Due to the limitations of the Air Pollution Control Act in authorizing the control and management of construction machine pollution emissions domestically, the project starting from December 7, 2020, is implemented in a supportive manner. It aims to promote the self-management mark of construction machines（施工機具自主管理標章）, encouraging industry operators to actively perform maintenance and improve pollution emissions from construction machines. Subsequently, on July 1, 2023, the "Standards for self-management mark of clean emissions from construction machines（施工機具清潔排放自主管理標章規範）" were amended, providing a graded validity period for the certification. The project has gradually gained support from both administrative authorities and the industry.
The implementation of the new certification system brings several advantages, including an annual increase in the number of certified machines, a higher proportion of machinery within 5 years of age, and a gradual reduction in pollution degradation for machinery that has been certified for two consecutive years.
Based on the results of testing over 5,000 construction machines in previous years, it has been observed that the emission of smoke from mobile cranes is particularly severe. When these cranes on the road, they can adversely affect health and air quality. In order to regulate pollution emissions from mobile cranes, the project has completed the formulation of emission standards for imported mobile cranes (draft). For new machinery, detection data provided by the exporting country can be acknowledged. When it comes to used machinery, the planning adheres to the current self-management certification measures, which involve conducting black smoke tests. Compliance within the range of 0.8m-1 considered to meet the emission standards. Machinery that does not meet the standards can reduce emissions of smoke through by adjusting or installing installation of air pollution control devices. After implementing these standards, it is estimated that approximately 69.2 tons of NOx and 4.1 tons of PM can be reduced each year. This represents a 45% and 76% reduction, respectively, compared to the period before the standards were implemented.
