In order to fully implement the company’s sustainable development and carbon reduction goals, NAFCO has passed the ISO 14064-1:2018 greenhouse gas inventory verification of AFOR ASIA on October 24, 2023, and obtained the ISO 14064-1:2018 inspection certificate, with a 100% achievement rate.

In order to reduce the impact of greenhouse gas emissions on global warming, NAFCO has been committed to greenhouse gas inventory and carbon reduction related operations since 2022, and inventoried the direct and indirect greenhouse gas emission sources within the scope of its operation, so as to meet the needs of customers and other stakeholders for carbon emission information.


The company has completed the inventory of the total greenhouse gas emissions in the past two years, and has been verified by the third-party, AFOR ASIA: In 2021, Scope 1 GHG emissions were 140.49 t/CO2e, Scope 2 greenhouse gas emissions were 7510.58 t/CO2e, accounting for 20% of the total emissions, and Scope 3 (Scope 1 to 6) greenhouse gas emissions were 30,401.59 t/CO2e, accounting for 80% of the emissions.


In 2022, Scope 1 GHG emissions were 396.69 t/CO2e, Scope 2 greenhouse gas emissions were 8,722.23 t/CO2e, accounting for 76% of emissions, and Scope 3 (Scope 1 to 6) greenhouse gas emissions were 2,793.58 t/CO2e, accounting for 24% of emissions, for a total of 11,912.51 t/CO2e.


The Scope 1&2 GHG emission intensity in 2022 was reduced 4.63 t/CO2e per million, equivalent to 5.89 t/CO2e in 2021, a decrease of 21.3%. In 2023, a smart meter monitoring platform was established to effectively control the use of electricity and energy, and the greenhouse gas emission intensity of Scope 1 and Scope 2 in 2023 is expected to be continuously reduced by another 10%.


In response to the net zero emission in 2050, NAFCO will accelerate the promotion of various sustainability affairs, continue to optimize energy intensity, regularly disclose the results of greenhouse gas inventory, and review the effectiveness of energy conservation and carbon reduction year by year, initiate upstream and downstream carbon footprint management of products, and actively reduce the impact of product life cycle on the environment, so as to enhance the company’s sustainable operation strength and truly ESG transformation.

  •  Identify environmental considerations to prevent environmental pollution
  • To implement environmental management by identifying the impact that the company’s existing and future activities, products and services may have on the environment through environmental considerations.
  • Practice energy conservation and carbon reduction to protect the planet.
Nafco is mainly engaged in the design, assembly and maintenance of mechanical metalworking products, compared with other production, greenhouse gas emissions are smaller. However, in order to fulfill the responsibility of protecting the earth and respond to global climate change, we have set greenhouse gas inventory plans and reduction targets.
The energy resources we use include electricity and gas. Electricity is used to provide air conditioning, lighting and mechanical operation, etc., and is the main energy use of the company. Therefore, Nafco is committed to the implementation of energy conservation projects, for the management and technical aspects of the implementation, in order to reduce the consumption of energy resources to achieve the mission of environmental protection. Since its inception, it has promoted energy conservation and carbon reduction related matters, including greenhouse gas inventory and verification, the establishment of carbon reduction targets and the implementation of various energy conservation programs. Promote the power monitoring program to identify improvement opportunities through electricity consumption data collection and analysis, so as to improve the efficiency of electricity use.
  • Reduce the amount at source and properly recycle and reuse

The sources of the company’s business waste are mainly R&D materials, waste products, packaging materials and employee household waste. We reduce the impact on the environment through strict sorting and management mechanisms, and entrust legal and responsible recyclers to dispose of hazardous industrial waste. The principle of waste disposal is mainly recycling, and the parts that cannot be recycled and reused will be destroyed by crushing and other methods, and recycled and reused. Basically, it will not be disposed of in landfills, and some waste will be disposed of by incineration, and in the future, the goal will be to reduce the proportion of incineration and reduce pollution year by year.


