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.

Water resource efficiency management system

ISO officially announced the ISO 46001 water resource performance management in 2019. To achieve systematic management, AUO introduced the system in 2020 on a trial basis. Based on the system‘s management requirements, we need to make an inventory of all the machines‘ water consumption status including production operation water supply model, monitoring and submitting the readings from the water meter, and system circulating water.

UL 3600 Circularity Certification

UL 3600 Circularity Certification assesses a company's circularity based on the recyclable content of a product and recyclability, as well as data such as factory waste disposal status. Since receiving the world's first UL 3600 Circularity Certification for the panel industry in 2020, AUO has been using UL's global safety science leader's circular certification standard UL 3600 to self-examine and improve circularity, and continues to promote circular product technology to various types of products.
