Greenhouse Gas Emissions

In response to the requirements of the Science Based Targets (SBT), the evaluation plan for Scope 3 Greenhouse Gas Emissions was implemented in 2021. The aim was to include broader upstream and downstream indirect emissions into our own greenhouse gas reduction scope. We hope to utilize Wistron’s influence and work towards the target of 1.5℃ of the Paris Agreement together with the world.

Greenhouse Gas Emissions Performance Indicators

Unit: ktCO2e CO2e/NT$ billion

Performance Indicators 2018 2019 2020 2021
Emissions per unit-revenue Local base 0.50 0.51 0.48 0.39
Market base 0.50 0.51 0.29 0.19
  • Note 1: Greenhouse gas emission intensity and target: Calculated based on the greenhouse gas emissions/plant revenue of Wistron's global manufacturing plants.
  • Note 2: Only Category 1 and Category 2 greenhouse gas emissions were calculated.
  • Note 3: Wistron is not responsible for the management of the Chongqing Plant dormitories.
