Commission the transportation company to handle the shuttle bus transportation business between the factory area of the Taiwan factory area, and began to disclose the emissions since 2014, using the mileage of transportation vehicles and the carbon footprint database built by the Environmental Protection Administration to estimate. The estimate emissions in 2019 were approximately 619 tonnes of CO2e, and the main fuel used was diesel.

Upstream transportation and distribution

Continue to promote local procurement,packaging material recycling, increasing loading rate and composite transportation since 2008 to reduce carbon emssions generated by distribution through green operations planning. Expand the scope of inventory since 2018 to conduct carbon reduction quantification calculated based on the parameters of weight and transportation mode and distance on the transportation activities of major materials. The estimated emissions in 2019 were 13,455 tonnes of CO2e.

Waste generated in operations

Since 2011, we established the carbon emission information of waste removal, transportation and treatment manufacturers from our vendors. The inventory category includes major wastes such as sludge, waste solvents, glass, acid, dust collection dust, empty barrels, and hardware. 2019 Carbon emissions from waste treatment are estimated at 7,574 metric tons of CO2e, covering more than 89% of the total weight of Taiwan.

Downstream transportation and distribution

In 2018, the carbon emission list for downstream product transportation and distribution was increased. The calculation method is the same as the upstream terms, which is calculated according to the parameters of the one-way weight of the product, including the transportation method and distance. The calculation scope includes the road transport carbon emissions from the factory area to the port and airport, and the total transport carbon emissions from sea, land and air transportation to the port and port. It was estimated to be 55,595 tonnes of CO2e in 2019.
