What was the Study?
The Centre for Science
and Environment (CSE), New Delhi, released a study, which examines questions
such as:
· How are some cities, which hold sizeable
shares of India’s urban population, positioned in the race for clean and low
carbon mobility?
· Which cities pollute and guzzle more than
the others from only urban commute?
· What is influencing the difference?
The vehicle
population is exploding in Indian cities. It took 60 years – from 1952 to 2008
– for the number of registered vehicles in the country to cross 100 million.
But that figure had doubled by 2015. At the same time, the share of public
transport in overall transportation modes is expected to decrease from 75.5% in
2000-01 to 44.7% in 2030-31.
The study assessed 14 cities to understand how the urban commute – the
way people travel in cities – contributed to air pollution and energy
consumption. The study ranks
the cities on the basis of emissions of heat-trapping carbon dioxide and toxic
pollutants like particulate matter and nitrogen oxides, as well as energy
guzzling from urban commuting.
What are the key findings?
- Bhopal tops for lowest overall emissions
and energy use from urban commute
- Kolkata and Mumbai emit least among six
megacities due to high usage of public transport and walking; Kolkata also
has short travel distances due to its compact form.
- Delhi, despite being the third highest
for high share of public transport trips, is at the bottom as overall emissions
and fuel use are highest due to the sheer number of people, high volume of
travel and personal vehicles, and long trip-distances.
- Megacities of Bengaluru, Hyderabad, and
Chennai show poor scores. They have lower share of public transport
compared to Delhi and yet have scored better than Delhi only because of
total travel volumes are comparatively lower given their population
levels. With growth and without adequate action they could get worse in
future.
- Though metropolitan cities have scored
better than megacities due to lower population, lower travel volume and
vehicle numbers, they are at risk due to much higher share of personal
vehicle trips and high growth rate
·
Increase in greenhouse
gas emissions from transport sector is highest among all the sectors in India.
Urban traffic is also the source of very high health-damaging toxic emissions.
What is the ranking of the 14 cities?
The rankings are given below, with the best one first.
Overall
emissions and energy consumption:
- Bhopal
- Vijayawada
- Chandigarh
- Lucknow
- Kochi
- Jaipur
- Kolkata
- Ahmedabad
- Pune
- Mumbai
- Hyderabad
- Bengaluru
- Chennai
- Delhi
Per-travel trip
emissions and energy consumption
- Kolkata
- Mumbai
- Bhopal
- Delhi
- Ahmedabad
- Lucknow
- Vijayawada
- Pune
- Jaipur
- Chennai
- Bengaluru
- Kochi
- Chandigarh
- Hyderabad
What should be done?
According to CSE,
the study proves that for clean and low carbon mobility, cities need policies
to:
·
stop
urban sprawl
·
reduce
distances between residence, jobs and recreation through compact urban forms
·
scale
up integrated public transport, walking and cycling
·
put
restraints on use of personal vehicles to avert pollution and climate crisis.
