Value Chain Emissions Management

Environmental Sustainability Act on Climate Change

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.
