No-frills carriers leave a softer "carbon footprint" in comparison to full-service airlines owing to their newer fleets, higher densities of seats and direct flights, a new study has claimed.
According to an analysis by Liligo.co.uk, a UKbased flight-comparison website, No-frills carriers produce at least 35 per cent of the carbon emissions per passenger than the full-service airlines.
The team observed that a couple flying with Ryanair (No-frills carrier) from London to Venice and returning a week later have a carbon footprint of 410 kg, while the equivalent journey on Alitalia -- full-service airlines -- would produce 977 kg of carbon footprint.
Similarly, a flight from London to Zurich with easyJet has a carbon footprint of 277 kg per couple, compared with 688 kg with Aer Lingus, the Telegraph reported.
"Our analysis shows that the environmental stigma of budget travel may be unwarranted," said Gbenga Kogbe of Liligo.co.uk.
"Travellers can now assess financial and environmental costs of travelling with low-cost airlines, traditional airlines and charter-flight companies," Kogbe added.
