Thanks to an obscure tax provision, the United States government stands to pay out as much as $8 billion this year to the ten largest paper companies. And get this: even though the money comes from a transportation bill whose manifest intent was to reduce dependence on fossil fuel, paper mills are adding diesel fuel to a process that requires none in order to qualify for the tax credit. In other words, we are paying the industry--handsomely--to use more fossil fuel.

In 2005 Congress passed, and George W. Bush signed, the $244 billion transportation bill. It included a variety of tax credits for alternative fuels such as ethanol and biomass. But it also included a fifty-cent-a-gallon credit for the use of fuel mixtures that combined "alternative fuel" with a "taxable fuel" such as diesel or gasoline.

By adding diesel fuel to the black liquor, paper companies produce a mixture that qualifies for the mixed-fuel tax credit, allowing them to burn "black liquor into gold,"
