Small Changes to Routings Could Effect Big Environment Changes
Adjusting the altitudes of 50 flights could reduce impact by 50%
Contrail

Small altitude adjustments on business aviation flights could make a big difference in the environmental impacts of contrails—the condensation trails of aircraft—without CO2 emission tradeoffs. That's the assessment of a just-concluded environmental study conducted by aviation sustainability company 4Air has found that 

The study, conducted over one year, encompassed 16,000 flights and more than 27,000 flight hours. It found that adjustments on even 50 flights out of 16,888 would have reduced the non-CO2 emission impact from the sample by more than 50%.
