## Overview

- **Description**: Data consolidation is made easy with access to Cirium’s unrivalled aviation data, using your Snowflake account. Cirium Sky Warehouse offers the 360-degree view of flight, providing access to a wealth of data across schedules, flights, passenger traffic, fleets and CO2 emissions.
Tell a story by fusing the flight, schedule, fleet and emissions with this sample data.
Cirium’s EmeraldSky CO2 Emissions data
fuses proprietary fleet, aircraft utilization and fuel burn models
which derive accurate historical and forecast flight emissions. It incorporates Cirium data covering
over 3 million flights per month across 900 airlines
(the active fleet globally). The methodology considers crucial factors which can impact the amount of emissions omitted such as
aircraft type and their attributes (winglets, engine type, age and more), flight duration (taxi and airtime), and passenger and cargo load
. Using the EmeraldSky methodology, Cirium has generated
over 150 fuel burn models to date.
This precise methodology allows businesses to make strategic decisions and reports based on superior emissions estimates for flights compared to other carbon calculation methods. Other methods rely on great circle distances between two points to derive generic estimates.
As part of a pre-market evaluation, we validated the CO2 emissions data with high-profile industry leaders such as
Virgin Atlantic and American Airlines
, who commended Cirium’s approach for estimating fuel burn and allocating emissions at a passenger level. Cirium’s CO2 emissions estimates have also been used by parent company
RELX in the company’s 2023 Annual Report.
