Energy Management

Energy and electricity saving start from the purchase of green energy and electricity.

WT’s total energy consumption was 16,271‭ ‬GJ in 2022‭, ‬with an increase due to the inclusion of operating bases in China and South‭ ‬Korea in the scope‭. ‬The biggest source of energy was non-renewable electricity purchased from power companies‭, ‬accounting for 95.27%‭ ‬of the total consumption‭, ‬and the others were gasoline and diesel used by company fleet‭. ‬As of the end of 2022‭, ‬the non-renewable energy utilization rate was 100%‭, ‬and no renewable energy has been used‭. ‬The Shanghai Office is planned to be equipped with solar power generation systems in 2023‭ ‬to increase the utilization rate of renewables‭.‬

The total electricity consumption was 4.3061‭ ‬MWh in 2022‭, ‬of which the total electricity consumption in the areas where the GHG‭ ‬emissions inventory was verified‭ (‬logistics centers in Taiwan‭, ‬Hong Kong and Singapore‭) ‬was 3.0889‭ ‬MWh‭. ‬The electricity consumption intensity was 76.88‭ ‬kWh/m²‭, ‬down 0.63%‭ ‬compared to 2021‭.‬

As fuel consumption is closely related to the operating activities‭, ‬the combined energy intensity of gasoline and diesel was therefore measured by revenue‭. ‬In 2022‭, ‬the energy intensity of gasoline and diesel was 0.0013‭ ‬GJ/million NTD-revenue‭, ‬significantly down 18.75%‭ ‬from 2021‭.‬

Note 1‭:‬See 6-5‭ ‬GHG Inventory and Verification Situations for organizational boundaries‭.‬

Note 2‭:‬In 2022‭, ‬the operating bases in China‭, ‬Hong Kong‭, ‬South Korea‭, ‬and Singapore were newly-included in the voluntary inventory scope‭. ‬Due to the nature of electricity consumption in which form the majority of the energy was consumed by WT‭, ‬the energy consumption intensity was measured by floor area‭, ‬and the coverage rate of the energy disclose scope was 99.06%‭ ‬in 2022‭.‬

Note 3‭:‬The electricity data were taken from the electricity bills of each bases‭, ‬and the gasoline and diesel data were taken from the record on the CPC Electronic Billing and Collection System‭ (‬EBCS‭) ‬and the fuel invoices‭.‬

Note 4‭:Thermal conversion factor for electricity‭: ‬1‭ ‬kWh purchased electricity‭ = ‬0.0036‭ ‬GJ‭;‬

Note 5‭:‬Thermal conversion factors for fuels were taken from the Annual Energy Report of the Bureau of Energy‭, ‬Ministry of Economic Affairs‭, ‬which were 1‭ ‬liter of motor gasoline‭ = ‬7,800‭ ‬kcal‭, ‬and 1‭ ‬liter of diesel oil‭ = ‬8,400‭ ‬kcal‭.‬

Note 6‭:‬1‭ ‬kcal‭ = ‬4,186‭ ‬joules

Note 7‭:‬The electricity intensity was measured by floor area‭, ‬see Note 7‭ ‬for GHG Emissions Intensity‭; ‬the gasoline and diesel combined intensity was measured by annual revenue‭, ‬see 2-2‭ ‬Stable Financial Performance for operating incomes of the years‭.‬
