Green Cycle

Green Solutions for a Sustainable Production Environment

AUO is continuing to promote green production by improving our manufacturing efficiency and developing environmentally-friendly production methods. Our efforts include green factory, energy efficiency and carbon reduction, recycling, waste reduction and reduction of environmental burden. We are continuing to make progress in sustainable production and clean manufacturing.

Environmental management system

We have worked under the ISO 14001 environmental management system since 2002. This system also covers our domestic and overseas factories. A third party verifies whether or not those factories are compliant and the certificates are regularly renewed. Taking reference from its own thinking and the voice of the stakeholders, AUO uses the PDCA cycle for continuous improvement. The company uses policies, management task forces, and culture-based management. We systematically manage the environment, not only to ensure that the environmental management system is effective and legally compliant, but also to prevent environmental damage or pollution, and promote and achieve more environmental protection goals.

Energy management system

In 2011 we started implementing the ISO 50001 energy management system, and we had completed external certification work for the factories in Taiwan and Singapore,. and the Suzhou factory also obtained a similar certification in China. AUO’s internal auditing mechanism has embedded energy management deeply into its manufacturing.

Accomplishments in Green Production

Significant reductions in water and electricity consumption as well as carbon emissions have been achieved through green production.

Energy Use Intensity Reduction
40 %
Water Intensity Reduction
45 %
Process Water Recovery Rate
90 %
(G6 fab and above)
Carbon Emissions Reduction
62 %
Fabs with LEED Certification
4 Fabs
Environmental Goal 2020
Water 2020

Water resource has been identified by World Economic Forum (WEF) as the third most critical risk.

2020 Goals Current Situation In 2018
Water reduction - reduce water intensity by 17.5 / 30 % (58%)
Water neutrality - assist suppliers by saving 3,611 / 5,000 CMD (72%)

To support the government's reclaimed water policy, we assess to introduce 10,000 CMD of reclaimed water at production sites.

Carbon 2020

The carbon reduction target and path of Special Report on Global Warming of 1.5 °C (SR15)

  • Achieved net zero emissions in 2050
  • The total amount of carbon that should be reduced before the end of 2100 is 100 billion to 1 megaton
2020 Goals Current Situation In 2018
Reduce carbon by 79 / 1,000,000 tonnes (79%)
Environmental Burden
  • According to WHO's estimates, 7 million people die of air pollution each year
  • According to UN's estimates, electronic waste produced in world will amount to 200 Empire State Buildings in 2017
Current Situation In 2018 2020 Goals
Hydrofluoric (HF) acid waste is
1.81 kg/m2
Reduce in HF by 5% compared to 2014 (3.25 g/m2)
Sludge in total
23,064 tonnes
Reduce sludge by 16% compared to 2014 (31,778 tonnes)
Liquid copper waste is
0.03 kg/m2
Zero liquid copper waste
Volatile organic compounds (VOCs) is
1.20 g/m2
Reduce VOCs by 5% compared to 2014 (1.58 g/m2)
