IIT-K and ICCT study suggest adoption of EVs to improve air quality, health benefits in every state by 2040
The widespread adoption of electric vehicles (EVs) with robust power plant emission controls and power sector decarbonisation policies will yield net air quality and health benefits in every state in India by 2040.
The study carried out by researchers from the Indian Institute of Technology Kanpur (IIT Kanpur) and the International Council on Clean Transportation (ICCT) estimates vehicle and power sector emissions, air quality, premature mortality, and avoided health damages in India under an ambitious EV sales scenario between 2020 and 2040, with and without robust power sector emission control and decarbonisation strategies.
The findings for 2030 and 2040 suggest that stricter emission control strategies tend to be more effective at avoiding premature deaths than ambitious decarbonisation strategies apart from various benefits.
Combining the two strategies maximizes the benefits of EVs and brings improved air quality in every Indian state in 2040 compared to the baseline in 2040. This results in as many as 70,380 avoided premature deaths, equivalent to avoided health costs of up to $80.7 billion (2020 U.S. dollars) in 2040 alone.
“This study is a clear indication that EVs are the future and are here to stay and the benefits of its usage can lead to a better quality of life by 2040. We at IIT are proud to be associated with a landmark research and would like to thank ICCT for this wonderful and path breaking collaboration.” said Prof Abhay Karandikar, director IIT-Kanpur.
“EVs are the future, but we must be careful about the transition phase and source of energy for charging the EVs. Our simulations on air quality show stringent emission controls at power plants and their decarbonisation in a phased manner is the way forward,” said Mukesh Sharma, professor at IIT-Kanpur and co-author of the study.
“Indisputably, there are benefits from decarbonizing the electricity grid and improving power plant emission controls, and we see those policies are valuable irrespective of the level of vehicle electrification,” said ICCT India Lead Anup Bandivadekar.
“The idea that electrification without cleaning up the grid would backfire in terms of air quality is largely untrue. These findings highlight the societal benefits of EVs, and they can be maximized not by delaying electrification, but when policies for power sector emission control and decarbonisation are implemented in parallel with vehicle electrification strategies.” said Arijit Sen, an associate researcher at ICCT and the study’s lead author.
The study takes the national and gridded emissions output data from various vehicle and power sector scenarios to generate national and state level air quality values using the WRF-Chem model, particularly focused on fine particulate matter (PM2.5) concentration.
In 2030 and 2040, there are PM2.5 concentration decreases for all scenarios, which indicates improved air quality nationally. At the state level, barring a slight worsening in air quality in Ladakh that is within model error tolerance, air quality improves or is steady for all states in all 2030 and 2040 scenarios compared to baseline of the same year.APSC Notes brings Prelims and Mains programs for APSC Prelims and APSC Mains Exam preparation.
