Delhi’s transport sector produces six times as much greenhouse gas emissions (GHG) as that of Kolkata’s, five times as much as Ahmedabad’s and three times as much as Greater Mumbai and Chennai, according to a study.
Delhi’s transport sector contributes 32% of the city’s GHG emissions—gases responsible for global warming—said the report, GHG Footprint of Major Cities in India, conducted by the Centre for Ecological Sciences of the Indian Institute of Science (IISc), Bangalore.
However, data presented to the Lok Sabha (lower house of Parliament) said that Delhi transport sector contributes only 28% to the total greenhouse gas emissions, excluding emissions from compressed natural gas (CNG) vehicles.
Despite a 187 km, seven-line metro network carrying 2.4 million commuters every day, private vehicles rose 92% over the last 15 years, even as buses and their ridership declined, according to Delhi’s Economic Survey 2014-15, as we will detail in part two of this series.
Delhi’s transport sector emits 12.39 million tonne of carbon-dioxide (CO2) equivalent, followed by Greater Bangalore (8.61) and Hyderabad (7.81). The transport sector in Hyderabad emits the greatest proportion (56.86%) of GHG emissions compared to other Indian cities.
The transport sector includes motor cycles, scooters and mopeds, cars and jeeps, taxis, buses, light motor vehicles (passengers), light motor vehicles (goods), trucks and lorries, tractors and trailers. Transport emissions of Chennai, Kolkata and Mumbai also include emissions from shipping.
