Story summary

Researchers at the University of Surrey introduced the Air Travel Passenger Dynamic Emissions Calculator (ATP-DEC).
ATP-DEC shows current carbon calculators underestimate air travel's climate impact, sometimes by more than twice.
The calculator accounts for CO2 and warming effects like nitrogen oxides and contrails.
The calculator uses real-world flight data and includes upstream emissions.
Benchmark tests align with post-flight data, and integration into airline systems is possible immediately.
