Do biofuel policies seek to cut emissions by cutting food?

A study published today in the journal Science found that government biofuel policies rely on reductions in food consumption to generate greenhouse gas savings. Shrinking the amount of food that people and livestock eat decreases the amount of carbon dioxide that they breathe out or excrete as waste. The reduction in food available for consumption, rather than any inherent fuel efficiency, drives the decline in carbon dioxide emissions in government models, the researchers found. "Without reduced food consumption, each of the models would estimate that biofuels generate more emissions than gasoline," said Timothy Searchinger, first author on the paper and a research scholar at Princeton University's Woodrow Wilson School of Public and International Affairs and the Program in Science, Technology, and Environmental Policy. The study looked at three models used by U.S. and European agencies, and found that all three estimate that some of the crops diverted from food to biofuels are not replaced by planting crops elsewhere. About 20 percent to 50 percent of the net calories diverted to make ethanol are not replaced through the planting of additional crops, the study found. Both the models used by the U.S. Environmental Protection Agency and the California Air Resources Board indicate that ethanol made from corn and wheat generates modestly fewer emissions than gasoline. The fact that these lowered emissions come from reductions in food production is buried in the methodology and not explicitly stated, the study found. The European Commission's model found an even greater reduction in emissions. It includes reductions in both quantity and overall food quality due to the replacement of oils and vegetables by corn and wheat, which are of lesser nutritional value. "Without these reductions in food quantity and quality, the [European] model would estimate that wheat ethanol generates 46% higher emissions than gasoline and corn ethanol 68% higher emissions," Searching said...more

Governments would actually deceive us to justify their political agenda?

And we're the lucky ones who pay the salaries of these modelers, who pay for the subsidies going to the biofuels industry and who pay more at the pump for fuel.  Say "thank you" to the DC Deep Thinkers in both political parties.
