4Methodology All of ICAO’s environmental tools are: Developed or reviewed by the Council’s Committee on Aviation Environmental Protection (CAEP)Fully documented and use the best publicly-available dataSubject to continuous refinement and update
11ICAO Fuel Savings Estimations Tool Operational Measure Implementation (planned or post)+Need to quantify change in fuel consumption, but don’t have the tools?=USEIFSET
12ICAO Fuel Savings Estimations Tool (IFSET) Operational measures like PBN, CDO, CCO, RVSM etc. are among the measures from a basket of available measures that States are using today to reduce emissions.This was recognized in the last ICAO assembly and A37-19 requested ICAO to develop the necessary tools to assess the benefits associated with ATM improvements.States used sophisticated models or rules of thumb to estimate CO2 emissions savings from operational measures.IFSET bridges this gap by allowing those States without sophisticated models to estimate the savings in a harmonized manner.
13IFSET ICAO Fuel Savings Estimation Tool Simple to use. Scientific defendable based on pre computed data from the US FAA’s AEDT model.Consistent with Global Air Navigation Plan.Minimal data requirements.
14ICAO Fuel Savings Estimations Tool (IFSET) How it Works? Fleet mix defined for baseline and post-implementation scenarioAircraft type group“Remaining flight distance”(as a surrogate for weight)User selects “elements” to define baseline and “new”procedure. [Taxi/Climb/Level/ Descend]Tool estimates the change in total fuel consumption between the two scenarios
15States’ Benefits from IFSET States can quantify savings from planned or implemented measures.States can prioritize and select potential measures.States can generate business cases from IFSET results.Facilitates States in raising funding for selected measures.States can implement measures that reduce emissions from aviation.(Today States in every Region and also ANSP’s are using IFSET to quantify and report reduction in emissions from operational measures)
