CHOLESTER-OIL.

Rep. Lloyd Doggett's new piece of legislation preventing ConocoPhillips from claiming a renewable diesel tax credit has 50 cosponsors so far. At a press conference this afternoon, he introduced the bill -- which he's calling the "Responsible Renewable Energy Tax Credit Act of 2007" -- and also coined the term "cholester-oil" to refer to the part-animal-fat fuel. As I suggested in my piece this morning, one major concern surrounding Conoco's "renewable diesel" is that the company bypassed an EPA fuel certification process by claiming the fuel is "chemically equivalent to diesel." "There are technical concerns," National Biodiesel Board Chairman Joe Jobe said at the conference, " You can't claim on one hand that the product is chemically equivalent to diesel to avoid the EPA on one hand and then claim [emissions] benefits beyond standard diesel on the other."
