The European Commission is launching a new IT tool called the Non-CO2 Aviation Effects Tracking System (NEATS) to automatise the monitoring and reporting process. This tool aims to simplify the process for aircraft operators, requiring them only to input basic aircraft properties (such as type, engine identifier, and mass) and fuel properties. In case where no data is provided, default values will be used, offering the possibility of a fully automatic monitoring, reporting and verification process. 

NEATS automatically gathers and integrates most other necessary data, including flight information, trajectory details, and weather conditions. The collected data is then utilized in an emission module to initially compute emissions per flight. Subsequently, using open-source models, NEATS calculates the CO2 equivalent of these emissions for multiple time horizons (20, 50, and 100 years) based on the Global Warming Potential (GWP) metric. At the end of the reporting year NEATS will generate a report, which needs to be verified and submitted to the competent authority. 

When NEATS is not yet available at the start of the monitoring period, aircraft operators should at minimum collect the flight information (flight number; day and time of the flight; arrival and departure airport) and aircraft properties (aircraft type; engine UID; aircraft mass) per flight.
