Without switch to green energy, EVs can increase CO2 emissions in MMR by 7%-26%

Introducing electric vehicles (EVs) in the Mumbai Metropolitan Region (MMR) without adopting sustainable modes of generating electricity may lead to a 7% to 26% increase in carbon dioxide (CO2) emissions by 2050, finds a recent study by researchers at the Indian Institute of Technology-Bombay (IIT-B).

On the other hand, switching to greener modes of electricity generation can bring carbon dioxide emissions down by 27% to 41%.

The study by Deepjyoti Das, Pradip Kalbar and Nagendra Velaga was published in the peer-reviewed Journal of Cleaner Production on May 1. Das is a PhD scholar at the Centre for Urban Science Engineering (CUSE), Kalbar is an assistant professor at CUSE and Velaga is an associate professor in the Department of Civil Engineering of the institute.

They found that transport carbon dioxide emissions can rise significantly if EVs continue to be charged with electricity generated from fossil fuels.

“EVs can be a better solution than internal combustion engines (ICE) if the major fraction of the electricity used to charge the batteries is produced from renewable energy and there is minimal transmission and distribution loss in the grid,” said Das.
