Trans-Pacific Climate Observing System

Since 2007, CAL has participated in the "Pacific Greenhouse Gas Measurement (PGGM)" program, which is supported by the Taiwan and EU governments and implemented by the National Central University . The In-service Aircraft for a Global Observing System (IAGOS) Instrument is installed on the No. B-18806 A340-300 passenger aircraft, which was officially launched on June 26, 2012, making China Airlines the only airlines in Taiwan, the first airline in the Asia-Pacific area ,the second airlines in the world to implement the EU IAGOS project. The upper-air observation data from the aircraft has contributed to the research of the institutes from Taiwan, EU and even the World Meteorological Organization (IAGOS) on the B-18806 A340-300 passenger aircraft. The device officially operated on Jun 26, 2012, making CAL the world's second, after Lufthansa, and Asia's first airline company to execute the IAGOS project. The aircraft was also the world's first civil aircraft equipped with IAGOS to collect high altitude gas data above the Pacific Ocean. The collected results have also been contributed to World Meteorological Organization's (WMO) and make which as an imoportant reference for the United Nations Framework Convention on Climate Change (UNFCCC). The outstanding achievements have been unanimously affirmed by the governments of Republic of China (Taiwan) and the EU, and have been selected for inclusion in the important deeds of the ROC (Taiwan) National Yearbook.

IAGOS Collect Atmospheric Data

The IAGOS carrier is installed below the cockpit. The detection instrument extends from the fuselage to collect atmospheric data (water vapor, ozone, carbon monoxide, NOx, carbon dioxide) during each aircraft range, and automatically connects to Taiwan's, Japan's, and European and American satellite systems after landing to transmit data to European research organizations and provide live observational air pollution and climate change data, thereby enhancing the construction of the global climate model.

Add Two Additional A330-300 Observation Aircrafts

The project achieved excellent results and was expanded since July 2016, adding two additional A330-300 observation aircrafts. CAL became Asia's first airlines company to observe pacific climates using dual type aircrafts. The project expanded to Oceania and assisted academic units in annual cost savings of approximately NT$1.4 billion in aircraft dispatch. The efforts demonstrated corporate social responsibility through the active contribution to global environmental protection.

Ecological Conservation

To support the Biodiversity Convention, CAL has implemented transport policies including the prohibition of transporting shark fin and experimental primates, vowing to stay clear of food ingredients of conservation species and participating in IATA related conservation transport operations discussions through the IATA EnCOM platform. CAL is planning on signing in 2017, together with other benchmark airline companies, the Declaration of the United for Wildlife International Taskforce on the Transportation of Illegal Wildlife Products, or the Buckingham Palace Declaration (More information), and to adhere to IATA's Guidance on Prohibited Carriage of Wildlife and Related Products by Passengers and commit to implementing subsequent IATA work plans, including: condemning illegal trades of endangered animals and animal products; increasing passenger, supplier,and staff awareness on the adverse consequences of conducting illegal trades of endangered animals.


Because of global warming and drastic climate change, relevant risks and carbon reduction are becoming a crucial sector in corporate management. Increasing number of investment institutes and corporate clients are requesting relevant data from corporations or their suppliers as a reference for investment or cooperation. Invited by the independent international nonprofit institute, CDP, CAL participates in carbon disclosure operations every year since 2012 to report environment management schemes, climate change risk management, and GHG verification data; and is the first transportation service corporation in Taiwan to participate in CDP operations.

Through long-term observation of climate change and carbon reduction topics, and active promotion of carbon management operations, CAL received CDP's rating as a Leadership A- in 2016 and 2018 and the best in the global aviation industry in 2018.

Also, in response to the Paris Agreement proposed during UNFCCC's COP21, CAL inspected the carbon reduction targets in 2016 to confirm the Company's compliance with the global carbon reduction targets, and had participated in the 2017 Science-Based Targets (SBT) initiative.

Disclosure of Carbon Footprint

The carbon footprint is defined to assess the environmental impact of a product or service from GHG emissions from raw materials, production, transportation, and usage to disposal throughout the life cycle. In order to fulfill carbon management and carbon reduction responsibilities, China Airlines not only monitors its overall carbon emissions on an annual basis, actively promoting various energy-saving operations for key emission sources and responding to the coming Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), but also assumes the role of consumers to analyze and disclose their flight carbon emissions with actual data from fuel consumption and passenger/cargo loadings according to ICAO and IATA calculator methodology. China Airlines also launched the ECO TRAVEL offsetting program from 2018 to assist its customers in making their journey net emissions carbon neutral or zero carbon emissions. For the walfare and sustainable development of future generations, China Airlines sincerely invites everyone to join the carbon reduction process, starting with understanding the journey carbon footprint and joining the ECO TRAVEL offsetting program.
