TU & Emissions Improvements

Please be aware of minor changes to TU & Emissions figures as we continually improve our methodology to bring you the industry’s most accurate data.

The data team at Cirium has updated the methodology which has a number of accuracy improvements resulting in changes to flight fuel and CO2 emissions figures.

Tracked Utilization also includes a number of data quality and coverage improvements resulting in more flights for more aircraft being tracked.
