Reusing packaging materials and recycling actively is the practice of circular economy

Since 2015, it has gradually reduced 3,153 thousand sheets of paper to reduce consumption.

WT introduced the advanced "Extended Warehouse Management" (EWM) in 2014. When designing the system architecture, it has incorporated the concept of green environmental protection into the operation process and operating system design.


Since 2015, the cumulative use of environmentally friendly cartons has reached 1,203 thousand items. Our customers want right-sized, recyclable packaging that minimizes waste and ensures damage-free delivery. We work to reinvent and simplify our sustainable packaging options using a science-based approach that combines lab testing, machine learning, materials science, and manufacturing partnerships to scale sustainable change across the packaging supply chain.

sustainable packaging

The reclaimed packaging materials maximum was 11% which contained the warehouse of Taiwan, Hong Kong, and China in 2020. WT are the circular economy pioneers, progressively implement source reduction, and recycle and reuse the empty cartons after purchase for shipping packaging. The packaging materials needed for our logistics operations, such as outer boxes, cartons, cardboard, etc., are all made of renewable materials, which can be recycled or composted and regenerated by nature.

Greenhouse Gas Emissions data, ISO 14064-1 certificated for 3 consecutive years

WT compliance with ISO 14064-1 to collect data of Greenhouse Gas Emissions1 since 2018 and the data quality was verificated by thirty independent parties the British Standards Institution (BSI). BSI holds the verification opinion statement with reasonable assurance about the data quality for the period from 2018 to 2020. WT reduces Greenhouse Gas Emissions. The Taiwan Zhonghe offices total GHG emissions in 2020 have been reduced which has aligned reduction targets baseline year in 2018 with a 1% goal.

The Greenhouse Gas Emissions for the period from 2020-01-01 to 2020-12-31 is 1,215.4193 tonnes of CO2 equivalent. Scope 1 emissions 200.4029 tonnes of CO2 equivalent and Scope 2 emissions 1,015.0164 tonnes of CO2 equivalent. The data has been certified by thirty independent parties.

The Greenhouse Gas Emissions for the period from 2019-01-01 to 2019-12-31 is 1,188.908 tonnes of CO2 equivalent. 2019 Scope 1 emissions 219.6633 of CO2 equivalent and Scope 2 emissions 969.2447 of CO2 equivalent. The data has been certified by thirty independent parties.

The Greenhouse Gas Emissions for the period from 2018-01-01 to 2018-12-31 is 1,245.533 tonnes of CO2 equivalent. 2018 Scope 1 emissions 204.4237 tonnes of CO2 equivalent and Scope 2 emissions 1,041.1094 tonnes of CO2 equivalent. The data has been certified by thirty independent parties.

The Greenhouse Gas Emissions in 2020 compares with an increase of 26.5113 tons of CO2 equivalent in 2019. This result is due to the fact that some offices have been leased since August 2019, so the data in 2019 statistics time is only 5 months, and the difference is between the complete annual data in 2020.
