Eco Car Myth -
vehicles cause more pollution than many 4 X 4’s
recent study reveals that some of the ‘greenest’ cars will cause more
pollution than many gas-guzzling off-roaders. In a list of the worst
polluting cars, some so-called environmentally friendly vehicles have been
highlighted as not so eco friendly.
findings strongly suggest that if we really want to help prevent global
warming we should reconsider the design of green vehicles and also reconsider
other policies. Carbon dioxide emissions which currently influence the way

‘green’ cars do push out less pollution when driven, the energy used
in building, transporting, servicing and scrapping these vehicles means
that, over their entire lift-cycle, they are likely to cause more

measured emitted CO2 by a range of cars and then added the
extra measurements for the vehicle’s whole-life cycle including creation
and depollution energy ratings.
Best-performing vehicle was the Jeep Wrangler off-roader with a whole-life
cycle energy cost of just 38p a mile. The Toyota Prius, was listed in 74th
place with a whole-life cycle energy rating of £2.03 while the Honda
Civic Hybrid, in 73rd place, cost £2.02 per mile and the Lexus
RX400h was placed 83rd out of the 96 cars surveyed.
The two-year investigation measured the environmental footprint of cars from their build, sell, drive and dispose of from initial concept to scrappage. Fuel efficiency is only a small part of the total energy used in a vehicle’s lifetime. CNW executive Art Spinella explained why hybrids show up so poorly - It’s because of their manufacture, replacement and disposal cost; items such as batteries, electric motors and lighter weight materials used in construction give off high emissions when created and again during depollution. Simpler vehicles use established technologies that need less energy in manufacture, life cycle and depollution.’ Although a modern hybrid uses less fuel and produces fewer tail-pipe emissions, it costs the environment significantly more in overall energy costs than most other cars.
Environmental spokesman for the Association of British Drivers, Ben Adams,
said ‘Politicians seem keener to make politically correct gestures than
to get the science right.’
Government car-user fleets have a sizeable quota of Honda Civic’s and
Prius Hybrids, some of which are used by ministers, which in the light of
this report this policy should now be reconsidered.

always there is a total failure in recognising other areas of pollution
such as fires, spillages and any likely increase in crash injury, human
pain and suffering as it falls outside the remit of the report. Moreover
this slant is destined to go unrecognised, even in the fullness of time,
unless post crash response, aftercare and rehabilitation becomes part of
