To mitigate aviation CO 2 emissions, the International Civil Aviation Organization’s Committee on Aviation Environmental Protection is considering an aircraft CO 2 emissions certification requirement. This paper presents an evaluation of potential CO 2 metric systems for their suitability as a basis for an aircraft CO 2 certification requirement. Candidate CO 2 metric systems, consisting of a metric, a correlating parameter, evaluation conditions, and a notional limit line are assessed against a set of key criteria. The metric systems were chosen to reflect aircraft fuel consumption, which directly correlates with CO 2 emissions for a given fuel type. Key criteria were identified to represent desirable attributes of the metric system, that is the ability to represent fuel efficiency performance improvements, validity across a range of aircraft types, correlation with fuel efficiency in actual operations, fairness across stakeholders, ease of measurement, and robustness against unintended consequences. The analysis showed a metric system consisting of a metric based on the inverse of the specific air range correlated with the maximum takeoff weight evaluated at 85% of maximum takeoff weight reasonably satisfied the key criteria.
