Aircraft Maintenance

In compliance with corporate environment management mechanisms of international standards ISO 14001 and ISO 50001, CAL is dedicated to the details of daily aircraft maintenance operations. Energy saving and environmental friendly applications can be spotted throughout our operation processes.

Through the implementation of energy management system, CAL oversees major energy aspects in the operating environment. In conjunction with the company's carbon reduction targets, annual performance targets were established and executed. Key highlight measures are as follows:


  • Refitted scrapped fuel vehicles into electric vehicles, saving machinery equipment and energy expenditure.
  • Improved working environment, such as using light grey epoxy to paint the hanger floor to enhance the lighting effect.
  • Continued to promote the replacement of energy-saving lighting equipment, install automatic lighting controls, and enhance the behavior management.

CAL actively optimize operating process, and check and grasp the opportunities of water saving. At the same time, environmental friendly and water-saving cleaning technology for aircraft was introduced to reduce the consumption of water resources and detergents, such as ECOSHINE from 2016 and Callington cleaning program from 2020. Furthermore, the Maintenance Park recycles qualified discharge water for car washing, landscape pool refilling, plant watering, and initial washing of A/C wheel hubs. Total of 2,324 tons of treated wastewater was reused in 2020.


Set up professional wastewater plants and dedicated organizations for handling waste electrolyte (containing heavy metals, such as chromium and cadmium) from electroplating processes during aircraft maintenance and cleaning processes, and domestic wastewater produced within the Maintenance Park area. So far, wastewater treatment in the Maintenance Park area has reached 100% treatment and recycling target.

  • Filtered waste gas emission meet emission standard

A goal of 100% recycling rate has been established with the annual KPIs covering waste aviation fuel, lubrication oil, waste wooden pallets, waste metal, waste solution, waste solvents, waste plastic, waste paper, waste electric wires and cables, waste light sources, and kitchen waste, etc. In order to reduce the environmental load of waste materials.


Environmentally Friendly Offices

CAL's carbon reduction concept is implemented across daily office operations. We start from the details, with calculated resource consumption, of materials such as water, electricity, and paper, and thoroughly carry out our measures through implementing target management and staff education, thereby generating substantial carbon reduction benefits. The key measures are as follows:

Electricity Saving Efforts

Introduced renewable energy facilities (e.g., solar photovoltaic system), adjusted lighting control zone, replaced energy saving lighting equipment, installed variable frequency drive (VFD) equipment, replaced energy-intensive equipment, optimized air conditioner settings, regularly examined electricity consumption, and promoted energy saving habits.

Fuel Saving Efforts

Gradually promoted the procurement of low-carbon / electric transportation equipment, prioritized the procurement of hybrid business vehicles, controlled the use of business vehicles, performed regular maintenance services for old vehicles, and promoted policies for low carbon drivers and combined crew vehicle schedules. Regularly review fuel consumption and promote fuel-saving/environmental driving concepts.

Water Conservation Efforts

Set up rain water recycling systems, increased waste water recycling rates, adopted products with Water Conservation Mark, regularly reviewed water resource consumption, and promoted concepts of water conservation.

Paper-Saving Efforts

Promoted paperless processes, adopted double-sided printing and rationing system.

Waste Reduction Efforts

Monitored and reviewed the overall waste output, performed waste management using five major principles: Refuse, Reduce, Reuse, Recycle and Repair, to increase rate of recycle and reduce use of waste products.

Green Buildings

China airlines has designed and developed its headquarters buildings based on the four major indicators of green area, base water conservation, daily energy saving and water resources. It has obtained the Green Building Candidate Certification before its operation in 2010. The management and hardware upgrade operations, we won Diamond-grade green building label at the Administration Center and Crew Center Building granted by the Ministry of the Interior in 2017 and 2018.


Energy-saving outer walls

Low-E (low radiant) glass and sun shading boards are used in exterior walls to reduce radiant heat. In cooler seasons, natural ventilation and roof heat insulation devices are used to reduce the use of air conditioning and thereby saves energy. Fine lighting can also reduce lighting loads.


Air conditioning

Use the systems of VFD Chiller which can automatically control the number of units according to the temperature and loads. The systems can save 20% electricity consumption than non-variable frequency systems. We also set up the office circulation fans to adjust indoor wind field and have better comfort environment for staff.


Energy-saving lighting

Open windows to let in the natural sunlight and use the high-efficiency lamps in office area, such as energy-saving label LED lamps with one-by-one configuration and hand loops.


Adjusting the amount of contracting electricity

Depending on the power consumption of CAL headquarter, the contractual capacity of the electricity gradually reduced from 6,000KW in 2010 to the current 2,700KW.


Special tiles capable of grass

A multi-layer planting method is adopted; Trees on the upper layer have a space of 5 to 6 meters in between, so that seedlings can have sufficient room to growth, whereas every 9 to 25 bushes on the lower layer occupy a space of one square meter. The grasslands are decorated with plants of various colors in different seasons.


Water retention and green planting

Water retention is part of the ecological water cycle. China Airlines expanded the green spaces and covered them with special titles capable of grass to boost the site's permeability and water retention.


Water saving devices

Use water-saving label products and devices, including water-saving faucets and toilets, automatic flushing sensor system and off-peak electricity timing irrigation system. All of these devices can save 15% to 20% of water use.


Water recycling system

Set up a rainwater recycling system and adjust the pipeline to recycle from the reclaimed water of central water dispenser and the crew training pool, and to use it as toilet water and watering garden plants. The recycling water system has a capacity of 1,300 tons.




Quality of drinking water

Adopted the central drinking water system, the drinking water end has both energy-saving and water-saving labels, and the water is regularly tested in accordance with drinking water quality standards.


Air Quality

Based on different spatial characteristics of the three buildings, central air-conditioning system and outside air ventilation system are installed to provide better air quality.


Use of green building materials

Offices, general training classrooms and conference rooms are built with green building materials, including water-based Eco paints and light-gage partition walls, etc. All these materials are of low fugitive emission, low pollution and low odor, that pose less harm on health.



Recyclable building materials

Major building materials, including structural steels, roofs, wall metal panels, glass curtains, natural stones etc., are all recyclable. Recycle and reuse waste resources at the construction sites. For example, concrete chunks are shattered and further used as the material for roadbeds in the CAL Park area.
