In recent years, Short-lived Climate Pollutants (SLCPs) have been found to be a major climate forcer after carbon dioxide (CO2). It has been Suggested that to remain under the target of 2°C by 2100, it is essential to reduce SLCPs along with CO2. Studies show that the glaciers in the HinduKush-Himalaya (HKH) region have been diminishing due to the impact of pollutants like BC and other SLCPs in addition to Greenhouse Gases(GHGs). Nepal, one of the countries in the HKH region, is also greatly affected.This study comprises the data development for inventory of SLCPs in
Nepal from energy use and non-energy activities in 2015. The scenario analysis till 2050 is done in the LEAP-IBC modeling framework using a bottom-up approach. The emissions of BC, methane, and PM2.5 were 40kt, 1 Mt, and 239 kt, respectively, in 2015 and have an increasing trend.The PM2.5 surface concentration in 2015 was 47μg/m3. However, the contribution of national emissions to this concentration is only about 30% while trans-boundary pollutants are as much as 50%. With the mitigating
measures undertaken, the emissions, as well as their climate impacts, can be reduced significantly compared to the business-as-usual scenario. 78% of BC, 78% of methane and 87% of PM2.5 emissions can be reduced in 2050 leading to an estimated avoidance of 29,000 lives and 1.7 million tons of loss in crop yield. We also find that the mitigation measures will bring an economic benefit of 2.7 times (in present value) more than the costs incurred in mitigation actions during the whole period of 2010 to 2050. The paper also indicates that a strong cooperation among countries needed is in the HKH region to tackle the issues in mitigation of
SLCPs.
