Cirium’s Emerald Sky set to transform aircraft emissions and fuel burn data accuracy

Cirium, the leader in aviation analytics, has introduced the industry’s most precise independent standard for measuring aircraft emissions and fuel burn. 

This groundbreaking and revolutionary methodology analyses each flight’s specific aircraft type and design specifications, combined with real-time operational data and flight conditions, ensuring unparalleled accuracy and reliability in emission tracking.
Cirium’s Emerald Sky seamlessly integrates Cirium’s comprehensive data, advanced analytics, and innovative techniques to achieve unmatched precision in measuring both current and forecasted CO2 flight emissions.

Unlike traditional carbon calculators that depend on broad estimates and loose assumptions – such as using pre-planned routes instead of actual flown paths, and ignoring variables like wind speed and direction – Emerald Sky provides emissions results based on the seat in a specific class of service and sets a new standard in aircraft emissions measurement.   

Jeremy Bowen, CEO of Cirium, said: “Cirium’s mission is to establish the industry standard for accurate fuel burn and carbon emissions data to empower the aviation sector to deliver on its sustainability targets.

“Cirium’s world-beating methodology even considers each aircraft’s typical operating weight, passengers and baggage, cargo payload, and degradation in engine efficiency over time to provide the most accurate data available to help achieve aviation’s ambitious sustainability goals.”


Endorsed by airlines and industry stakeholders, Emerald Sky offers users access to both historical     data for up to five years and predictive carbon footprint for the upcoming 12 months.   

This robust data enables precise, independent assessment of each aircraft’s emissions, supporting more informed decision-making across the aviation sector. This ensures more precise flight emission reporting, which is critically important in meeting current and future climate regulations.

With superior data, Emerald Sky enables users to:

Undertake a thorough assessment of sustainable aircraft and fleet options
Identify opportunities for aircraft upgrades
Promote eco-friendly travel by providing sustainable flight options
Comply with emissions regulations and ESG reporting requirements
Evaluate investments in aviation carbon offset and elimination programs
Forecast the demand for sustainable aviation fuels (SAF)
Identify opportunities for aircraft upgrades.
In a world with an immense focus on the environmental impact of aviation, Emerald Sky’s rigorous approach is essential for accurate reporting and responsible aviation practices.

Emerald Sky supports Cirium’s ongoing mission to make a meaningful positive impact on the future of aviation and the environment, alongside the industry’s Net Zero targets
