Value Chain Emissions Management
Carbon Reduction Commitments and Policies
AUO began auditing the GHG emissions of our global manufacturing sites in 2003, and the ISO14064 standard was introduced to disclose emissions-related information through external verification. We developed a digital platform internally in 2010 to systematically manage the organization‘s GHG emissions as a means to managing long-term operational carbon reductions.

Achievement
Full implementation of F-GHG management (scope1)
Reduction of fluorine-based gas emissions(F-GHG), with high greenhouse gas emission potential in the process, reaching destruction removal efficiency over 98.88%
Signed a memorandum with the Environmental Protection Agency to reduce F-GHG emissions by installing destruction removal facility: Local Scrubber (L / S) for new fabs.
Voluntary commitment to install destruction removal facility: Local Scrubber (L / S) for all existing fabs.
- All factories have installed L / S
- The installation rate is 100%
- Improve the performance of L/S
- Assist customers to meet the highest standards of EPEAT
- Applying artificial intelligence (AI) to improve the usage of F-Gas
