Biofuels Increase Air Pollution and Reduce Crop Yield, New Study Says

This is the conclusion that a team from Lancaster University, England, reported in the journal Nature Climate Change.

The researchers looked into the impact of producing more biofuels as part of the scheme adopted by EU to tackle climate change.

The trees grown to produce fuel such as Poplar, Willow or Eucalyptus, reduce the concentrations of carbon dioxide in the atmosphere, but they were found to release the chemical isoprene into the air, which reacts with other pollutants to produce ozone and could cause up to 1,400 premature deaths in Europe by 2020.

According to Nick Hewitt, the lead author of the publication, this study shows a real danger for humans and crop yields. The findings are innovative and present something that has not been considered before.

The team estimated that by 2020, in addition to the predicted premature deaths, and in their attempt to produce more biofuels, EU might suffer a great reduction in annual value of wheat and maize.

The study suggested that if the biofuel plantations are located away from polluted hotspots, this might limit the formation of ozone. The authors also suggest the use of genetic engineering to minimize the isoprene emissions.

The authors did not compare the impact of isoprene emissions with gas, oil and coal emissions. As Hewitt pointed out, it is exactly the emissions from fossil fuel burning that made EU and UN turn to biofuels.

  1. Gorilla Glass effectively reduces screen parallax and improves touch control
    accuracy to provide better visual quality. The parallax of 5.0mm soda lime
    glass is 2mm when viewed at an angle of 25 degrees. The parallax is 4mm at
    angle of 45 degrees and it increases to higher than 10mm at 75 degrees. But the
    parallax of 0.7mm Gorilla Glass is lower than 1mm and increases only slightly
    when viewed at an angle of 75 degrees.
