"Bright blue or green and white coloured buses, with “Zero Emissions” pasted on
the sides, are regularly being seen on the roads of the national capital,
Delhi. These are Delhi’s electric buses – a fleet of 150 launched in May this
year – which are in operation in addition to the existing fleet of buses that
run on compressed natural gas (CNG), carrying thousands of commuters across the
city every day.
CNG buses are known to release polluting gases such as carbon monoxide, carbon
dioxide and nitrogen oxides besides Particulate Matter (PM) 2.5 and ultrafine
particles. Electric buses, on the other hand, have zero emissions when they are
in operation as they run on batteries which are charged by electricity.
According to a recent study by researchers at the Kyushu University in Japan,
the complete electrification of the public transport system in Delhi, with
battery-operated electric buses, can have several “co-benefits” besides
combating air pollution. This is due to its virtue of being a zero-emission
transportation alternative.
The study, published on September 1 this year and titled
Quantifying the
multiple environmental, health and economic benefits from the electrification
of Delhi public transport bus fleet estimating a district-wise near roadway
avoided PM2.5 exposure, was published in the
Journal of Environmental
Management. The study developed an integrated quantitative assessment
framework to examine the benefits from the increased penetration of
electrification of the public buses in Delhi.
The study estimated the benefits of e-buses in a scenario where all the
existing public buses in Delhi are replaced by new electric buses. The study
claimed that in such a scenario, 74.67 percent of the total pollutant emissions
from the existing bus fleet in Delhi could be reduced. It also pointed out that
besides the reduction of emissions, the transition from CNG-based to
electricity-based buses could have several other “co-benefits” such as
increased energy efficiency, improved air quality and better public health."
