(Newser) – Bad news on the climate-change front: Airplanes are emitting 20% more carbon dioxide than anyone thought. According to a newly disclosed report, they could release 1.5 billion tons a year by 2025—compared to 3.1 billion tons a year now released by all the citizens of the EU, reports Wired. The study also predicted growing airplane noise pollution.

"Growth of CO2 emissions on this scale will comfortably outstrip any gains made by improved technology and ensure aviation is an even larger contributor to global warming by 2025 than previously thought," said a rep from an environmental group. "Governments must take action to put a cap on air transport's unrestrained growth."
