Three Midwest senators have introduced legislation that would prevent EPA from penalizing U.S. corn and soybean growers for land use changes or potential land clearing for increased biofuel production in other countries.

Sens. Tom Harkin and Charles Grassley of Iowa and Ben Nelson of Nebraska said EPA’s proposed rulemaking for implementing the so-called Renewable Fuel Standard 2 or RFS2 would limit the U.S. production and use of biofuels required in the energy bill passed by Congress in 2007.

Their legislation, a proposed amendment to the Senate Interior-Environment Appropriations bill would prohibit the EPA, for one year, from spending funds to include international indirect land use change emissions in the implementation of the RFS.

In its proposed rule issued last spring, EPA said ethanol and biodiesel producers must meet higher greenhouse gas emission standards than those for petroleum-based fuels because of the potential for increased GHG emissions from land-clearing for increased corn and soybean plantings in the U.S. and other countries.

“At this time, the data and analytic methodologies for credibly calculating international indirect land use change emissions do not exist,” the senators said in a statement. “Because of this, including these international emissions in the EPA’s rule would put an unjust burden on the biofuels industry.”

“Expanding the production and use of domestic biofuels is one of the most critical components of our strategy for reducing dependence on imported oil,” said Harkin, a Democrat and former chairman of the Senate Agriculture Committee.

“The Renewable Fuel Standard, as revised in 2007, lays out a sound expansion trajectory. To meet our strategic goals, we must stay on that path. We have broad, solid agreement about which direct emissions should be included in lifecycle greenhouse gas emissions, and we have broad agreement on how to quantify those emissions.”

The 2007 energy bill, however, calls for the inclusion of indirect emissions, such as those associated with land use changes, he noted. “This is a mistake. To put it bluntly, including international indirect emissions at this time is bad policy.”

“Biofuels are an important part of the diverse energy mix that will reduce our dependence on foreign sources of energy,” said Nelson. “This amendment will stop the EPA from using inaccurate or incomplete calculations that could compromise our ability to expand production of biofuels. More complete studies need to be conducted before land use calculations can be effective.”
