A study by researchers at the University of Sao Paulo, Brazil, has found that ethanol can be a viable alternative to gasoline for vehicles, and at the same time, its use can effectively reduce emissions. Brazil is one of the world’s largest producers of sugarcane, and cane-based ethanol. Researchers found that the ethanol provides nearly eight times the energy used to create it, and that number could increase further with the introduction of new technologies and plant varieties.
The study considered that cane plantation would not involve felling any native forests, and without any deforestation involved, cane ethanol could help Brazil achieve its reduced emission targets. By 2020, Brazil plans to reduce emissions in the transport sector by 43 percent, and 18 percent for overall emissions, not factoring emissions by deforestation.
Since Brazil has a fairly large quantity of the raw material (sugarcane) required for the ethanol, and the country has already taken concrete steps in the right direction, it seems very much possible that Brazil will achieve its targets.
