They do have a solution. A Bipartisan Group of US Senators Calls on EPA to Refrain From Including Indirect Land Use Change in Biofuel Regulations
17 March 2009 A bipartisan group of 12 US senators led by Tom Harkin (D-IA) and Chuck Grassley (R-IA) has called on the Environmental Protection Agency (EPA) not to include calculations of indirect land use change (ILUC) effects as contributors to life-cycle greenhouse gas (GHG) emissions for biofuels in the upcoming rulemaking for implementation of the updated Renewable Fuels Standard (RFS-2) enacted in the Energy Independence and Security Act (EISA) of 2007.
The Renewable Fuel Standard (RFS-2) defined within the Energy Independence and Security Act of 2007 requires biofuels to meet specified life-cycle greenhouse gas emission reduction targets to qualify. The law specifies that life-cycle GHG emissions are to include direct emissions and significant indirect emissions such as significant emissions from land use changes, as determined by the Administrator.
Depending upon the assumptions and boundary conditions set in the ILUC evaluation, the result can dramatically increase the calculated GHG footprint of a biofuel, far offsetting the presumed greenhouse gas benefits of its use.

The real answer is to get the FedGov out of the business of regulating so-called greenhouse gases.
Bipartisan Dishonest Accounting FOR GWG reference bump - fraud + more fraud = ? A: One big fraud. Sheeesh.
