Abstract:Increasing concern over the potential harmful effects of greenhouse gas emissions has motivated the consideration of an aircraft CO2 certification requirement as one way to reduce aircraft CO2 emissions and mitigate the impact of aviation on climate. As a first step, there is the need to identify metrics that reflect CO2 emissions at the aircraft level. This report serves (1) to provide a summary of the ongoing study being funded by the U.S. Federal Aviation Administration (FAA) to generate and evaluate CO2 emissions metrics, and (2) to recommend, based on quantitative and qualitative analyses completed under the study thus far, the most promising CO2 frameworks consisting of metrics, correlating parameters (CP) and evaluation conditions for a potential aircraft CO2 certification requirement. A metric generally captures the key performance parameters intended to be influenced (and plotted on the y-axis a graph), a correlating parameter (captured on the x-axis of plots) is generally based on fundamental physical attributes of the aircraft, and evaluation conditions are conditions at which vehicle performance is measured and reported to show compliance.
