No surprise for anyone paying attention.

A study published in late April by an environmental group found that Europe’s biofuel regulations created 80 percent more carbon dioxide (CO2) emissions than the conventional oil they replaced. The report estimates the biofuels create new emissions equivalent to putting an extra 12 million cars on the road.

Europe has been blending small percentages of biofuels into conventional gasoline and oil and diesel specifically to reduce CO2 emissions. The continent plans to require biofuels account for 10 percent of all fuel used by 2020. The EU’s CO2 emissions are estimated to have increased by 0.7 percent last year relative to 2014, even though the continent has spent an estimated $1.2 trillion financially supporting green and bio-energy with the goal of lowering CO2 emissions.
