In India, air pollution from the burning of fossil fuels in industries, biomass burning, agricultural residue burning and transportation is the fifth greatest cause of mortality. India's Indo-Gangetic Plains (IGP) region is one of the greatest source of emissions in India. The region is not only home to significant emissions of conventional pollutants but short lived climate pollutants (SLCPs) such as black carbon (BC), methane, tropospheric ozone, and hydrofluorocarbons. Recognising the importance of these pollutants, daily concentrations of BC, PM2.5 and PM10 were monitored in three districts of IGP during January 2015 to December 2016. The GAINS model was used for assessment of pollution effects, emissions of SLCPs, GHGs and identify appropriate control actions. The outcomes of the modelling showed that low carbon strategies register the greatest reductions in emissions compared to other control strategies. But the application of low carbon strategies may be constrained by the accessibility of clean fuels. In some cases, finance will be needed to support monitoring of air pollution and other supportive technologies.
