oneworld becomes first Airline Alliance to join IATA CO2 Connect
In a recent opinion poll, 90 per cent of travellers stated that they have a responsibility to
about the carbon emissions of their flight, but only two in five actually do so. While 84 per
cent of those surveyed acknowledged that it is easy to find tools to accurately estimate the
carbon emissions, about 90 per cent expect airlines or travel agents to provide them with
information.
The International Air Transport Association (IATA) and the oneworld
Alliance will now work together in the field of CO2 emission calculations
with all 13 oneworld member airlines committing to contributing
operational data to IATA’s CO2 Connect emissions calculator.
According to the associations, this will further improve the quality and
accuracy of the tool, as the percentage of airline-specific fuel burn data
used by the calculator will substantially increase, with the data provided
by the following oneworld member airlines: Alaska Airlines, American
Airlines, British Airways, Cathay Pacific, Finnair, Iberia, Japan Airlines,
Malaysia Airlines, Qatar Airways, Qantas, Royal Air Maroc, Royal
Jordanian, and SriLankan Airlines.
“Travellers want to make informed choices regarding their CO2
footprint and IATA CO2 Connect set out to provide CO2 emission
calculations based on operational data. We are delighted that oneworld
will become the first airline alliance to join this initiative, bringing in its
13 member airlines as data contributors. Their decision underscores the
importance of the industry’s objective of providing consistency and
alignment in this field,” said IATA Senior Vice President, Sustainability
and Chief Economist, Marie Owens Thomsen.
“oneworld is proud to be the first global airline alliance to support IATA’s
work to provide customers with high-quality estimates of the CO2
emissions of their flights. Our collaboration with IATA on CO2 Connect
will in turn help key players across the aviation sector, including airlines,
aircraft manufacturers and travel management companies among others,
to make better and more informed choices for travelers and enhanced
ESG reporting,” added oneworld Environmental and Sustainability
Board Chair and General Manager Sustainability, Cathay Pacific, Grace
Cheung.
In a recent opinion poll, 90 per cent of travellers stated that they have a
responsibility to know about the carbon emissions of their flight, but only
two in five actually do so. And while 84 per cent of those surveyed
acknowledged that it is easy to find tools to accurately estimate their
carbon emissions, the vast majority (90 per cent) expect airlines or travel
agents to provide them with this information, indicating a reliance on
the industry to proactively inform passengers about the carbon impact of
their flights.
IATA launched CO2 Connect in June 2022, with the objective of using
member airline data, such as fuel burn, belly cargo and load factors, to
provide high-quality per flight passenger CO2 emission calculations.
Paired with other IATA and open market data sources, IATA CO2
Connect calculates CO2 emissions for 74 aircraft types, representing 98
per cent of the active global passenger fleet, and considers traffic data
from 881 aircraft operators representing 93 per cent of global air travel.
Additionally, the IATA CO2 Connect data calculations are available to
industry partners through an API or flat file, as well as via airline sales
channels and travel management companies.
A Cargo calculator is also in development to launch in 2024, supporting
demands from shippers and freight forwarders to access accurate CO2
emissions derived from actual airline data.
Further, IATA CO2 Connect will continue to evolve and include new
features, having just launched a corporate reporting solution to support
the demand to accurately report CO2 emissions from business travel,
and next year will be introducing CO2 compensation solutions to
support airlines and other industry partners.
