Bellary, Tumkur) of the state contribute significantly to the emission. due to indiscriminate disposal. Wastewater generated in urban areas is either partially treated or
untreated and is discharged to the water bodies. Figure 23 presents the emission from
wastewater indicating higher emissions from the major cities. Emissions from the
transportation sector include CO 2 , CO, NO x , CH 4 , SO 2 , PM, HC, which accounts
to 38,440.56 Gg. Figure 24 illustrates the spatial distribution of emission from the
transport sector in Karnataka with the major contributions from Bangalore, Kolar,
Chikballapur, Tumkur and Mysore districts due to higher number of vehicles.
4.4 Carbon Ratio (CR) or Carbon Status in Karnataka
The carbon status of a region or carbon ratio (CR) refers to the ratio of sequestered
carbon in the ecosystems to emissions aggregated from all sectors or activities. CR
values greater than 1 indicate carbon sequestration higher than emissions. Gridwise carbon sequestration and emission were computed for 2019. Figure 25a and
b give the grid-wise carbon sequestration and emissions during 2019. The annual
sequestered carbon is about 16.1 Tg, while emission is 150.65 Tg, which highlights
about 11% of the emission is sequestered by forest ecosystems in Karnataka. The
districts or grids in the Western Ghats region have good sequestration potential with
the least emissions compared with other regions. High carboemitting districts include
Bangalore, Mysore, Dharwad, Bellary, and Raichur. CR ratio computed grid wise is
