While at least three commercial supersonic aircraft projects are underway, a study by the International Council on Clean Transportation issues a warning on the negative impact on harmful emissions and pollution
Scientists issue a warning against the return of supersonic flights, put off with the retirement of Concorde . In a new study on the environmental impact of supersonic commercial aircraft they consider that these will cause an exponential increase in emissions of Generalities

Although aviation enthusiasts and regular travelers see eye favorable the arrival of new-generation aircraft capable of halving the duration flights, scientists from the International Council on Clean Transportation (International Council for Clean Transportation) warn that commercial supersonic devices that are under construction, capable of reaching twice the speed of the his … "data-image =" https://www.cdn.v5.futura-sciences.com/buildsv6/images/midioriginal/3/c/e/3cf19836ed_97948_speed-son.jpg "data-url =" / sciences / definitions / physics-speed-sound-16089 / "data-more =" Read more "> speed of sound or Mach 2, would be unlikely to meet current standards in organic matter, nitrogenous matter , etc.

Five to seven times more fuel per pbadenger [19659006] Compared to the limits for subsonic aircraft, for example, supersonic aircraft could exceed the emissions of nitrogen oxides by 40% and those of carbon dioxide by 70%. %. Disturbing figures. In other words, supersonic aircraft could burn five to seven times more fuel per pbadenger than conventional subsonic aircraft. In addition, according to scientists, these new aircraft may not be able to meet anti-noise standards during landing and take-off.
These results are troubling because the aeronautical sector is already One of the leaders of the emissions of To understand the global warming, it is necessary to understand its link with the natural phenomenon of … "data-image =" https://fr.cdn.v5.futura-sciences.com/buildsv6 /images/midioriginal/b/9/e/b9f0872ae1_50084221_ges2011-poilaumenton-flickr-01.jpg "data-url =" / planet / definitions / climatology-gas-greenhouse-effect-5381 / "data-more =" Read more "> The fastest-growing greenhouse gas says the study, aircraft produce about 3% of global carbon dioxide emissions, and 11% of CO emissions 2 of the entire transport sector
Three supersonic aircraft projects to succeed the Concorde [19659006] In 2015, aviation was responsible for about 800 million tonnes of CO 2 emissions as much as the German economic sector as a whole. If the current trend continues, the International Civil Aviation Organization predicts that CO 2 emissions from the international aviation sector will triple between 2018 and 2050.
Currently, three airlines are working to revive supersonic flights after the Concorde retreat, in 2003. This is Lockheed Martin of Boom (a Start-up, digital and biotechnology
