However, the primary researcher, Paul D. Williams from the University of Reading in the UK, notes, "For reasons that are explained using a conceptual model, the eastbound shortening and westbound lengthening do not cancel out, causing round-trip journey times to increase."
As a result, even without any growth in air travel, his data suggests that aircraft will be flying for 2,000 more hours per year which means 7.2 million additional gallons of burned jet fuel and 154 million more pounds of carbon dioxide emissions.
