Environmentalists and auto manufacturers worried about E10 in Mexico

In Mexico, despite the opportunities to export more ethanol from the Midwest in response to the new 10% ethanol-blending mandate, local environmentalists are concerned that increased ethanol blending will boost the amount of ozone in the air along with other challenges such as the greenhouse gases associated with the production of ethanol. They are especially concerned about high altitude cities, though the US Grains Council assures that other high altitude cities such as Denver and Bogota have found E10 to not increase ozone levels. The Mexican auto manufacturers’ association are also concerned that the older vehicle fleet compared to the US will cause challenges at the pump with more vehicles not able to use higher blends.
