American Airlines and Google were able to cut contrails made by jets by more than half during a small trial, a move that could significantly reduce the global-warming footprint of the travel industry, but with a slight increase to fuel use.

    So does a 54% reduction in trails offset the 2% higher carbon emissions?

      Probably hard to measure as the contrails stay in the atmosphere for hours and the CO2 stays there for what, hundreds or thousands of years?
