GHG footprint – City and sector

Aggregation of GHG emissions of all sectors reveal that GHG emissions in major cities in India ranges from 38633.20 Gg/year (Delhi), 22783.08 (Greater Mumbai), 22090.55 (Chennai), 19796.60 (Greater Bangalore), 14812.10 (Kolkata) to 13734.59 (Hyderabad). 

Sector wise GHG footprint analysis for Delhi city reveals that transport sector leads the carbon emission (32.08%) followed by domestic sector (30.26%). The sector-wise carbon emissions analysis show the relative higher share for transportation sector in  IT (Information Technology) giants of India – Bangalore and Hyderabad. Emissions from transport sector ranges from 43.83% (Greater Bangalore) and 56.86% (Hyderabad) due to lack of appropriate public transport system in these Cities and haphazard growth due to unplanned urbanisation has led to large scale usage of private vehicles.

Environment Quality and lower vehicle density in the city:

Bangalore faced bundh on April 18 and ambient noise and air pollution levels at various locations in Bangalore was low (compared to the previous day, that is April 17), as per the data of Karnataka State Pollution Control Board (KSPCB): Residual suspended particulate matter (RSPM) reduced by as much as 55 % in some areas, while nitrogen dioxide (NO2) and sulphur dioxide (SO2) went down to 64 % and 16 % respectively. This highlights the role of transportation sector in higher GHG levels in major cities of India and the need for policy interventions and effective implementation.
