<p>The European Union rejected a study that called bioenergy's climate benefits into question, saying that it failed to properly compare carbon savings to those of diesel and gasoline burned by cars. The report, by the <span>Scientific Committee of the European Environment Agency, said that biofuel and bioenergy targets are based on a "serious accounting error" and should be revised downward</span>.

<p>A National University of Singapore researcher said that pristine forests with the least disturbance sustain the highest biodiversity and are crucial to many tropical species. The study analyzed 28 tropical forests and found that regenerating and degraded forests had substantially lower levels of biodiversity than in forests untouched by humans. "There's no substitute for primary forests," the researcher said.

<p>China has increased requirements for its energy saving vehicle subsidy in an effort to curb fuel consumption and roll back stimulus measures. The government has been subsidizing fuel saving cars since June 2010, with additional subsidies for hybrid and electric cars in certain cities. However, the Ministry of Finance announced that cars would only be eligible for the 3,000 Yuan subsidy if they consume <span>6.3 liters of gas or less per 100 kilometers</span>, compared to the previous 6.9 liter standard.
