Aviation Fuel & Emissions Calculators
Free, practical calculators for the numbers behind cleaner flight — jet-fuel CO2, SAF savings, flight fuel burn, fuel energy content, hydrogen and battery range, and fuel cost per flight. Educational tools, not certified performance or emissions data.
Aviation Energy Reference
Energy density by fuel, CO₂ per passenger by aircraft class, SAF blend savings, and range from the same mass of each carrier.
Jet Fuel CO2 Emissions Calculator
Turn a quantity of jet fuel, in kilograms or litres, into the CO2 it releases when burned, using the standard 3.16 kg of CO2 per kg of Jet A
SAF Blend & CO2 Savings Calculator
See how much lifecycle CO2e a sustainable aviation fuel blend saves versus conventional Jet A, from the blend percentage and its lifecycle reduction
Flight Fuel Burn Calculator
Estimate fuel burned from distance and aircraft class — regional, narrowbody, or widebody — with total fuel, litres, CO2, and an optional per-passenger split
Fuel Energy Content Comparison Calculator
Compare Jet A, SAF, liquid hydrogen, and batteries by energy per kilogram and per litre, and see why hydrogen and batteries behave so differently
Hydrogen / Battery Aviation Range Calculator
Estimate flight range for jet fuel, hydrogen, and batteries from the same on-board mass, once each drivetrain's efficiency is taken into account
Fuel Cost per Flight Calculator
Turn a fuel quantity and a unit price into the fuel bill for a flight, in litres, US gallons, or kilograms, with an optional cost per seat
