Greenhouse Gas Emissions

Greenhouse Gas Emissions

Confronted with the challenges of global climate changes, corporations must reduce GHG emissions. Suppose GHG emissions continue to increase, it will lead to risks such as increasing green costs (e.g., carbon taxes or fees), inability to meet customer demands, and failure to achieve carbon reduction targets. As a comprehensive technology service provider in the ICT industry, Wistron's initiatives in low-carbon manufacturing and green products and services will directly impact our competitiveness in the market. As such, we have set ambitious climate targets and established short-, medium-, and long-term decarbonization pathways. Beyond that, all locations are required to implement various energy conservation and decarbonization action plans each year to strive to reduce absolute GHG emissions.
