FLAPS.25
what is it?
Aviation Emissions model
FLAPS.25 is an emissions model developed specifically for aviation. The model allows airports, airlines and governments to monitor, benchmark and predict their emissions. The model can also be used to assess the effectiveness of technical and operational measures to reduce emissions.
all emissions for all aircraft
Complete
FLAPS.25 distinguishes 25 different types of emissions, including CO2, NOx, SOx, VOC, HC en CO. The model supports all common aircraft and engine types, from the smallest single-engine aircraft to the largest jet aircraft. Unlike most other emissions models, FLAPS.25 also estimates emissions from Auxiliary Power Units (APUs). This allows or a complete estimation of aircraft emissions for an airport, airline or country.
latest insights and data
Advanced
FLAPS.25 is an advanced emissions model based on ICAO recommendations. The model uses a bottom-up approach, estimating emissions for each individual flight and flight phase separately based on aircraft and engine type, flight distance and operational procedures at departure and arrival airports (thrust settings, cab times, APU usage and so on). This is important as emissions vary by engine type, flight phase and procedures used. The emissions are then aggregated to the level of an airport, airline or country.
FLAPS.25 combines actual flight data with the latest aircraft engine emission data from ICAO, FOCA, the FAA for an accurate estimate.
limited data needs
Flexible
FLAPS.25 is a flexible model and therefore suitable for all airports and airlines. The model uses actual flight data, such as the aircraft and engine type used, the distance flown and the operational procedures applied at origin and destination (thrust settings, cab times, APU usage and so on). When certain data are not available, the model uses airport or industry averages. This always provides the most accurate estimate of emissions given the available data.
for airports, airlines and governments
Applications
FLAPS.25 is used for airports, airlines and governments for the purpose of:
Monitoring
Monitoring aviation emissions allows stakeholders to keep track of emission reduction targets. If it turns out that emissions decrease slower than anticipated, additional measures can be taken to achieve the targets. Monitoring emissions over time also shows how effective previous measures, such as fleet renewal and operational improvements, have been.
Benchmarking
Benchmarking aviation emissions shows how an airport, airline or country is performing compared to their peers. Based on this, lessons can be learned on how to further reduce emissions.
Prediction
Future aviation emissions depend on developments in traffic, fleet renewal, use of sustainable fuels (SAF) and operational changes. Predicting future aviation emissions based on such developments, allows stakeholders to determine whether emissions remain within acceptable limits.
Scenario studies
Scenario studies provide insight into the effectiveness of various measures to reduce emissions. This involves examining the extent to which each measure contributes to emission reduction. Examples of measures for which the effectiveness can be assessed are: fleet renewal, use of sustainable fuels (SAF), alternative thrust settings, single-engine taxiing, limiting APU use and so on.
