Does Oil Cause Indirect Land Use Change?

I’ve been paying a lot of attention recently to new analyses attempting to model carbon emissions from indirect land use change, which is the conversion of land needed to maintain an international balance of supply and demand for agricultural crops, an effect that is heavily determined by crop prices. These new analyses raise a question about the existing assumption that oil has zero effect on land use change. Tim Searchinger, the lead author of one Read More >

More Models to Measure Land Use Change

As the U.S. EPA and California’s Air Resource Board seek to implement their respective Renewable and Low-Carbon Fuel Standards, economists continue to refine models to measure and predict indirect land use change emissions associated with biofuels. Many of the original critiques of the Searchinger paper in Science that initiated this debate commented on the uncertainty in attributing indirect land use change to biofuels. Prof. Roger Sylvester-Bradley of ADAS UK Ltd., for instance, summarizes many of Read More >

EPA Denies Texas Request to Waive RFS

Today, EPA Administrator Stephen Johnson announced the decision to deny Texas Gov. Rick Perry’s request for a waiver of the Renewable Fuel Standard. Johnson said in a press release: “After reviewing the facts, it was clear this request did not meet the criteria in the law. The RFS remains an important tool in our ongoing efforts to reduce America’s greenhouse gas emissions and lessen our dependence on foreign oil, in aggressive yet practical ways.” In Read More >

More Biofuels Bashing

Exactly a month ago, Roll Call newspaper revealed that the Grocery Manufacturers Association had launched a PR campaign to roll back U.S. biofuel policy. GMA is once again on the offensive, releasing an industry-funded study that blames biofuels for higher food prices, ignoring the rapid increase in the price of oil that is driving up the costs of agricultural production and increasing demand for alternatives. Kraft Foods sponsored the recent study by Keith Collins, Ph.D., Read More >
