Airplanes dirtier than previously thought

How much dirtier, in terms of carbon dioxide emissions? About 20 percent worse:
An unpublished study by the world’s leading experts has revealed that airlines are pumping 20 per cent more carbon dioxide into the atmosphere than estimates suggest, with total emissions set to reach between 1.2 billion and 1.5 billion tonnes annually by 2025.

The report, by four government-funded research bodies, is one of the most authoritative estimates of the growth of pollutants produced by the industry. It was presented to a conference co-organised by the United States’ Federal Aviation Authority but not given a wider audience.

And, that’s not all.

The four bodies estimate aviation-caused CO2 will more than double by 2025.
