WNC pays close attention to global environmental protection issues. Apart from observing local acts and regulations at each operations site and establishing environmental and green-product management systems with suppliers based on customer requirements, we have also realized energy conservation and carbon reduction in the work environments to ensure the effective use and management of limited resources. In addition, we have also formulated the EHS management policies listed below to implement measures and carry out internal and third-party audits at fixed, annual intervals to ensure they meet ISO 14001 and IECO QC 080000 related regulations.


WNC ESH Management Policies

  • In compliance with government policy and in coordination with ESH management system directives, promote environmental protection and the prevention of occupational diseases to provide employees with a safe and healthy work environment.
  • All employees must work in a concerted effort to design and manufacture green products with superior quality and minimize the impact and damage these products cause to the environment as much as possible to fulfill stakeholder demands and help protect the environment.
  • Continue to strengthen mechanisms for the prevention of environmental pollution, increase energy efficiency, and implement appropriate control and reduction measures to lessen the impact on the environment.
  • Continue to implement the workplace health management system and maintain good practices in the prevention of contamination and occupation-related illness. Adopt a “zero tolerance” principle toward unlawful conduct in the workplace to maintain the physical and mental health of employees.
  • Reinforce all employees’ ESH awareness and accountability, and provide appropriate communication and consultation channels and participation mechanisms to ensure the effective operation of the ESH Management System.


Green Products

In August 2011, WNC established a green-product section tasked with coordinating all internal and external matters relating to green products and to effectively monitor the environmental-product-development management process (such as assisting each unit on product design, manufacturing, and shipping).

WNC (Taiwan) Environmental-Management Targets and Effects


Energy Use Intensity

In 2016, because S1 operations commenced and WNC expanded its production capacity, the energy-use intensity of WNC (Taiwan) increased compared to the previous two years.

  • Average Water Consumption Per Person = Total Water Consumption(m³)/Total Employees
  • Average Wastewater Per Person = Total Wastewater(m³)/Total Employees
  • Electricity-use Intensity = Total Electricity Consumption (GJ)/ Individual Operating Revenues (NT$ million)
  • GHG Emission Intensity = GHG emissions (CO2e)/ Individual Operating Revenues (NT$ million)

*Note: The total employees include dispatch employees and contract employees.

Carbon Emissions Management

Since 2012, WNC (Taiwan) has defined our organizational boundaries in accordance with the guidance of the ISO 14064-1 standard and the GHG Protocol, with calculations of GHG emissions based on Scope 1 and Scope 2. The 2016 GHG inventory was completed in the first quarter of 2017, and the major greenhouse gases emitted include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons (HFCs). Due to the fact that S1, which commenced operations in the second quarter of 2016, was included in the inventory boundary as well as production-line relocation and capacity expansion, there was a significant increase in the total electricity consumption and GHG emissions. The GHG emission types and results of the GHG inventory in 2016 are presented in the table below.
