Environmental Concern
The Daikin Group focuses on reducing both fluorocarbon emissions generated during product manufacturing and electricity consumption during air conditioner usage. Whilst creating thoughtful products, our Group also concerns about global warming issues.
01
How does global warming occur?
The Earth maintains a balance of heat: during the daytime, the sun’s heat warms the planet, while at night, this heat is radiated back out of the Earth’s atmosphere, thus maintaining an atmospheric temperature ideal for life. However, the increase of greenhouse gases like CO2 (carbon dioxide) traps heat, resulting in a rise in the Earth’s surface temperature. This phenomenon is known as global warming.


02
How does ozone depletion occur?
The stratospheric ozone of the Earth’s atmosphere protects us by absorbing the sun’s harmful ultraviolet (UV) rays. However, since the late 1970s, it has been discovered that the ozone layer above the Antarctic region has been thinning. Scientists have identified that such depletion was primarily caused by manufactured chemicals, particularly CFCs (designated fluorocarbons), which were commonly used as refrigerants in air conditioners and refrigerators that time.
To prevent refrigerants from entering the atmosphere, Daikin has been endeavouring to ensure that air conditioners and refrigerators that have reached the end of their useful life are properly managed by retail outlets.
03
How would air conditioner impact the environment?
The lifecycle of an air conditioner includes manufacturing, usage, recovery and disposal at the end of its useful life. During this lifecycle, air conditioners could have environmental impacts in two major ways:
1. Air conditioners require electricity to operate, and power plants generate CO2 (carbon dioxide) during the process of electricity generation. This is one of the causes of global warming.
2. The refrigerants used in air conditioners, once released into the atmosphere, could contribute to varying degrees of greenhouse effects. Although current mainstream refrigerants such as R-410A and R-32 would not cause ozone depletion, they could still contribute to global warming (the global warming potential (GWP) of R-32 is only about one-third of that of R-410A). Therefore, to prevent refrigerant leaks contributing to global warming, it is necessary to employ professional technicians to properly install air conditioners and ensure the appropriate recovery and handling of refrigerants.

DHK is committed to
- Making every endeavour to reduce the environmental impacts arising from our operations;
- Striving relentlessly to ensure our products are energy-efficient and contribute to pollution reduction;
- Making every effort to minimise waste generation by enhancing resource utilisation and efficiency;
- Complying with all relevant environmental legislation and codes of practice in Hong Kong;
- Improving our performance in environmental protection by enhancing the awareness and capabilities of our employees and sub-contractors through training.
Waste Collection Information
To facilitate proper handling of waste generated from used air conditioners or related materials, the Environmental Protection Department of HKSAR offers a list of chemical waste collectors and recycling points for residential, industrial and commercial users. Users are encouraged to contact these parties directly if needed.
