Alternative Fuels May Boost Pollution

ABC Science Online:
Some alternative vehicle fuels such as liquid coal can cause more harmful greenhouse gas emissions than polluters such as petrol or diesel, scientists warned in a US study.
“Liquid coal, for example, can produce 80% more global warming pollution than gasoline,” said the Union of Concerned Scientists, a non-profit environmental group, in a statement introducing its study.
Liquid coal is viewed as a potential replacement to the oil on which countries rely heavily to fuel vehicles.
“Corn ethanol, conversely, could be either more polluting or less than gasoline depending on how the corn is grown and the ethanol is produced,” the report said.
The analysis was based on replacing a fifth of all gasoline consumed in the United States with alternative fuels by 2030.
If most of these alternatives consist of liquid coal, the change could pump pollution into the atmosphere equivalent to 34 million more cars on the road.
