 This study assessed the contribution of sewage treatment plants, STPs, degree house gas, GHG emissions in the state of Hinnokal Pradesh, India. It found that electricity consumption by STPs was responsible for the largest share of emissions, at 43%, followed by the activated sludge process at 31%. Storage of sludge in landfills also contributed significantly, at 24%. Finally, transportation accounted for only 2% of the emissions. Overall, the STPs in Hinnokal Pradesh had the potential to contribute 48,237 metric tons of carbon dioxide equivalents, TCO2EQ, per year. These findings suggest that process-level modifications are needed to reduce GHG emissions from STPs in Hinnokal Pradesh. This article was authored by Puvashama, Satish Kumar Bodwaj, R. K.
