Aviation emissons set to rise: report

By Peter Woodman

Efforts to reduce aviation carbon dioxide (CO2) emissions will be outweighed by the growth in air passengers, according to new research.

Plane ticket prices would need to rise by at least 1.4% a year for emission levels to fall, the research by the University of Southampton said.

But such a rise would buck the recent trend of lower air fares, said the authors of the research.

They said that even if proposed mitigation measures were agreed upon and put into place, air traffic growth rates were likely to out-pace emission reductions, unless demand was substantially reduced.

The research's co-author, Professor John Preston, said: "There is little doubt that increasing demand for air travel will continue for the foreseeable future.

"As a result, civil aviation is going to become an increasingly significant contributor to greenhouse gas emissions."

The authors of the new study, which has been published in the journal Atmospheric Environment, have calculated that the ticket price increase necessary to drive down demand would value CO2 emissions at up to 100 times the amount of the current valuations.

"This would translate to a yearly 1.4% increase on ticket prices, breaking the trend of increasing lower airfares," said co-author and researcher Matt Grote.
