‘Carbon dioxide emission from new vehicles alarming’

New Delhi, June 2 (IANS) New cars, especially those which hit the Indian roads after 2005, are emitting more carbon dioxide, a green house gas responsible for global warming, Centre for Science and Environment (CSE) said here Monday. The green organisation said an increasing carbon emission hints at an increased oil consumption feature of these new vehicles, be it a bike, small petrol car, diesel car or even the much desired sports utility vehicles (SUVs).

The information has emerged from the CSE’s analysis of the CO2 emissions tested by the Automotive Research Association of India (ARAI) in vehicles produced in different time period - 1991-96, 1996-2000, post-2000 and post-2005.

The CSE said after analysis it found that while a post-2000 petrol car model with 1,400 cc engine emits 143 grams of CO2 for every km it runs, the post-2005 models of same engine size emit 173 grams per km. Here fuel economy drops from 16 km per litre to 13 km per litre.

Similarly, while a SUV model with engine size less than 3,000 cc of 1996-2000 vintage emits 189 gm of CO2 per km, the emission has reached 256 gm for the same distance of travel in post-2005 models.

The CSE added that the total carbon dioxide emissions load from vehicles is increasing in cities like Delhi. Cars and two-wheelers contribute maximum to the total CO2 emission load from vehicles in Delhi - as much as 60 percent.

“Only in five years, between 2002 and 2007, the CO2 emissions load from cars has increased by 73 percent and from two-wheelers by 61 percent. This has serious implications for energy impacts,” the CSE said.

However, it gave almost a clean chit to public transport buses which “contribute much less of CO2 load - 20 percent”.

“But it is important to note buses carry several times more people and consume significantly less fuel per passenger. CSE’s estimate for Delhi’s BRT corridor shows that per capita energy consumption can be eight times higher in cars than buses,” the CSE added.
