There’s a raging controversy in Brazil about the use of natural ethanol as an additive in motor fuels. The debate has been given extra sharpness lately by the proposal to increase the ethanol content in gasoline (petrol) from twenty-five percent to 27.5%.

On the one hand the Cane Sugar Industry Union (UNICA) claimed the move will have no ill effects and will even benefit engines, the economy and the environment generally while reducing Brazil’s need for imported petroleum.

On the other hand, ANFAVIA, the Motor Manufacturers’ Group say that the extra ethanol will damage both engines and the environment and therefore the petroleum percentage ought to be maintained.

The issue is being evaluated by the Ministry of Energy but a final decision is not expected soon.
