Arguing over the pros and cons of using ethanol as a transportation fuel isn't just an American thing. The Brazilians are going at it, too. We will translate.

A recent report from Nature Geoscience suggested that using more ethanol in light-duty vehicle transportation increases local smog levels. Now,, citing the Air Pollution Laboratory at São Paulo University's Faculty of Medicine, is calling that report a bunch of methane-producing cow manure.

The findings from the prior report stemmed from a misinterpretation of ozone information and the disregarding of actual air-quality data in Sao Paulo, says, not-so-sweetly calling the Nature Geoscience study "misleading at best."

The newer analysis says that replacing gasoline and diesel with sugarcane-based ethanol prevents more than 850 deaths and 12,000 hospital admissions in Brazil annually. In fact, the country may save as much as $190 million a year in medical costs because of sugarcane-based biofuel use. Additionally, greenhouse gas emissions would be about 30 percent worse than they are now if not for the use of ethanol and the 2003 introduction of flex-fuel vehicles to the Brazilian public. And that difference grows as the country's vehicle use increases.

      This is like the tobacco industry telling you that cigarettes are not bad for you.

      Ethanol is the worst thing to happen to fuel. #1 It is now found to cause more air pollution in it's whole cycle than oil based fuel. #2 Farmers are converting natural spaces into corn fields to grow more corn. #3 Those corn fields are usually next to waterways which are now being polluted with fertilizer and pesticide runoff. #4 The price of corn based food has gone up and that affects the poorest among us. #5 Ethanol causes equipment to run poorly. #6 Ethanol causes fuel systems to need plastic and rubber pieces replaced and carburetors to be rebuilt more frequently due to the alcohol. #7 Ethanol has less energy so engines need to work harder. #8 Ethanol burns hotter which causes marginal engines to overheat. Need I say more? Ethanol was a horrible government decision fro the US.

      SugarCanes made with solar power (Sun Energy) and some other. We make petrolium out of sugarcane. Car burns petrolium and produce CO2 and other unhealthy gases. Why not use that space for Solar Panels and run EV instaed?

      Did Brazil cut trees to make room for producing ethanol producing fields? Or how do they otherwise factor in that issue?

        @Luc K
        Did American farmers cut trees to grow stuff ? like corn for ethanol

      Hmmmm... is defending sugar-derived ethanol against the rather obviously named oil/gas advocates at blah blah blah Geoscience. I am SHOCKED at their respective positions. Shocked, I tell you!

      Look at the players and who is saying what. On one side, Nature Geoscience says its bad. On the other side, says it's good. Now, which one has money to loose and feels threatened? You've just found the one with the higher probability of spreading misinformation and outright lies. Congratulations.
