Environmental Protection

WNC pays close attention to global environmental protection issues and trends. Apart from observing local regulations at our operation sites and establishing environmental and green-product management systems with suppliers based on customer requirements, we have also implemented measures in our work environments to conserve energy and reduce the carbon footprint in order to ensure the effective use and management of limited resources.

WNC's Environmental Goals

Energy and Resources Mangement

Renewable Energy

A total of 1,860 MWh of electricity was generated from WNC’s solar power plants in 2019, and approximately 1,090 tonnes of CO2e was reduced. The annual power generation equates to a carbon absorption capacity of approximately 2.8 times that of Daan Forest Park.

Note 1: By referencing the average solar radiation data provided by the National Aeronautics and Space Administration Atmospheric Science Data Center (NASA ASDC) at the locations of the solar power generating units, the projected energy generation can be estimated after all energy losses are deducted.

Note 2: According to the information released by the Energy Bureau of the Ministry of Economic Affairs in 2019, the Grid Emission Factor in Taiwan is 0.533 t-CO2e/MWh; according to the 2018 Baseline Emission Factors for Regional Power Grids in China (published by the Department of Climate Change of the National Development and Reform Commission), the Grid Emission Factor in East China is 0.8046 t-CO2e/MWh.

Energy Conservation

In addition to enhancing the resource efficiency of our product design as well as R&D and production processes, we have also implemented energy conservation and carbon reduction measures at our sites. These measures include recording and analyzing daily energy consumption, improving electricity usage efficiency, improving piping and electricial wiring, improving and/or replacing old facility equipment, and implementing various energy conservation programs. WNC has implemented the ISO 50001 energy management system and formulated specific improvement plans for its illumination systems, exhaust systems, air-conditioning systems and air compression systems.

Water Conservation

WNC operates in an R&D- and technology-intensive industry, and only tap water is used in its operations. In 2019, saved and recycled water made up approximately 14.8% of the total water withdrawn by WNC, which saved about NT$ 5.18 million in water withdrawal costs.


Carbon Emissions Management

WNC has been gradually expanding its business development and production lines, and thus electricity consumption has gradually increased each year. The main source of greenhouse gas emissions is externally purchased electricity, and Scope 2 greenhouse gas emissions account for more than 90% of the total greenhouse gases. To truthfully reflect the impact of changing production capacity on GHG emissions and reduction targets, emission intensity will also be presented to illustrate the relationship between production capacity and emissions. Due to the implementation of various energy-saving programs, total Scope 2 GHG emission intensity for 2019 decreased by 14.3% compared to 2016, which is an achievement rate of 143%. Given the establishment of the S2 and V1 sites, 

WNC Scope 2 GHG Emissions Intensity

(Total emission unit: tonne CO2e;

Emission intensity unit: tonnes CO2e/million NT$)

the base year for the GHG emission reduction target has been adjusted. A new GHG emission target has been set: reducing the total Scope 2 greenhouse gas emission intensity (tonnes of CO2e/revenues in millions of NT$) by 5% in 2022 (using 2019 as the base year).

Waste Management

Waste from WNC mainly comes from production processes. In 2019, WNC started implementing factory waste sorting optimization projects, which led to an increase in the number of waste sorting categories as well as reference photos being placed beside waste sorting bins to improve the accuracy of waste sorting and in turn raise the recycling rate. In addition, WNC has requested suppliers to recycle and reuse packaging materials, including trays used in manufacturing processes and cardboard boxes, to reduce the amount of waste from single-use items.

Green Products

WNC's Green Product Section is 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). The section's responsibilities include the evaluation and execution of compliance with international laws, regulations, and customer environmental-protection directives, promotion of green-product continual improvement initiatives, control of hazardous substances, and auditing of green products, management of suppliers, and ensuring the effectiveness of WNC's green policies implementation.
