AUO EcoDuo PM220P00 multi-crystalline PV module obtains world’s first carbon footprint verification


AU Optronics has completed the carbon footprint verification on EcoDuo PM220P00, a multi-crystalline PV module, according to the international carbon footprint standard PAS2050. EcoDuo PM220P00 is the world’s first PV module to have obtained carbon footprint verification, reaching a critical milestone on carbon footprint management of PV key components. The product carbon footprint of EcoDuo PM220P00 refers to the total amount of carbon dioxide emissions, including the raw materials, manufacturing and distribution stages. By tracing the carbon footprint, AUO verified that raw materials took up around 82% of total carbon emission, manufacturing about 17% and distribution approximately 1%, among which raw materials led to the most emissions.


The findings inspired the adoption of innovative energy and materials-saving and replacement concepts in the early stage of R&D for solar cells, so that the overall amount of carbon emissions as well as product carbon footprint could be reduced substantially. Through continuous supplier training sessions, AUO developed the carbon footprint management program with its own e-system to collect suppliers’ carbon footprint data. The initiative significantly increased efficiency in carbon footprint management.
