22.41 per cent, which is highest of the six other comparable cities -- Delhi, Greater Mumbai, Kolkata, Chennai, Greater Bengaluru, and Hyderabad.
As against Ahmedabad's 22.41 per cent of pollution caused by industry, the study says, just about 7.9 per cent of pollution is caused by industry in Delhi and Greater Mumbai, followed by Hyderabad's 11.38 per cent, Greater Bengaluru's 12.31 per cent, Kolkata's 17.66 per cent and Chennai's 20.25 per cent.
As against industrial pollution, the report says that Ahmedabad ranks fifth in causing domestic pollution with 27.9 per cent of total CO2 emitted -- compared to Hyderabad's 17.05 per cent, Greater Bengaluru's 21.6 per cent, Delhi's 30.26 per cent, Greater Mumbai's 37.2 per cent, Chennai's 39 per cent, and Kolkata's 42.78 per cent.
As for the third most important pollutant, transport, Ahmedabad's transportation accounts for 25 per cent of all pollution, ranking it fourth. The comparable figures for other cities are -- 13.3 per cent for Kolkata, 19.5 per cent for Chennai, 17.4 per cent for Greater Mumbai, 32 per cent for Delhi, 43.5 per cent for Greater Bengaluru, and 56.5 per cent for Hyderabad.
The study estimates greenhouse gases (GHG), footprint of GHG emissions (in terms of CO2 equivalent) and explores the linkages with the population and GDP. GHG footprint (aggregation of carbon dioxide equivalent emissions of GHG) of Delhi was found to be 38,633.2 Gg, Greater Mumbai 22,783.08 Gg, Kolkata 14,812.10 Gg, Chennai 22,090.55 Gg, Greater Bengaluru 19,796.5 Gg, Hyderabad 13,734.59 Gg, and Ahmedabad 9,124.45 Gg CO2.
Titled ‘Renewable and Sustainable Energy’, the report has been prepared by a team of researchers and students headed by Prof TV Ramachandra, from Energy and Wetlands Research Group, Centre for Ecological Sciences and associate faculty at the Centre for Infrastructure, Sustainable Transportation and Urban Planning (CiSTUP), Indian Institute of Sciences.
The team studied the cities of Delhi, Greater Mumbai, Kolkata, Greater Bengaluru, Hyderabad, Ahmedabad, Coimbatore, Bhopal, Pune and Kochi.
