The Ministry of Environment has issued a ranking of more polluting cars sold in the country. Although they considered a cleaner fuel, the alcohol cars occupy eight of the 15 worst locations - some have engine "flex".
"Our intention is that the consumer also takes into account the emissions of pollutants," said Minister Carlos Minc (Environment).
250 assessments were made of light vehicles produced in 2008-cars "flex", which represent 85% of the fleet sold in this country in 2008, had two different ratings, one for gasoline and one for alcohol.
Notes were given one (worst) to ten (best) to issue three polluting gases - carbon monoxide, hydrocarbons and nitrogen oxides - which have no effect on global warming, but affect health.
These notes, called green, do not take into account the emission of carbon dioxide - CO2, the main gas causing the greenhouse effect.
The ranking of the greenbacks, the best performance was 2.0 Focus of Ford's gasoline-powered, with note 9.4. The worst performance was the Corsa 1.4, Chevrolet, when running on gasoline. Only eight cars were scored higher than nine, leading the list of the cleanest.
The notes were based on information collected during the licensing of vehicles. All models evaluated observe, therefore, the maximum emission limits adopted in the country in 2008. In January, these limits become more stringent. New limits will take effect in 2014.
Dioxide
The ministry also attributed score (called red notes) for the emission of CO2 (on a scale of five to ten). These notes, however, did not enter the calculation for the creation of the ranking of the most polluting because they were given only to gasoline vehicles.
This is because the government considers, following an international focus, the production of ethanol from sugar cane capture carbon from the atmosphere, zeroing the emission of carbon dioxide.
When combined ranking position (greenback) at the level of carbon dioxide emissions (note red), the worst performer was the Ford Ranger XL 2.3.

Also available are data on fuel consumption organized by Inmetro (National Institute of Metrology, Standardization and Industrial Quality).
