this exact amendment, introduced by mr. boren of oklahoma last year, passed the house by voice vote, unfortunately not ato wanted by the senate. this language preserves the intent of section 526 without tying the hands of federal agencies that need to procure fuel. without using carbon capture and sequestration, it produces twice as much greenhouse gas emission as conventional petroleum fuel and fuel from tar sands. generates 14% to 42% more greenhouse gas emissions. section 526 is successfully protected taxpayers from costly and destructive subsidies of highly polluting fuel production. the reality is that fuel derived from tar sands comprise a small portion consumers purchase. mr. chairman, this amendment simply clarifies that the hands of the federal government are not tied and federal agencies can in fact procure commercially available fuel
