Another potential market for the use of ethanol is snowmobiles. Snowmobiles could provide a considerable market for ethanol in USA. There are a total of over 2.3 million snowmobiles registered in the United States. The snowmobile manu­facturers approve the use of ethanol blends of up to 10 %. The use of ethanol in snowmobiles greatly reduces emissions. In the USA, several million snowmobiles are registered. This is a significant factor to consider as a snowmobile with a con­ventional two-stroke engine emits 36 times more carbon monoxide and 98 times more hydrocarbons than an automobile. In fact, snowmobiles can create serious environmental and health risks that many national parks are considering limiting or banning the use of snowmobiles within the parks. Using a blend of 10 % etha­nol also eliminates the need for the use of gasoline antifreeze and removes and prevents deposit build up in the fuel tank (Launder 1999).
