Commercial airliners monitor CO2 emissions


For the first time, aircraft data collected by commercial airlines has the potential to contribute to the monitoring of greenhouse gas emissions – an important step in managing the mitigation of such emissions.

An international research team that included Universities Space Research Association’s (USRA) Tomohiro Oda examined carbon dioxide (CO2) data collected over 34 global cities by Japan’s commercial airliners.

The study published in Scientific Reports shows for the first time the connections between urban atmospheric CO2 variability and emissions from cities, suggesting that aircraft data collected by commercial airlines can contribute to global greenhouse gases emission monitoring and their management to minimise their impact on climate.

Using instruments on Japan Airlines (JAL) commercial airliners, the Comprehensive Observation Network for TRace gases by AIrLiners (CONTRAIL) team used these unique aircraft observations to obtain high-precision atmospheric CO2 measurements.
