GREENAir travel accounts for 2% of global CO2 emissions, and that share is expected to rise to 12-27% by 2050. 40% of worldwide emissions are from short-haul flights. Electric aircraft are the solution. These planes have zero operational emissions, and the lowest infrastructural footprint of all modes of regional transport.

ACCESSIBLEWe believe air travel should be integrated into–not seperated from–our towns and communities. Our zero-emissions, low-noise aircraft can operate on 750m runways, making new use of the vast network of small airports close to city centres.

COST-EFFICIENTElectrification changes the equation for regional air travel. Electric aircraft are affordable to buy, operate and maintain. Simple, reliable electric motors reduce maintenance costs by 90% compared to turboprops, and intelligent electronic monitoring reduces inspection needs. Most importantly, fuel costs go down by 50-75%.
