Purchased goods and services

Voluntary inventory management has been conducted since 2016. Key materials identified include glass substrate, liquid crystal, photoresist, developer, etchant, stripper and thinner. Green manufacturing is also used to reduce carbon emissions and environmental impact. Total emissions for 2018 were approximately 362,028 tonnes CO2e in total.

In 2008, AUO launched the green logistics plan to reduce carbon emissions from distribution activities through local purchasing, recycling of packaging materials, increasing load-factors and intermodal transport. Inventory scope was increased in 2018 to quantify carbon emissions from the transport of key materials. Total emissions were estimated to be 3,717 tonnes CO2e based on weight, mode of transport, distance and other parameters.

Waste generated in operations

The tracking of GHG emission intensity data for waste disposal and waste contractors commenced in 2011. Carbon emissions were calculated using the actual amount of waste removed and processed each year along with reasonable coefficients based on experience. The types of waste surveyed include sludge, organic solvents, waste glass, waste acid liquids, waste dust, empty barrels and scrap metals. Carbon emissions from waste disposal totaled approximately 12,042 tonnes CO2e in 2018 and accounted for more than 83% of all waste in Taiwan.

Employee commuting

The tracking of carbon emissions generated by employees at Taiwan sites when commuting to and from work started in 2014. Average employee commute distance and the carbon emissions they generated were calculated using the latest statistics issued by the MOTC. Carbon emissions totaled approximately 20,207 tonnes CO2e in 2018; this included cars and motorcycles.

Downstream transportation and distribution

Carbon inventory for downstream product transportation and distribution was included for the first time in 2018. Just like upstream transportation and distribution, calculations are based on product weight per trip, mode of transport, distance and other parameters. Scope of calculation includes product carbon emissions when transported by road from the factory to the port or airport as well as the carbon emissions for transport by sea or air to the destination port or airport. Total emissions were estimated to be 69,525 tonnes CO2e.
