Starting January 2025, airlines operating in EU airspace face a fundamental shift in environmental reporting. The European Commission's updated Monitoring, Reporting, and Verification (MRV) regulation extends beyond traditional carbon dioxide tracking to encompass non-CO₂ emissions (particularly contrails and nitrogen oxides).
With studies indicating that non-CO₂ effects account for 50-75% of aviation's total climate impact, this regulation represents more than incremental compliance. It's the foundation for how aviation's environmental footprint will be measured, compared, and eventually priced in the years ahead.
To help airlines navigate this complex transition, Estuaire has created a comprehensive guide: "Navigating 2025 Non-CO₂ Aviation Regulation."
Drawing on our analysis of real flight operations and deep understanding of climate impact modeling, this resource translates regulatory requirements into actionable strategy. Whether you're building your monitoring plan from scratch or refining existing data collection processes, our guide provides the technical depth and practical clarity you need to prepare confidently.
Here's what you'll get:
- A practical breakdown of input parameters – Understanding which data points drive your reported climate impact, how default values penalize missing data, and where to prioritize your monitoring investments
- How NEATS works – A clear explanation of the Non-CO₂ Aviation Effects Analysis Tool, the European Commission's platform for calculating and comparing climate impacts across flights and operators
- The data airlines should start collecting – Specific guidance on flight trajectories, aircraft properties, engine specifications, fuel composition, and weather data—with insights into collection feasibility and climate sensitivity for each parameter
The guide also includes a real-world case study examining one aircraft over one month, analyzing all flight tracks to demonstrate how different data inputs affect reported emissions. You'll see exactly how aircraft mass assumptions, engine configurations, flight trajectory timing, and fuel composition variations translate into calculated climate impact differences.
