and to improve the air quality index. The pandemic and that related shutdown clearly
indicated that changes in policies and monitoring the economic check points could
solve many related environment issues.
8.2 Sectors Wise CO 2 Emission
Anthropogenic activities are the major source of CO 2 emission and greenhouse
effects. There are six major economic sectors which emit CO 2 and cause major
changes to our environment. Those six sectors are (1) industry which includes all
types of industrial activities, (2) power sectors which include the fossilized fuel
burning-based power generation, (3) public and commercial buildings, (4) surface
transport which includes both road and water transport, (5) residential, and (6) aviation [12]. Among these six sectors the power generation sectors emit majority of
the global fossil fuel-based CO 2 . Around 44.3% of total global CO 2 emission is
accounted to fossil fuel-based CO 2 emission. As till date, fossilized fuel burning is
the major power source throughout the planet. The industrial sectors are accounted for
around 22.4% global CO 2 emission. Among all the industries the cement producing
industries account for 8% of global CO 2 emission [7, 9, 10]. The next major sector
is surface transport which accounted almost 20.6% of total global CO 2 emission that
includes the road, rail, and water transports where the fossil fuel is used as an energy
source. The public sectors and the residential sectors emit 4.2% and 5.6% of global
CO 2 , respectively. The aviation sector is accounted for 2.8% of global CO 2 emission.
In Fig. 8.2 the sector wise global CO 2 emission share has been presented. Although,
the above sector wise global CO 2 emission scenario is general and account to the
global level of CO 2 emission. These could be different from country to country