Waste statistics: In 2021, the weight of hazardous waste was 134.86 tons (35% of the total) and the weight of non-hazardous waste was 252.43 metric tons (65% of the total), with a total weight of 387.29 tons.


In 2022, the weight of hazardous waste was 127.32 tons (31%), and the weight of non-hazardous waste was 284.71 tons (69%), with a total weight of 412.03 tons.

In 2023, the weight of hazardous waste was 241.91 tons (45% of the total) and the weight of non-hazardous waste was 293.63 tons (55% of the total), for a total weight of 535.54 tons.


The waste output intensity in 2022 was reduced to 0.209 tons per million, equivalent to 0.298 tons in 2021, a decrease of 29.8%. The waste output intensity in 2023 was reduced to 0.196 tons per million, equivalent to 0.209 tons in 2022, and then continued to decline by 6.2%.

  • Implement water conservation and proper treatment
The company does not use a large amount of water in the process, mainly for the domestic water of employees, so in addition to strengthening the promotion of water conservation for employees, it also introduces water-saving designs. In terms of sewage discharge, each plant has set up an independent sewage treatment plant, and all treatment processes comply with the requirements of environmental protection laws, so there is no impact on the surrounding surface water. In the installation, maintenance and maintenance of the sewage treatment plant, there are special personnel responsible for ensuring that the equipment and processes are kept in the best working condition. Besides, regularly entrust external environmental protection agencies to carry out inspection operations for the quality of the released water. The Government will also conduct irregular sampling and sampling audits in accordance with the laws and regulations.
The company’s production operations are mainly assembled, and the volatilization of smoke, vapors and organic solvents generated in the process is the focus of prevention and control. Formulate air control management measures to ensure that the exhaust gas generated by the activity is discharged after being treated by equipment or collected directly by windmills, and although the emission is extremely small, the concentration of harmful substances in the air is still regularly detected, and the test results are in line with the emission standards of local national laws and regulations. In addition, green processes are being further promoted, such as the replacement of original flammable organic solvents with low-pollution, environmentally friendly fluxes or water-based fluxes.

Upholding the belief that there is only one Earth, we actively improve our performance in climate change response, pollution prevention and control, energy and resource conservation, waste reduction, OHS management, and fire prevention to lower the overall environmental and OHS risk. We have also passed the certification for the ISO 14001:2015 Environmental Management System (EMS) to enforce environmental policy featuring respect and protection for Earth through the standardized routine management so as to fulfill our corporate social responsibility (CSR).


We began to actively engage in environmental protection and energy conservation, environmental education promotion, environmental protection and energy conservation culture building, and the implementation of measures related to environmental protection and energy conservation in 2019. Through continual process improvement and establishment and implementation of energy conservation policies, we aim to lower pollution, reduce energy consumption, and achieve eco-friendliness.

  • Carbon Emission Reduction

To enhance the efficiency of resources, we invest in energy conservation activities such as using the photovoltaic system, LED energy-saving bulbs, green power and energy, and inverter devices; replace the IE3 motors; and implement aircon automatic control. We have also many renewable energy certificates (RECs) to maximize the efficiency of energy and resources to effectively reduce carbon emissions. In 2023, Nafco recycled 221,094 kWh of solar energy, and obtained 63 renewable energy certificates from the Ministry of Economic Affairs. The real-time power monitor and management platform had been built in 2023 for the purpose of effectively improving the use of electric energy.



To cherish Earth’s resources and reduce environmental impacts, apart from implementing paperless operations (operations are done electronically), we also encourage employees to make photocopies on both sides of the paper and use recycled bin liners.

  • Water Conservation

To enforce environmental protection and value Earth’s resources, we have promoted the water conservation policy and taken related measures and invested in the wastewater treatment system and rainwater harvesting system to ensure water reclamation and reuse to practice CSR and protect Earth.
