Sikkim has embarked on the path of developing strategies to remain carbon neutral. The Sikkim Climate Inventory Monitoring System (SCIMS) is a first step in this direction. This brochure presents an overview of the SCIMS as well as key findings from its GHG inventory: Energy sector emissions have increased from 182 thousand tonnes CO2-eq in 2005 to 326.8 thousand tonnes CO2-eq. in 2015; The IPPU sector emitted 0.16 thousand tonnes CO2-eq. in 2015 as compared to 0.39 thousand tonnes CO2-eq. in 2005; Agriculture sector emissions have decreased from 163.99 in 2005 to 155.97 in 2015 Co2-eq. thousand tonnes; and GHG emissions from the waste sector increased from 33.01 thousand tonnes CO2-eq. in 2005 to 53.05 thousand tonnes CO2-eq. in the year 2015.
