Improving health and reducing costs through renewable energy in India

This study assess­es the impact of ambi­ent air pol­lu­tion on human health in India. The report quan­ti­fies both the health and eco­nom­ic costs asso­ci­at­ed with PM2.5/PM10 expo­sure. The analy­sis first assess­es the impacts of ambi­ent air pol­lu­tion from all sec­tors of the Indi­an econ­o­my. It then quan­ti­fies the spe­cif­ic impact of the Indi­an pow­er sec­tor, assess­ing the health ben­e­fits of increased share of renew­ables in the Indi­an ener­gy and pow­er sec­tor. The eco­nom­ic sav­ings result­ing from improve­ments in air qual­i­ty are analysed based on three dif­fer­ent ener­gy sce­nar­ios for the years 2020, 2030, 2040 and 2050:The Busi­ness-as-Usu­al sce­nario (BAU), rep­re­sent­ing India’s present cli­mate poli­cies rolled out until 2016. The NDC sce­nario (NDC), designed to chart out the strate­gies need­ed to achieve the tar­gets laid out in India’s NDCs. The NDC PLUS sce­nario (NDC PLUS), adopt­ing strate­gies for deep­er decar­bon­i­sa­tion over and above the NDC sce­nario. The study employs a five-step method­olog­i­cal approach includ­ing: ener­gy-sce­nario build­ing, emis­sions mod­el­ling, air-qual­i­ty mod­el­ling (dis­per­sion), health impact assess­ment and eco­nom­ic impact assessment.




Policy messages

Key pol­i­cy mes­sage 1: India can marked­ly improve the liveli­hoods of its cit­i­zens by reduc­ing ambi­ent air pol­lu­tion. In the busi­ness-as-usu­al sce­nario, dur­ing 2020 almost 500,000 peo­ple will die pre­ma­ture­ly due to expo­sure to par­tic­u­late mat­ter (PM10); this num­ber would rise to 600,000 pre­ma­ture deaths dur­ing 2030 and 830,000 dur­ing 2050. By mov­ing to the NDC PLUS path­way, more than 200,000 pre­ma­ture deaths can be avoid­ed in 2050.

Key pol­i­cy mes­sage 2: India can sig­nif­i­cant­ly cut eco­nom­ic loss­es by green­ing the econ­o­my and deploy­ing renew­able ener­gy sources. Fol­low­ing the busi­ness-as-usu­al path, eco­nom­ic loss­es relat­ed to health costs could increase from INR 4.6 tril­lion (USD 64.6 billion2 ) in 2020 more than two-fold in 2030 and more than ten-fold to INR 47 tril­lion (USD 660.3 bil­lion) in 2050. How­ev­er, by fol­low­ing the NDC PLUS path­way, eco­nom­ic loss­es in 2050 could be reduced by as much as INR 12 tril­lion (USD 168.6 billion).

Key pol­i­cy mes­sage 3: India should con­sid­er build­ing and fol­low­ing even more ambi­tious ener­gy path­ways. Even the most far-reach­ing sce­nario pre­sent­ed in this report (NDC PLUS) is insuf­fi­cient­ly ambi­tious to pre­vent a 4.3 % reduc­tion in Indi­an GDP and an increase in pre­ma­ture deaths in 2050 com­pared with 2020 levels.
