RAJKOT GHG EMISSIONS

RAJKOT GHG EMISSIONS INVENTORY 2015-16

GHG Emission Inventory accounts for greenhouse gas emission from fossil fuels and electricity consumed in city through various activities like stationary fuel combustion, electricity consumption, and municipal solid waste and sewage degradation. The present GHG inventory is prepared for the time period of 2011-12 to 2015- 16 to map the overall trend of GHG emissions. The cumulative emissions mentioned in the report are for the year 2015-16.

Rajkot is the fourth largest city in the state of Gujarat, India, after Ahmedabad, Surat, and Vadodara. Rajkot is the 35th largest urban agglomeration in India and the 22nd fastest-growing city in the world. As estimated in study, the total GHG emission for Rajkot City was 2.01 million tonnes of carbon dioxide equivalent (CO2e) in the year 2015-16. Taking this into consideration, the average per capita GHG emission for the year 2015-16 for the Rajkot city area was 1.40 tonnes of CO2e, which is less than India’s per capita GHG emission 1.56 tCO2e for the year 20103.

The Residential Buildings Sector has the maximum contribution of 33% to the total GHG emissions, followed by the Transportation Sector, which has a share of 27%. Manufacturing industries and Construction, Waste Sector, and Commercial/Institutional contributed about 17%, 13% and 10% respectively to the overall GHG emissions at the Community level (see figure-1).

About 15.7 Million Giga Joule (GJ) of energy is consumed in Rajkot city. Transportation Sector has the maximum contribution of 49% to the total energy consumption, followed by the Residential Buildings Sector, which has a share of 30%. Manufacturing Industries and Construction, and the Commercial/Institutional Sector contributed about 15% and 5%respectively to the overall energy consumption at the Community level. In terms of energy supply, grid electricity caters to 27.8% of the energy demand while it contributes to 57.1% of the GHG emission, largely due to India’s fossil coal based electricity generation (see figure-2). Electricity use has been in- creasing in the Residential, Commercial/Institutional and Industrial sector. Petroleum products account for 23.7% of the GHG emission. Use of Natural Gas, Liquefied Petroleum Gas (LPG), and kerosene accounts for 12%, 5.2% and 1.7% of the total GHG emission respectively. It should be noted that use of piped natural gas has been in- creasing in the Residential and Commercial/Institutional sector in Rajkot.

Operations of the Rajkot Municipal Corporation emitted 55,080 tCO2e, contributing to 2.7% of the city’s total GHG emission. Energy use for provision of water supply is the largest source of municipal GHG emission with a share of 57.6%. Street lighting, on- road transportation in municipal vehicles, sewage treatment, transportation, energy use in buildings and energy use in SWM transfer stations are other significant sources having a share of 22.4%, 10%, 5.1%, 1.9% and 0.2% respectively.
