University of Maryland, Urban Emissions Information, a study by researchers at the University of Massachusetts Amherst and Texas Tech University, Published by the United States National Academy of Sciences, has found that 78,000 deaths in India were already attributed to coal plants in 2018, the base year for the study. If all coal plants were installed in the pipeline, the deaths associated with them would increase to 1,12,000 annually. And this Lifetime effect These new plants are estimated to have 8,44,000 premature deaths.
“We run the model for the first time in 2018 by estimating the emissions of PM2.5, NOx and SO2 from all sources except power plants… We run the model again, adding power plant emissions from 2018… In the third run, we Add emission from planned. Plants, ”lead author Dr. Maureen Cropper told TOI. Then, mortality rates for stroke, ischemic heart disease, chronic obstructive pulmonary disease, lower respiratory infections, diabetes mellitus, and lung cancer were calculated.
They found that the ambient PM2.5 in 2018 was 53.5 / g / m3 – higher in the Indo-Gangetic Plain and in areas with higher coal-powered plants than in southern India – which would increase to 55.9µg / m3 if all plants Operations begin. With the new plants, the share of coal-fired power plants for PM2.5 will increase from 9% in 2018 to 13% across the country by 2030.
“in Odisha And Jharkhand, where planned plants have doubled coal capacity, has seen a 50% increase in deaths. “Bihar and West Bengal Large expanses of capacity in Jharkhand and Odisha are down and will experience significant health impacts from cross-border pollution under the assumption that current pollution control practices are continued. ”
Two things can change the scale of this effect in opposite ways – switching to cleaner fuel in homes and full implementation of new air regulations.
“in Bihar, Jharkhand, Odisha and Chhattisgarh, burn solid fuel for cooking in more than 75% of households; Is in Uttar Pradesh, Approximately two-thirds of families in West Bengal, Madhya Pradesh and Rajasthan. “When people are already accumulating too much PM2.5 from domestic air pollution, the effect of power plant emissions is much less than when they are not exposed to domestic air pollution,” explained Cropper.
And while there are regulations for thermal power plant emissions, notified in 2015, they are not being implemented. The study calculated that implementing the 2015 rules would reduce coal power plant PM2.5 by up to 70% every year.
