Representative Bill Flores (R-TX) offered an amendment to H.R. 2397, the Department of Defense Appropriations Act, 2014, which would defund the federal government’s prohibition on using unconventional transportation fuels that emit more greenhouse gases than traditional fuels. The amendment would prohibit the use of funds in the bill to enforce Section 526 of the Energy Independence and Security Act of 2007, which specifically prohibits federal agencies from buying transportation fuels from unconventional sources like coal-to-liquid, oil sands, and oil shale, unless the contract specifies that the lifecycle greenhouse gas emissions do not exceed those produced by conventional petroleum. The Defense Department has said that it supports Section 526 as part of an effort to decrease its reliance on fossil fuels, and that Section 526 has not prevented the Department from meeting current mission needs. On July 23, the House approved the Flores amendment by a vote of 237-189 (House roll call vote 394). NO IS THE PRO-ENVIRONMENT VOTE. The Flores amendment was not included in the FY14 omnibus funding bill signed into law by President Obama on January 17, 2014.
