Prove What's Possible in Zero-Carbon Flight
The Freedom Flight Prize challenges innovators worldwide to deliver a zero-carbon, 100+ seat aircraft capable of transatlantic flight and return within 24 hours. Step forward as an entrant or sponsor and help redefine aviation.
Make your mark on aviation history
Fly a zero carbon emission 100+ seat passenger aircraft between London and New York and complete the return trip within 24 hours.
Entrants will be judged on the speed of their aircraft, the number of passengers carried, and the amount of energy used to complete the challenge.
Predicted Timeline
Time is of the essence
As the world adapts to the new normal, the climate emergency urgently needs addressing to avert an even bigger global disaster. Flight numbers will return to normal levels, adding to global carbon emissions.
Aviation caused just under 1 billion tonnes of CO2 emissions in 2019, yet it remains central to business, trade, culture, education, and travel. The Freedom Flight Prize exists because truly zero carbon renewable flight technologies are within reach.
