A metric proposed as part of the International Civil Aviation Organization’s plan to curb greenhouse gases in the airline industry will mask the actual emissions of aircraft, according to an aeronautical engineer.

The proposal uses a plane’s maximum take-off weight, a certification level known as MTOW, to help determine emissions and whether the aircraft is efficient enough to fly, said Dimitri Simos, founder of Lissys Ltd., an airline-engineering software company near Leicester, England, whose clients have included Boeing Co. and Airbus. Lissys’s Piano software has been approved under ICAO’s models for determining fuel burn.
