Scientists warn that the return of supersonic air travel, which was shelved with the retirement of the Concorde, will result in exponential carbon emissions and noise pollution in a new study that takes a closer look at the environmental impact of commercial supersonic jets. 

Though aviation enthusiasts and frequent flyers may be looking forward to the next-generation aircraft which could cut flying times by as much as half, scientists at the International Council of Clean Transportation warn that commercial supersonic jets that are being built today are unlikely to comply with existing flying standards. 

When set against limits currently in place for subsonic planes, for instance, supersonic aircrafts are estimated to exceed limits for nitrogen oxides by 40 percent and carbon dioxide by a worrisome 70 percent. 

Put another way, supersonic jets could burn five to seven times as much fuel per passenger compared to regular subsonic planes.
