News Summary: Ethanol debate heats up

Too much ethanol in gas? High-blend fuel prompts debate; are older cars, motorcycles at risk?

DISMISSED: On Monday, the Supreme Court rejected a challenge by the American Petroleum Institute, the oil industry's chief lobbying group, to block sales of the high-ethanol blend of gasoline known as E15. The justices left in place a federal appeals court ruling that dismissed challenges by the oil industry group and trade associations representing food producers, restaurants and others. The API had argued that E15 was dangerous for older cars.

YES, ETHANOL!: The Environmental Protection Agency has proposed a 16.5 billion-gallon production requirement for ethanol and other gasoline alternatives this year, up from 15.2 billion gallons last year. By 2022, the law calls for more than double that amount. Biofuel advocates and supporters in Congress say the law has helped create more than 400,000 jobs, revitalized rural economies and helped lower foreign oil imports by more than 30 percent while reducing emissions of carbon dioxide and other greenhouse gases.

NO, ETHANOL!: the oil industry, refiners and some environmental groups say the standard imposes an unnecessary economic burden on consumers. Using automotive fuel that comes from corn also has significant consequences for agriculture, putting upward pressure on food prices, critics say.
