Reinvent Flying for a Greener Future

We cannot escape nature and nature cannot escape us.
The future holds many surprises but climate change and demand for air travel will not disappear in upcoming decades. Human curiosity paired with lower flight costs promise this.
It’s easy to forget flights come at a huge carbon cost. A round trip flight from England to Australia emits as much CO2 as driving your car for an entire year.
But cleaner jet fuels are available now to make your flight less harmful.

Why Flightnook?

Cleaner jet fuels are the fastest way to make travel more sustainable.
Your premium payment buys clean jet fuel made from biomass waste. The feedstock you purchase through us is sourced sustainably and safeguards the environment. Importantly, we do not support feedstock that competes with food and feed.
Flightnook uses local production models. This means the clean jet fuels you purchase will likely not fuel your flight. Instead, we keep carbon impact low by choosing to transport this clean jet fuel to the airport closest to the production facility.
Though the fuel doesn’t go to your flight you’re supporting green energy and making a clear statement to industry. The result is the same, your fuel is just used in another airplane.
We send you information accounting for how the clean jet fuel was produced, what airline travelled on it, and what your support for green energy impacts.
Sustainability is hard to measure, that’s why transparency is one of our highest priorities.

Cleaner Jet Fuel Life Cycle Assessment

Flight requires fuel because other forms of energy storage, like batteries, are too heavy.
But renewable resources like biomass waste, house trash, and waste gases produce clean jet fuels that power airplanes just as well as current kerosene, a fossil fuel. In the near future we will also be able to convert renewable electricity and algae into clean jet fuel.
Clean jet fuels emit up to 80% less CO2 emissions measured on a lifecycle assessment.
This means converting biomass waste into clean jet fuel has a much lower carbon impact than extracting fossil fuels through fracking or deep-water drilling.
Clean jet fuels do not count combustion as a stage in their lifecycle because once burned they feed back into the lifecycle loop. The CO2 they produce in-flight are considered equal to the CO2 needed to grow feedstock plants, which use CO2 for photosynthesis.

Through Flightnook you purchase pure clean jet fuel. Once mixed with conventional jet fuel we refer to it as cleaner jet fuel.
Conventional jet fuel harms our planet through CO2 emissions and radiative forcing, an effect describing sunlight reflections. But cleaner jet fuel burns cleaner so it cuts CO2 emissions and radiative forcing.
Plus, unlike fossil resources, biomass waste will not run out.

Environmental Integrity

All clean jet fuel accessed through Flightnook are certified to ensure compliance with high environmental and equitable standards.
First fossil fuel substitutes vs. cleaner jet fuel
  • Clean jet fuel feedstock doesn’t interfere with local food and feed producers
  • No land with high carbon stock has been harmed
  • Life cycle assessment confirms sufficient level of greenhouse gas emissions savings
Other certifications also include additional sustainability checks like soil, water, air protection, and social criteria. Besides environmental certificates, technical certificates are also required to secure safe operations. For more information visit FAQ.

Technical Possibilities and Constraints

All clean jet fuels through Flightnook are ‘drop-in’ fuels which means they share properties with conventional jet fuel and can be used without airplane modifications.
The highest certified fuel mix for commercial flights is currently 50% clean jet fuels.
Our *upcoming* calculator enables you to estimate your CO2 emissions per flight! We’re working hard to get it to you ASAP.
Flightnook is committed to purchasing clean jet fuels that have the greatest emissions saving capacity. This depends on the availability of raw materials, the processes they go through to be airplane-ready, and the distance from the production facility to the airport.
We only buy from clean jet fuel providers that have potential to cut CO2 emissions to a minimum of 50%, see FAQ for certification details.

Why isn’t this happening already?

Some commercial flights have been powered by cleaner jet fuels but since these greener fuels are twice as expensive as fossil based fuels, they aren’t widely used.

International and domestic regulations aren’t changing fast enough to encourage a switch to cleaner jet fuels to keep pace with our impending climate reality.
